How to convert PDF tables to CSV with OnyxPDF
- Drop your PDF into the tool.
- Click “Convert to CSV”.
- Download the .csv and open it in Excel, Google Sheets or LibreOffice Calc.
Why do it in your browser instead of uploading?
- No upload: the statement or report you are mining for data stays on your device.
- Free — the equivalent PDF-to-Excel conversion is a Premium feature at iLovePDF and an OCR-paid feature at CamScanner.
- Positional column detection: numbers that line up in the PDF land in the same CSV column.
- Plain CSV opens everywhere — no proprietary format, no lock-in.
Good to know (honest limits)
- Best-effort by nature: merged cells, multi-line cells and irregular layouts will need cleanup in the spreadsheet. Complex tables will not survive perfectly — no client-side converter does better.
- Scanned tables have no text layer; OCR them first, or expect empty output.
Frequently asked questions
Can I open the CSV in Excel?
Yes. CSV is the universal spreadsheet format — Excel, Google Sheets and LibreOffice Calc all open it directly. That is why this tool outputs CSV rather than a proprietary Excel file.
Why are some columns merged or split wrongly?
Columns are inferred from the horizontal positions of text on the page. Irregular spacing in the source PDF can fool the detection; a quick tidy in your spreadsheet fixes the few bad rows.
Does it work on scanned PDFs?
No — scans have no text layer. Run OCR first to get the text, then work from that.
Is my file uploaded?
No. The table extraction runs entirely in your browser.
