Frequently Asked Questions
How do I identify which PDF version contains the most recent data?
Check document metadata, creation dates, and version numbers in filenames or headers. Create a consistent naming convention like 'contract_v1.2_2024.pdf' to track revisions clearly.
Can I extract data from multiple PDF versions simultaneously?
Yes, using batch processing you can extract data from all versions at once, then compare the results in separate spreadsheet tabs or columns tagged with version identifiers.
What's the best way to compare extracted data between document versions?
Export each version to separate Excel sheets, then use spreadsheet comparison tools or create a master sheet with version columns to identify changes in key data fields.
How do I prevent mixing data from different document versions?
Use clear file naming conventions, separate folder structures for each version, and always include version identifiers in your extracted data columns to maintain clear audit trails.
