How to check if two PDF files are internally identical

I have a need to check two PDF files to know if they are internally identical, to confirm that a function has completed successfully.  Any way to do this?

 

Thanks.

Hi,

Never tried this before. Maybe you can get file content for both pdf in base64 and match its values using condition. 😁

Hi @martinav  I'm fairly certain you an do this with an AI Builder Form processor model. Take a look at the AI Builder component and in the AI Builder forum.

 

Cheers,

Aman

@Sumen ,

 

This is a good idea.  However, I was unsure how to set an equality for these very long strings of data.  I did try it using a Condition action, but I was uncertain it was truly comparing the two properly.  I believe I was getting both false positives and false negatives.  I bailed on it then.  This was a couple of years ago.

Hi @martinav ,

 

Yeah, the strings are terribly long. I dont know that, you have already done this or not. Just a suggestion, you can pass both of the file content into 2 separate string e.g passing file content to a string field like this - body('Get_file_content')?['body']?['$content'] and compare those 2 super long text in any online text compare tools (https://text-compare.com/). If the results is identical, maybe you can compare those string variables back inside a condition. Another thing,  you can also pass

decodeBase64(body('Get_file_content')?['body']?['$content']) to the string variable then match the whole content again with a condition. Hope to see how this turns out! 😁
