How to extract ( Correct and clean ) text from editable PDF ?

I am using PDF: Extract Text action to extract text from editable pdf filled by user.

When I use filled pdf to extract text it only extract labels from that pdf not values of that labels.

I used

• PDF: extract Image
• OCR: Capture image by path
• Log to file

But it is not extracting proper text from image.

problems occurs in extract text of label having check boxes as values.

what are best way to extract clean and as it is text from editable pdf/ image .

Thanks in advance
