How it works
Add your workbook
Drop an .xlsx, .xls or .ods file. Every sheet appears as a tab with a live preview.
Choose the format
Comma, semicolon or tab; UTF-8, or UTF-8 with BOM so Excel reopens accents correctly; values as shown or raw.
Download
One sheet as a .csv file, or every sheet at once in a ZIP.
Frequently asked questions
Is my spreadsheet uploaded?
No. The workbook is read entirely in your browser and nothing is sent anywhere — which matters for payrolls, customer lists and anything else you would not hand to a website.
What happens with several sheets?
A CSV file holds one table, so each sheet becomes its own CSV. Pick the sheet you want, or download all of them together in a ZIP. Hidden sheets are listed too, and marked as hidden.
Will dates and numbers look the way they do in Excel?
"As shown" writes exactly the text Excel displays — 15/03/2024, 1,234.50, 12% — which is what Excel's own Save As CSV does. "Raw values" writes plain numbers and ISO 8601 dates such as 2024-03-15, which databases and code read without guessing.
Why does my CSV show strange characters when I open it in Excel?
Excel reads a CSV in your computer's old regional encoding unless the file starts with a byte-order mark. Choose "UTF-8 with BOM" and accents, Cyrillic, Arabic, Chinese and emoji open correctly. Plain UTF-8 is the better choice for databases and programming.
Comma or semicolon?
In countries that write decimals with a comma — most of Europe and South America — Excel expects semicolons between fields. Choose semicolon for those, comma everywhere else, or tab when your data is full of both.
What about formulas, merged cells and hidden rows?
Formulas are written as their calculated results. A merged cell keeps its value in its first cell, or can be repeated into every cell of the merge. Hidden rows and columns are included unless you choose to leave them out.
Good to know: CSV stores values only — cell formatting, formulas, charts and images are not part of the format. Password-protected workbooks must have their password removed first.
