Large Spreadsheets, Solved
When a spreadsheet exceeds 100,000 rows, everything gets harder. Excel freezes, Google Sheets hits its cell limit, and importing into CRMs fails. Splitting into smaller files is the practical solution.
Our tool handles CSV, XLS, and XLSX files. Set a row limit per output file, and the splitter creates perfectly chunked files with headers intact. Every chunk is ready for immediate use — no cleanup required.
All processing happens in your browser. Whether it's payroll data, customer records, or inventory lists, your files stay private on your device.
