Описание

Мы собираемся импортировать таблицу с этой страницы. Когда мы пытаемся изменить тип данных для столбцов с датой, то возвращается столбец с ошибкой DateFormat.Error.

Решение

Если не получается преобразовать столбец с текстом в дату, то значит в строке присутствуют лишние символы.

С помощь функции Text.Length мы можем убедиться, что длина строки намного больше, чем ожидается. Мы видим 10 символов, но функция возвращает 15.

С помощью функции Text.Start извлечем 1 символ сначала строки. Потом получим код этого символа с помощью функции Character.ToNumber. Получаем 8206.

Далее воспользуемся функционалом замены подстроки и исправляем получившуюся формулу:

Table.ReplaceValue(
      get_table, 
      Character.FromNumber(8206), 
      "", 
      Replacer.ReplaceText, 
      {
         "Дата начала купонного периода", 
         "Дата выплаты купона", 
         "Дата фиксации списка держателей"
      }
   )

Примененные функции

Text.Start
Character.ToNumber

         "Дата выплаты купона",

September User Group Success Story: Reading Dynamics 365 & Power Platform User Group

The Reading Dynamics 365 and Power Platform User Group is a community-driven initiative that started in September 2022. It has quickly earned recognition for its enthusiastic leadership and resilience in the face of challenges. With a focus on promoting learning and networking among professionals in the Dynamics 365 and Power Platform ecosystem, the group has grown steadily and gained a reputation for its commitment to its members!

The group, which had its inaugural event in January 2023 at the Microsoft UK Headquarters in Reading, has since organized three successful gatherings, including a recent social lunch. They maintain a regular schedule of four events per year, each attended by an average of 20-25 enthusiastic participants who enjoy engaging talks and, of course, pizza.

The Reading User Group’s presence is primarily spread through LinkedIn and Meetup, with the support of the wider community. This thriving community is managed by a dedicated team consisting of Fraser Dear, Tim Leung, and Andrew Bibby, who serves as the main point of contact for the UK Dynamics 365 and Power Platform User Groups.

Andrew Bibby, an active figure in the Dynamics 365 and Power Platform community, nominated this group due to his admiration for the Reading UK User Group’s efforts. He emphasized their remarkable enthusiasm and success in running the group, noting that they navigated challenges such as finding venues with resilience and smiles on their faces. Despite being a relatively new group with 20-30 members, they have managed to achieve high attendance at their meetings.

The group’s journey began when Fraser Dear moved to the Reading area and realized the absence of a user group catering to professionals in the Dynamics 365 and Power Platform space. He reached out to Andrew, who provided valuable guidance and support, allowing the Reading User Group to officially join the UK Dynamics 365 and Power Platform User Groups community.

One of the group’s notable achievements was overcoming the challenge of finding a suitable venue. Initially, their «home» was the Microsoft UK HQ in Reading. However, due to office closures, they had to seek a new location with limited time. Fortunately, a connection with Stephanie Stacey from Microsoft led them to Reading College and its Institute of Technology. The college generously offered them event space and support, forging a mutually beneficial partnership where the group promotes the Institute and encourages its members to support the next generation of IT professionals.

With the dedication of its leadership team, the Reading Dynamics 365 and Power Platform User Group is poised to continue growing and thriving! Their story exemplifies the power of community-driven initiatives and the positive impact they can have on professional development and networking in the tech industry. As they move forward with their upcoming events and collaborations with Reading College, the group is likely to remain a valuable resource for professionals in the Reading area and beyond.

September Featured User Group Leader

Ayonija Shatakshi, a seasoned senior consultant at Improving, Ohio, is a passionate advocate for M365, SharePoint, Power Platform, and Azure, recognizing how they synergize to deliver top-notch solutions. Recently, we asked Ayonija to share her journey as a user group leader, shedding light on her motivations and the benefits she’s reaped from her community involvement.

Ayonija embarked on her role as a user group leader in December 2022, driven by a desire to explore how the community leveraged various Power Platform components. When she couldn’t find a suitable local group, she decided to create one herself!
Speaking about the impact of the community on her professional and personal growth, Ayonija says, «It’s fascinating to witness how everyone navigates the world of Power Platform, dealing with license constraints and keeping up with new features. There’s so much to learn from their experiences.

Her favorite aspect of being a user group leader is the opportunity to network and engage in face-to-face discussions with fellow enthusiasts, fostering deeper connections within the community. Offering advice to budding user group leaders, Ayonija emphasized the importance of communication and consistency, two pillars that sustain any successful community initiative.

