Modufile's PDF to Excel tool extracts tabular data from PDFs and generates .xlsx spreadsheet files. It uses MuPDF to extract text blocks with precise position coordinates, then applies column detection based on X-coordinate clustering to reconstruct the original table structure. The resulting spreadsheet is built using SheetJS (xlsx library). This tool works best with PDFs containing clearly structured tables with consistent column alignment — such as financial statements, invoices, reports, and data exports. The entire process runs in your browser, so your files are never sent to a server.
