What does the Split Excel Files do?
Free Excel splitter — split one large spreadsheet into multiple files by row count or by values in a chosen column. It's part of TeckForge's excel tools collection, sitting alongside related tools you can reach from the sidebar.
How to use the Split Excel Files
- Open the Split Excel Files — works with .xlsx, .xls, and .csv files.
- Upload the spreadsheet (or spreadsheets) you're working with.
- Let the tool do its work, then check the results in the preview.
- Download the updated spreadsheet file.
Tips for getting a good result
- Save a backup copy of your original spreadsheet before running a bulk edit, just in case you want to re-run it with different settings.
- If a formula-heavy sheet looks off after processing, check whether the tool recalculates formulas or preserves the last saved values.
- Very wide spreadsheets can be easier to review by scrolling the result preview horizontally before downloading.
Frequently asked questions
Does it support both Excel and CSV files?
Yes, the Split Excel Files works with .xlsx, .xls, and .csv formats.
Is my spreadsheet data private?
Yes — the Split Excel Files processes everything in your browser tab; your data is never uploaded to a server.
Can it handle multi-sheet workbooks?
Where relevant, the tool reads every sheet in the workbook — check the tool's own preview to see which sheets were detected.
What happens to charts or images embedded in the sheet?
Support varies by tool and task — check the output preview, since some transformations focus purely on cell data rather than embedded objects.
