Posted on by pengwei 139

Hi,

 

I have used an UploadFile control to upload a .txt file to my Power App. How can I convert the file content into plaintext to be shown in a label?

 

the file content is in this format

 

"data:text/plain;base64,UGVyc29uIEE6IEh.........................HMuDQoNCg=="

    Hi @pengwei ,

     

    We can pass it to flow and decode it.

    Hi @v-xiaochen-msft 

     

    This is also my current way of working. However, I want to remove the flow. Is there any Power Apps functions which can achieve that?

     

    Hi @FLMike 

     

    It's a text file with meeting minutes.

    Hi @pengwei ,

     

    Unfortunately, functions in canvas cannot decode base64 strings.

     

    Best Regards,

    Hi @v-xiaochen-msft 

     

    Since there is no functions available, I will keep using the flow as the workaround. Thank you and @FLMike
