How does table detection work on complex documents?

The extractor analyzes text positioning, spacing patterns, ruling lines, and column alignment to identify table structures. It works best with tables that have consistent column spacing or visible borders. Documents with multiple tables on a single page are handled by detecting separate table regions independently.

Can it handle tables without visible borders?

Yes. The tool uses column alignment analysis in addition to border detection. Even tables rendered without gridlines can be detected if the text is consistently aligned in columns. The accuracy depends on how consistently the columns are spaced in the source PDF.

What output formats are available?

Extracted tables can be downloaded as CSV (for spreadsheets and databases), Excel (.xlsx with formatting preserved), or JSON (for programmatic use in applications and data pipelines). You can choose the format that best fits your workflow.

Does this work for scanned PDF documents?

Scanned PDFs (images without text layers) need OCR first. Use our OCR PDF tool to add a searchable text layer, then extract tables from the OCR result. PDFs with existing text layers work directly.

Extract Tables

Extract table data from PDF documents directly in your browser. Detect and extract structured tables from reports, invoices, financial statements, and research papers, outputting them as CSV, Excel, or JSON for immediate use in spreadsheets, databases, and analysis tools. The extractor uses layout analysis to identify table boundaries, columns, and rows even in complex documents. Processing runs locally via WebAssembly, keeping sensitive business and financial data private.