When asked why she encourages others to become user group leaders, Ayonija said, «Being part of a user group is one of the best ways to connect with experienced professionals in the same field and glean knowledge from them. If there isn’t a local group, consider starting one; you’ll soon find like-minded individuals.»

Her highlight from the past year as a user group leader was witnessing consistent growth within the group, a testament to the thriving community she has nurtured. Advocating for user group participation, Ayonija stated, «It’s the fastest route to learning from the community, gaining insights, and staying updated on industry trends.»

Just like any other language, Power Query has its own different types of errors, one of them is DataFormat Error.

Dataformat errors in Power Query are mostly data type errors and do not prevent you from loading data to Power BI, instead the cells will be loaded as blank. The screenshot below shows 3 errors for 78 records when the data is loaded to Power BI.

To audit the error or get more details, do the following:

Click on View errors from above to go back to Power Query Editor
In Power Query Editor-> Select View tab -> Check Column Quality

For this example, UnitsInStock has 3% error for all rows in that column.

3. Click on Kept Errors under Applied Steps to see only rows with errors, the Kept Errors step is automatically added when you click on View errors from step 1.

Below screenshot show 100% error for the 3 rows.

4. To see details of the error, select the error as seeing below:

For this example, the error occurs because the column data type is Number, but 3 rows in the column has Text values, Power Query return error because it cannot convert the Text values to Numbers.

DataFormat.Error: We couldn’t convert to Number

5. To audit the error, create a custom column using the try expression, from Add column -> Custom Column -> type the expression below. A new Record column will be created.

6. Click on Expand -> Select Error

7. Click Expand again -> Click OK

You will see the Reason, Message and Detail of the error. You can load the error details to Power BI and create an Audit report if needed.

Also, you can use this report to make changes to the affected values at Data source level and reload to Power BI.

8. To replace the errors in Power Query from Advanced Editor, add a line of code to the MQuery with the value to replace with.

For this example, I am replacing all errors with 0. Optionally, you can replace the errors by right clicking the column, then select Replace Error.

Note: Those new values from Power Query will not be updated to your source data.

9. Click on Enable Load to load the data to Power BI if its not enabled by default, right click on the query from the left and select Enable load.

10. Click Close and Apply

The data will now load and apply all changes successfully without errors.

Happy Auditing! 🙂

Приветствую! Сделал слияние таблиц по одному столбцу, в Power Query. При подключении сводной таблицы к данному запросу выдает ошибку:

Цитата
DataFormat.Error: Не удалось преобразовать в число

Сохранил в запросе строки ошибок получил следующие:

Цитата
DataFormat.Error: Не удалось преобразовать в число. Сведения: (пусто)

Проверил исходники, на наличие символов, ничего не обнаружил. Сводная успешно подключается к запросом по отдельности, но при слиянии начинает выдавать ошибку. Пробовал заменить «пустоту» на «-«, результатов не дало, ошибка осталась прежней.
Принцип слияния:

Скрытый текст

Исходный файл, много весит, не могу загрузить( Пробовал хоть как то изобразить в файле примере, но ошибку не выдает.
Подскажите пожалуйста в чем может быть причина. Спасибо!

Dark1589 Пользователь Сообщений: 487 Регистрация: 22.11.2017	Xat, где-то текст попал в числовой столбец. Сам запрос получается выгрузить на лист?

Xat Пользователь Сообщений: 169 Регистрация: 16.01.2018	Dark1589, Нет, тоже ругается. При слиянии, я разворачиваю только два текстовых столбца.( без столбца артикул) По факту числовых столбцов не прибавляется Изменено: Xat — 15.10.2019 16:11:45

	Xat, запрос ругается на формат данных, говорит, не удалось преобразовать в число, почему бы не дать ему, что он хочет? Вы меняете пустоту на «-«, замените лучше на null или 0.

Dark1589 Пользователь Сообщений: 487 Регистрация: 22.11.2017	Xat, в запросе слияния попробуйте убрать шаг определения типа данных и покопайтесь в фильтре. Возможно косячное значение будет как раз внизу или вверху списка в одном из столбцов

Dark1589,Тип данных не меняет(шаг отсутствует). В фильтре , в самом низу , где обычно загрузить еще данные, светится эта же ошибка((
Я правильно понимаю, чтобы заменить пустоту, я в запросе выставляю только то, на что необходимо заменить,? или в PQ пустота как то называется ?

