What is the TOJSON Function?
The TOJSON function is a DAX function that converts a table of data into a JSON-formatted string. The function takes one argument, which is the table you want to convert. The resulting string can be used to export the data to a JSON file or used in other tools that accept JSON input.
How to Use the TOJSON Function
To use the TOJSON function, you first need to create a table of data in Power BI. Once you have your data, you can use the following formula to convert it to a JSON-formatted string:
In this example, "Table1" is the name of the table you want to convert. You can replace this with the name of your table.
You can then use this string to export the data to a JSON file. To do this, follow these steps:
1. Click on the "Export data" button in the Power BI ribbon.
2. Select "JSON" as the file format.
3. Choose a location to save the file.
4. Click "Export" to save the file.
And that's it! You now have a JSON file containing your data.
Why Use the TOJSON Function?
There are several reasons why you might want to use the TOJSON function in Power BI. Here are a few:
1. Exporting Data to Other Tools
Many tools and services accept JSON input, so being able to export your data to a JSON file can be useful. For example, if you're working with a web application that uses JSON data, you can use the TOJSON function to export your data and use it in your application.
2. Storing Data in a Database
JSON is a popular format for storing and exchanging data, so you might want to store your Power BI data in a JSON format in a database. The TOJSON function makes it easy to convert your data to a JSON format that can be stored in a database.
3. Sharing Data with Others
If you need to share your Power BI data with others, exporting it to a JSON file can be a convenient way to do so. The recipient can then use the file in other tools that accept JSON input.
The TOJSON function in Power BI is a useful tool for converting a table of data into a JSON-formatted string. This string can be used to export your data to a JSON file or used in other tools that accept JSON input. Whether you're exporting data to other tools, storing data in a database, or sharing data with others, the TOJSON function can help simplify the process.
