How to do base64 decoding as MP3

[Elsa]

Hi everyone,

I’ve just started using Make, and I’m trying to create a workflow that uploads a Google TTS-generated MP3 file to OneDrive.

The automation runs successfully and the MP3 file is uploaded to OneDrive, but the file seems to be damaged — it can’t be played after upload.

Could someone please help me troubleshoot or repair this issue? Any guidance or example workflow would be greatly appreciated.

Thank you so much for your help!

Hey Elsa,

you need to fix the formula in the second screenshot. At the moment you have free text and not the actual toBinary() function. Try selecting it from the menu instead.

Hi Stoyan,

Thanks for your help, but it still doesn’t work.

Originally, I thought the issue was caused by the audio file being too long,
so I tried reducing it to 20 seconds and used the Binary() function.

However, it still doesn’t work.