Xat написал: DataFormat.Error: Не удалось преобразовать в число.Сведения: (пусто)

Это значит у вас имеются столбцы с числами, и одновременно пустыми ячейками, но ячейки эти не совсем пустые, а в них имеется так называемый нулевой текст, в Экселе это выглядит как =»». Перед присвоением типов столбцам такие пустые значения нужно заменить на null кодом типа такого:

Код
let Source = Table.FromColumns( {{null, "", null, ""}} ), ReplacedValue = Table.ReplaceValue(Source,"",null,Replacer.ReplaceValue,Table.ColumnNames(Source)) in ReplacedValue

меняет во всех столбцах нулевой текст на null

Xat, не можете показать данные, покажите хотя бы коды всех запросов, которые используются в книге.
Еще попробуйте выгрузить каждый из запросов по отдельности в таблицу на лист, и посмотрите будет ли он при выгрузке показывать что в ней есть ошибки. Тогда тыкнете в это сообщение и вам сформируется запрос показывающий эти ошибки.

Вот горшок пустой, он предмет простой…

Нашел в чем была ошибка, действительно в столбце «арт» попал текст, но я пытался исправить это в последнем шаге » изменить тип» , а надо было в самом первом. Так как с самого начало там где был текст в столбце, тянулась «error», и соответственно ни как не исправлялась в нужный арт. Изменено: Xat — 17.10.2019 11:24:38

Have you ever been working with a new Power BI Dataset and received a DataFormat.Error notification while working with your data model? It can be very frustrating and confusing, but we will walk through a few ways you can address the Power BI error and avoid it in the future.

It’s worth noting that this error can show up in both the Microsoft Excel and Microsoft Power BI. Both pieces of software use Power Query to import and prepare data for further processing.

In this example, we will use Power BI, but the steps to correct will be similar in Excel.

What Causes a Power Query DataFomat Error?

DateFormat errors occur when a failure occurs when converting data types. Data types are important in Power Query because the software needs to know how to interact with software. For Example, Power Query will add two numbers and produce the sum but when asked to add two pieces of text it will concatenate them together into a longer string.

The computer would be unable to calculate the sum of the number 15 + the text “Apples” and causes an error message.

Step 1.) Right Click the Table Name and Edit Query

The first step is to launch the Power BI Query Editor. You can do this either from the Report View or Data View selected on the left side of the screen, and right click the table name you are importing and click on Edit Query.

Step 2.) Identify the Applied Step Causing Error

The Applied Steps panel on the right side of the screen will show each data transformation step that happens when the data is being loaded into Power BI. Most often this will be the Changed Type Step.

The current column data type is noted at the top of the column with a small icon of numbers, a calendar, letters etc. You can also right click on the column and go to Change Type, it will show you the selected data type for that column.

Note: Another option for quickly identifying the assigned data type, and the step that it’s occurring is by using the Advanced Editor, available under the View tab. It will show you the Power Query Formula Language, also called “M”.

Step 3.) Fix a DataFormat Error by Changing Data Type

To correct the error, you need to assign the correct data type to the column.

You can do this by right clicking on the column name, select Change Type and select the appropriate data type. In our Example, we will change the data type of the Sales Qty column to Whole Number.

Correcting DataFormat Error by using Replace Error

A second option is to Right Click on the Column Name, and click on Replace Error.

The screen will allow you to do a “Find and Replace All” for a specific value within the dataset. For this method to work, you would need all of the errors to be caused by a similar set of values.

If it is a handful of values, you can click on an individual error and view the value that is causing the error. The example below shows that the Sales Qty column has a numeric data type, but one cell has the word “Zero” in it causing the error. You could use Replace Error to change “Zero” to 0

Identify Errors Using Power BI Column Quality Preview

Microsoft Power BI has several capabilities to perform data analysis and to preview the data brought into your data model. You can turn on Column Quality under the View section of the Power BI Toolbar.

Column Quality will show you how many errors you have in each column. If you’re unable to change the data type in your column, you can right click on the Column Quality preview Remove or Replace errors from here.

You can click on Keep Errors to filter the view to a list of all errors within the column.

Using Chat GPT to Reconcile Errors and Write Formulas

Chat GPT is a Natural Language Processing chat bot developed by OpenAI. It’s been trained to understand and respond to requests in many different languages. It’s an incredibly valuable resource for asking questions about Power BI, whether you’re trying to better understand the meaning of an error or write a custom DAX Formula.
