Key Features
Smart Table Detection
Automatically detect data tables in your PDF documents using intelligent text grouping algorithms. Identifies column and row structures based on text position analysis.
Multiple Output Formats
Export detected tables in your preferred format: JSON for data processing, Markdown for documentation, or CSV for spreadsheet applications.
Flexible Configuration
Adjust minimum columns and rows thresholds to control table detection sensitivity. Lower values catch more potential tables, higher values filter out noise.

All processing happens locally in your browser using PDF.js. Your PDF files never leave your device — no uploads to any server, complete privacy.
No Installation Required
No software to download or install. The entire extraction engine runs in your browser — works on any device with a modern browser.
About This PDF Table Extractor
Our PDF Table Extractor uses PDF.js for text extraction and a custom table detection algorithm based on text position analysis. It groups text items by their Y coordinates to identify rows, then analyzes column positions to detect table structures. Multiple PDFs can be uploaded and processed in batch — they begin extracting automatically after upload. Each completed file appears in the results list for individual download, or all files can be downloaded together as a ZIP archive. You can adjust detection sensitivity through minimum columns and rows settings. Detected tables can be exported as JSON (structured with headers and row objects), Markdown (formatted tables), or CSV (compatible with Excel and spreadsheets). All processing stays local in your browser — no data is ever uploaded.

Extracting tables from a PDF with our tool is simple:
Upload Your PDFs
Drag and drop one or more PDF files onto the upload area, or click to browse and select files from your device.
Configure Options
Choose your preferred output format (JSON, Markdown, or CSV). Adjust minimum columns and rows thresholds to control table detection sensitivity.
Download Results
Files begin extracting automatically after upload. Each completed file appears in the results list for individual download. Use Download All to package all files into a single ZIP archive.
Important Notes
This tool detects tables by analyzing text positions in the PDF. It works best on PDFs with clearly structured text-based tables. Multiple PDFs can be uploaded and processed in batch — each completed file appears in the results list for individual download, or download all as a ZIP archive. Scanned PDFs (image-based documents) cannot be processed since they lack selectable text. Complex table layouts with merged cells, irregular spacing, or borderless designs may not be perfectly detected. Adjust the minimum columns and rows settings if tables are not being detected or if too much noise is being captured.
