About Excel to CSV
Excel to CSV opens a spreadsheet saved as .xlsx or the older .xls format and writes it back out as a plain CSV file. You reach for it when another program — a database import screen, an email or mail-merge list, an accounting or CRM system — insists on a CSV and refuses to read a native Excel workbook. Instead of digging through Excel's Save As menu, you just pick the file and download the result.
Because a CSV can only hold one flat table, the converter takes a single worksheet at a time rather than the whole workbook; if your file has several tabs, run each one through in turn. Formulas are written out as their calculated results, and styling such as cell colors, fonts, and merged cells is dropped, since a plain-text file has nowhere to keep it. What comes out is a clean grid of comma-separated values that almost any spreadsheet, database, or import tool will accept without complaint.
If you need to go the other way, remember that Excel and Google Sheets can open a CSV on their own — this tool only handles the Excel-to-CSV step, so a CSV that won't split into columns is usually fixed with Excel's Data › From Text/CSV import. The whole conversion runs inside your browser, so the spreadsheet is read on your own device and nothing is uploaded to a server. It is free, needs no sign-up, and sets no limit on how many files you convert.
Frequently asked questions
- Is the Excel to CSV converter free?
- Yes. There is no charge, no account, and no sign-up, and you can convert as many spreadsheets as you like.
- Is my spreadsheet uploaded to a server?
- No. Your Excel file is read and converted inside your browser, on your own computer, so the data never leaves your device.
- How do I convert Excel to CSV?
- Select your .xlsx or .xls file, let the tool read it, and download the CSV. There is nothing to install and no setup.
- Does it work with both .xlsx and older .xls files?
- Yes. It reads modern .xlsx workbooks as well as the older .xls format and converts either one to a comma-separated CSV. You do not need Excel installed for the conversion to work.
- My workbook has several sheets — what happens?
- A CSV file can only hold a single table, so the tool converts one worksheet into the CSV rather than the whole workbook. If you need several tabs, convert them one at a time.
- Will my formulas and formatting carry over?
- No. CSV is a plain-text list of values with no styling, so formulas come through as their calculated results. Colors, fonts, and merged cells are dropped, because the format cannot store them.
- Why convert an Excel file to CSV at all?
- CSV is the plain, universal format that databases, email and mail-merge tools, accounting packages, and CRMs ask for when they import data. Many of them reject native .xlsx or .xls files, so saving as CSV is what gets your rows accepted.
- How do I convert a CSV back to Excel?
- This tool only goes one way, from Excel to CSV. To turn a CSV into a spreadsheet, open Excel or Google Sheets and open the CSV directly, then use Save As to store it as an .xlsx file — no separate converter is needed.
- My CSV won't split into columns when I open it in Excel — how do I fix that?
- That happens when Excel guesses the wrong delimiter. Instead of double-clicking the file, open Excel and use Data › From Text/CSV, then choose the delimiter (usually a comma) so each value lands in its own column.
- Is there a limit on file size or the number of files?
- There is no cap on how many spreadsheets you can convert. Because everything runs on your own device, very large workbooks are limited only by your computer's memory rather than by any upload restriction.
