Step 1. Add image, button and text controls
In the screen where the base64 format is required, add an image, button and text controls.
Step 2. Set up value for the Image control
Select the image and in the “image” property, add the following formula:
Last(Table_Attachments).File.Value
Last(Table_Attachments) can be replaced by ThisItem. If the image is in a gallery, or by a variable name that contains the file you want to convert.
Step 3. Set a variable with the base64 content
In the button, add the following code on the OnSelect property:
Set(
varFiletoBase64,
JSON(
Image1.Image,
JSONFormat.IncludeBinaryData
)
)
Step 4. Use the variable
Now the varFiletoBase64 variable contains the representation of the file in base64 format. You can use it in the application as required.
For this simple example we are just displaying it in the text control:
Power Apps allows converting Dataverse files into base64 format by using the JSON PowerFx function in combination with the image control and save this result into a variable that can be used across all the application.
