Excel Splitter
Split an Excel workbook into separate files, one per sheet.
Break a multi-sheet Excel workbook into individual .xlsx files, one per sheet, bundled into a ZIP for download. Useful when you need to share or process one sheet from a larger workbook without sending the whole file.
- Files never leave your device
- Runs entirely in your browser
- Free, no account needed
How to use Excel Splitter
Two steps, and nothing to install.
Drop your workbook
Add the .xlsx file. It is parsed locally, so confidential data stays on your device.
Download the ZIP
Save the archive containing one .xlsx file per sheet, each named after its tab.
More free tools
Free, private, and no sign-up on any of them.
How this works in your browser
A JavaScript spreadsheet library parses the workbook in your browser, reading its internal structure to enumerate the sheets and their cell contents. Each sheet is then written into a brand new single-sheet workbook and encoded as its own .xlsx file, and the whole set is packed into a ZIP assembled in memory before being handed to you as one download. Because each output is a freshly constructed workbook rather than a copy of the original with sheets deleted, cross-sheet formulas have nothing to resolve against, which is the honest reason those references break. Nothing is uploaded at any stage, which is what makes this usable on data you could not send to an online converter.

Frequently asked questions
What it can and cannot do, and what happens to your files.
What happens to formulas that reference other sheets?
Formulas that reference cells on a different sheet will break once that sheet is split into a separate file, since the reference no longer resolves. Values computed before splitting are preserved as static results where the source uses simple formulas.
How many sheets can I split at once?
There is no hard limit. Every sheet in the workbook becomes its own file.
What format are the split files?
Each output file is a standard .xlsx spreadsheet.
Are the split files named after the sheets?
Yes, each file takes its name from the sheet tab it came from, so a workbook with tabs for each region or month produces files you can identify without opening them.
What should I check before splitting?
Cross-sheet references, chiefly. If your summary tab pulls totals from the monthly tabs, those links cannot survive separation into different files. Converting formulas to values first, using paste special in Excel, is the reliable way to keep the numbers you care about.
Is my spreadsheet uploaded anywhere?
No, and for financial or HR data this is the point. The workbook is parsed and the output files are written inside your browser tab, so payroll, client lists and internal figures never reach a server.
Why is everything bundled into a ZIP?
Because a browser cannot reliably trigger a dozen separate downloads without being blocked as suspicious. One archive is both more predictable and easier to keep organised.
