Frequently Asked Questions

Can I extract data from scanned PDF reports for Tableau?

Yes, the AI uses OCR technology to extract data from scanned PDFs and document images, converting them to structured Excel or CSV files for Tableau Prep.

How do I handle multiple PDF files with the same data structure?

Use batch processing to upload multiple PDFs at once. The system will extract the same field types from each document and compile them into a single structured spreadsheet.

What file formats work best with Tableau Prep after extraction?

Excel (.xlsx) and CSV files work directly with Tableau Prep. The extraction creates clean column headers and consistent data formatting for smooth import.

Can I customize which data fields get extracted from my PDFs?

Yes, you can select specific fields to extract based on your Tableau visualization needs, creating focused datasets rather than extracting all available data.
