Hello everyone,
I can’t read every PDF files with OCR using For Each File In Folder activity.
The problem is keep reading only 1 PDF file which is chosen in READ PDF WITH OCR activity.
How do I fix this? Please help.

Temuulen

I think I need first page of every pdf files so the Range of Read PDF With OCR must be 1 right?
You are using Both Scanned and Normal PDF’s in One Folder so try like this
Take the output of Read PDF with OCR activity if length<0 means it is normal pdf so it goes to extract Read PDF Text activity.
I hope it helps!!

If the pdf file name is specific that you want to read then we will write a condition
Inside for each file in folder, Place If condition activity in that activity write the below condition
CurrentFile.Name.eqauls("Give the specific pdf file name here")
In then block give the Read PDF with OCR activity.
In else block give only Read PDF activity.
Give the same variable to the Output for both activities then the output will be same.
If we give if condition when the required pdf file comes it will go to Read PDF with OCR activity.
Hope it helps!!

Hi,
Sorry, I haven’t tried yet.
A sec
It did work!
I’ve tried on new PDF files and I works.
It seems the old pdf files were cannot be scanned I guess.
Thanks all
Hi,
Can you share your old pdf by image?
For each file in folder, if it is PDF, robot will read all .
