As per the description above, you are getting a garbled text when you convert a PDF file to Excel, Is that correct?
Please try to convert the PDF files using the URL https://cloud.acrobat.com/exportpdf and check if it makes any difference.
Try to Export another PDF and check. You may also refer to Text is garbled in converted file | ExportPDF Link: https://helpx.adobe.com/acrobat-com/kb/troubleshoot-conversion-problems.html
Let us know how it goes.
Thanks for your response. I tried to convert a file using https://cloud.acrobat.com/exportpdf. It makes no difference.
I converted around 150 documents, they all share the same structure. I get only minor issues with the text, but significant issues (i.e. more than i can fix with a manual Quality assurance step) with (nested) tables.
I am also having problems converting my PDF to Excel. Some values are missing, items are not in their original columns and sometimes multiple rows have been converted into one. It is unusable like that.
