Hello,

I'm struggling with the file content coding of pdf files.

I'm trying to convert the file content of a pdf to a string (so I can later modify it, but as a first step, I'm not changing it at all)

So I'm trying to convert the base64 file content to string (in the first compose action) and then put it back together as the proper file content json in the second compose action and then attach it to an email.

If I get the file content from OneDrive directly, the file that arrives looks like the coding on the left. If I do my two steps, I get the result on the right. How do I fix that?

Thank you!

Hi @schwibach ,

As far as I know, this method may not be able to extract text strings from PDFs.
I recommend you to use the Recognize text in an image or a PDF document action in AI builder.
Or there is a ready-made template in flow to help you extract strings from PDF:
Extract text from images or PDF documents using AI Builder Text Recognition | Microsoft Power Automate
I this this link will help you a lot :
Use the text recognition prebuilt model in Power Automate - AI Builder | Microsoft Docs

Best Regards,
Levi

Re: PDF file content coding problem

Thank you... Well, I already know what text to expect because it's a placeholder that I put there.

What I want to do is replace a specific string (that I know is inside the pdf) and replace it with another string.
