Number of pages in a PDF file

[nana001]

In a Flow I am building I would like to obtain the number of pages in a PDF document. Is there anyway?

Hi @nana001 

Unfortunately using Power Automate this won't be possible to do.

Thanks

Abm, thanks for your message. 

The only other potential solution that I could find is reading the PDF file in plain text as suggested here: Solved: Re: Extracting PDF meta data and document info - Power Platform Community (microsoft.com)

However, I cannot seem to decipher the "/Pages" metadata for a PDF file. I looked through the ISO reference. Any idea how to potentially read a PDF file in plain text to get the total number of pages in it?

Dear @abm @nana001 

         I found an imperfect solution for counting pdf pages in Power Automate: Here is the procedure for your reference:

1: extract your pdf file and set "the index numbers of the pages " to large quantity which is clearly pages out of bounds to make error-"Page out of bounds"  happen .  😀

2: Make sure continue flow run in Advanced: Page out of bounds and set " Go to next action" only.

3: Get the last error and capture the error message, then split text by "," and get the textlist[1],  Convert to number, then -2 and get the right page number now.😀

@nana001  You can do this in a cloud flow quite easily:

Simply get the file content of a PDF file. And then create a compose action with the following expression:

sub(length(split(replace(base64ToString(outputs('Get_file_content')?['body']['$content']), 'Type/Pages', ''), 'Type/Page')),1)

This will return you the count of pages within the PDF file.

It works. Thank you.

@seewo Couldn't get the proposed solution using regex running. Thanks for the imperfect alternative, which works perfectly for my need.
