PDF to CSV free online. Extract tables and data from PDF files to CSV spreadsheet format.
About PDF To CSV
PDF to CSV extracts tabular data from PDF documents and exports it as a clean, delimiter-separated CSV file — ready for Excel, Google Sheets, or any data tool. The tool uses a combination of geometry-based table detection (column/row bounding boxes from PDF text positions) and AI-assisted header recognition to reconstruct table structure even in scanned PDFs or PDFs without explicit table tags. No server processing — table extraction runs in your browser using pdf.js for rendering and a custom column-detection algorithm. You can preview the extracted table, adjust column boundaries if the auto-detection misses a split, and download one CSV per detected table or all tables merged into a single file.
Generic PDF converters export everything as comma-separated lines with no regard for column alignment. This tool geometrically reconstructs table structure from PDF text coordinates, so column data lands in the correct CSV cell even in complex multi-column layouts. Preview mode lets you see and fix extraction before downloading — a feature missing from most online converters.
How We Compare
Compared to desktop alternatives like Adobe Acrobat Pro (starting at $19.99/month), Smallpdf ($12/month for unlimited), or iLovePDF ($9/month Premium), PDF AI Tools delivers comparable quality at $0 for the core feature set. We skip the subscription friction by processing most operations directly in your browser with WebAssembly — no server infrastructure costs to pass on to users. Our AI features (summarization, chat, OCR) use a pay-as-you-go backend that keeps your total cost well under $5/month even for power users.
How to Use PDF to CSV Free Online
- Step 1: Upload your PDF or drag it into the drop zone
- Step 2: The tool scans all pages and highlights detected tables
- Step 3: Preview the extracted data in the spreadsheet view; adjust column lines if needed
- Step 4: Choose output format (CSV, TSV) and download
Why Choose PDF AI Tools
We've built PDF AI Tools to replace expensive desktop software like Adobe Acrobat for 95% of common document workflows — at zero cost to you. Unlike competitors who gate features behind paywalls, add watermarks, or limit file sizes, our tools are genuinely free and genuinely unlimited. Your privacy matters: files processed client-side in your browser never touch our servers, and even AI-powered features use encrypted, auto-deleting processing pipelines.

Frequently Asked Questions
Can it extract tables from scanned PDFs?
Yes — scanned PDFs are OCR'd first, then the resulting text coordinates are used for column detection. Accuracy depends on scan quality.
What if the table has merged cells?
Merged cells are split into individual CSV cells with the value repeated in each spanned cell, which is the standard CSV representation.
Can I extract tables from specific pages only?
Yes — use the page range selector to target specific pages before extraction.
Is there a limit on PDF size?
Files up to 100 MB are supported. Larger files may be slow as all processing happens in your browser.
