How to Split a Spreadsheet Into Multiple Files Free

Why Split a Spreadsheet?

Your CSV has 500,000 rows but the import tool accepts 10,000 at a time. Your Excel report covers all regions but each manager needs only their data. A client sent one massive file that needs to be divided by category, date, or department. Splitting by hand means hours of copying rows. Automated splitting takes seconds.

How to Split a Spreadsheet

1. Open the Split Spreadsheet tool
2. Upload your CSV or Excel file
3. Choose how to split: by row count (e.g., every 1,000 rows) or by column value (e.g., split by "Region")
4. Download the resulting files

All processing happens locally in your browser. Your data stays on your device.

Split by Row Count vs. Column Value

• By row count — divides the file into equal chunks. Perfect for breaking up large files for batch imports or processing limits.
• By column value — creates one file per unique value in a column. Split a sales report by "State" and get 50 separate files. Split by "Month" and get 12 files.
