Separate Excel Tabs Into Individual Files (Free Browser Tool)
- Drop your .xlsx into our tool — every tab becomes a separate downloadable file.
- Download each sheet individually as .xlsx or .csv, or grab all sheets at once.
- No VBA, no Python, no Power Automate flow, no account. File never leaves your browser.

The fastest way to turn every tab in an Excel workbook into its own file is a browser tool that reads the workbook, lists every sheet, and gives you a download button per sheet. Our free sheet splitter does exactly that — drag in a .xlsx, see every tab, click to download. No VBA macro, no Python pandas script, no Power Automate flow, and no upload to anyone's server.
This post covers the capability gap most tutorials skip: what you can and can't split with this approach, the three fastest download modes, and when to use CSV vs. XLSX output.
How It Works — 4 Clicks
- Open the sheet splitter.
- Drag your multi-tab .xlsx (or .xls or .ods) file onto the drop zone — or click to browse.
- Every sheet appears in a list with its row count.
- Click to download each sheet as .xlsx or .csv, or hit "Download All as CSVs" / "Download All as .xlsx" for a bulk grab.
The whole operation runs inside your browser. No file is uploaded, no account required, nothing is logged. Close the tab and nothing of your data remains anywhere.
What "Splitting" Means Here (And What It Doesn't)
This tool splits a workbook by sheet. One sheet in, one file out. If your source workbook has a January tab, a February tab, and a March tab — you get January.xlsx, February.xlsx, March.xlsx.
It does not:
- Split a single sheet into chunks by row count (that's a different operation — see the FAQ)
- Split a single sheet into multiple files by column value (e.g., one file per Region). That needs VBA, Power Query, or Python.
- Split a CSV. CSVs don't have tabs, so the "split by sheet" model doesn't apply.
If you need any of those, this tool isn't the right one. For what it is built for — multi-tab Excel to individual files — it's the fastest free option.

The tool offers both. Pick based on where the files are going.
| Output format | Best for | Downsides |
|---|---|---|
| .xlsx | Keeping formulas, formatting, charts, merged cells. Opens identically in Excel. | Larger files. Not portable to non-spreadsheet tools. |
| .csv | Imports into databases, CRMs, accounting software. Smaller, universally readable. | Loses formulas, formatting, colors, charts. Only the raw values remain. |
Rule of thumb: if the next step is another spreadsheet tool, use .xlsx. If the next step is any other system (SQL import, HubSpot, QuickBooks, WooCommerce), use .csv.
The Three Most Common Reasons People Split Workbooks
- Monthly reports stored as tabs. Someone built a "2026.xlsx" with a tab per month. Now you need to email January to one stakeholder and February to another. Splitting lets you send only the relevant file.
- Region-per-tab or client-per-tab. A sales tracker with a tab per region, or an agency file with a tab per client. Splitting delivers each stakeholder only their own data, without exposing the others.
- Importing into another system. Most import tools (HubSpot, Salesforce, WooCommerce, Shopify) expect one file per "thing." A multi-tab workbook with customer segments needs to become one CSV per segment before import.
For all three, the free tool takes 10 seconds. VBA or Python scripts take an hour to write, test, and maintain.
The File Never Leaves Your Browser
This matters for finance, HR, and healthcare workbooks. Uploading a payroll workbook or a patient appointment schedule to a random online splitter is a compliance red flag. Our tool processes the file entirely in your browser tab — the bytes are read by JavaScript running on your machine, split into separate workbook files, and passed back to you as downloads. No server ever sees the data.
Close the browser tab when you're done and nothing persists.

Open Free Sheet SplitterFrequently Asked Questions
What if I need to split a sheet by row count (e.g., every 10,000 rows)?
Our tool doesn't do that — it splits by sheet, not by row count. For row-based splitting, use Python's pandas or the command-line split utility, or manually copy row ranges into new sheets and then split with this tool.
Does this work on .xls (old format) as well as .xlsx?
Yes — the tool accepts .xlsx, .xls, and .ods (LibreOffice/OpenOffice) files.
Can I split a workbook with 50+ tabs?
Yes. Performance is fine up to several hundred tabs. Very large workbooks with heavy formatting may take a few seconds to parse. Everything stays in the browser.
Will formulas survive the split?
Formulas that reference only cells within the same sheet survive. Cross-sheet formulas (e.g., '=Feb!B2') will break because the other sheet is now a separate file. For cross-tab dependencies, consider keeping the workbook whole.
Can I split Google Sheets with this?
Not directly — export your Google Sheet as .xlsx (File > Download > Microsoft Excel), then drop it into the tool.
