Extract Every Sheet From an Excel Workbook as a CSV — Free
- For database imports, CRM uploads, or version-controlled data, CSV is the universal format — but Excel only exports one sheet at a time natively.
- Our free browser tool exports every sheet in a multi-tab workbook as a separate CSV in one click.
- Works for financial reports, customer exports, product catalogs — any multi-tab workbook where each tab is a logical table.
Table of Contents
CSV is the universal format for importing spreadsheet data into almost anything else — databases, CRMs, accounting software, Git repositories, ETL pipelines. Excel's one limitation: the native "Save As > CSV" only saves the currently active sheet. A 12-tab workbook means 12 manual saves.
Our free sheet splitter has a "Download All as CSVs" button that processes every tab in one click. Drop the workbook, hit the button, get every sheet as its own .csv.
When You Actually Want CSVs (Not Xlsx)
- Database imports. MySQL, PostgreSQL, SQL Server, BigQuery — all have bulk CSV import tooling. Xlsx imports usually require an extra conversion step.
- CRM imports. HubSpot, Salesforce, Pipedrive, Close — all prefer CSV. Xlsx uploads sometimes work but often trigger edge-case parsing bugs.
- Git version control. CSVs diff cleanly line-by-line. Xlsx files are zip archives and diff as "binary changed" — useless for reviewing what changed.
- ETL pipelines. Airflow, dbt, Fivetran — pipelines are built around CSV ingestion. Adding xlsx parsing steps adds failure modes.
- Public data publishing. Government and research data portals publish CSV because it's readable by every stats tool and programming language without a dependency.
If any of those is your downstream system, start with CSV.
What Survives XLSX-to-CSV Conversion
| Element | Survives? | Notes |
|---|---|---|
| Cell values (text, numbers) | Yes | Fully preserved |
| Formulas | No — only the computed value | CSV stores what the formula evaluated to, not the formula itself |
| Dates | As text representation | Format depends on locale; consider exporting as ISO 8601 (YYYY-MM-DD) where possible |
| Merged cells | Partially | The top-left value appears; other cells in the merge become empty |
| Charts, images | No | CSV is text-only |
| Colors, fonts, formatting | No | CSV has no styling |
| Multiple header rows | Yes | All rows preserved; consumer script needs to know where data starts |
Before bulk-exporting, decide if any of the "No" rows matter for your downstream. If they do, export as xlsx instead.
Sell Custom Apparel — We Handle Printing & Free ShippingStep-by-Step: Every Tab as a CSV
- Open the sheet splitter.
- Drop your .xlsx file (or drag it from Finder/Explorer).
- Every sheet shows up in the list.
- Click Download All as CSVs. Each sheet downloads as a separate file named after the sheet tab.
- In your Downloads folder, you now have one CSV per original sheet.
Filenames: the tool uses the sheet's tab name as the CSV filename. If your sheets are named "January Sales," "February Sales," etc., you get January_Sales.csv, February_Sales.csv. Special characters in tab names are sanitized (spaces to underscores, etc.) so the files are safe on any OS.
Real Import Examples From Common Systems
PostgreSQL:
COPY sales FROM 'January_Sales.csv' WITH (FORMAT CSV, HEADER);HubSpot contact import: Upload January_Contacts.csv through Contacts > Import. Map columns to HubSpot properties on the second screen.
WooCommerce product import: Products > All Products > Import. Drop the product CSV.
Git-tracked analytics data: Commit the CSVs; every future PR shows row-by-row diffs of what changed.
For all of these, a multi-tab Excel workbook is the wrong starting point — the consumer expects one CSV per table. The bulk export makes the conversion one click.
Where This Approach Isn't the Right Tool
- If you need CSVs split by row count, this tool splits by sheet, not by row. Use Python's pandas or command-line
splitfor row-based chunking. - If you need CSVs split by column value (one CSV per region, one CSV per customer), that's a different operation. This tool splits the workbook as-is; it doesn't regroup a single sheet.
- If your xlsx has cross-sheet formulas, the computed values are preserved in the CSVs — but the relationships between sheets are lost. Export as xlsx if cross-sheet logic matters.
- If you're targeting a system that needs a specific CSV dialect (semicolon delimiter, UTF-16, specific date format), you may need to post-process the CSVs. Our tool outputs standard comma-delimited UTF-8.

Open Free Sheet SplitterFrequently Asked Questions
Does the CSV include the header row?
Yes — the first row of each sheet becomes the first row of its CSV. If your data doesn't have a header row, the first data row ends up labeled as headers; add an empty header row before export if that's a problem.
What about commas inside cell values?
Values containing commas, quotes, or newlines are automatically quoted per the CSV standard (RFC 4180). Any CSV parser follows the same rules.
Can I get just one sheet as a CSV?
Yes — instead of "Download All as CSVs," click the individual sheet's CSV button. Only that sheet downloads.
Will this handle very wide sheets (many columns)?
Yes. CSV has no column limit. Sheets with hundreds of columns export correctly; the tool tests with real-world sheets up to ~500 columns.
Is UTF-8 encoded? What about non-English characters?
Yes — output is UTF-8 encoded. Chinese, Japanese, Arabic, Hebrew, Hindi, Cyrillic, emoji — all preserved. If you're importing into a system that expects a different encoding, convert after export with iconv or similar.
