Excel to CSV Converter (Copy & Paste)
Paste cells copied from Excel or Google Sheets and get clean CSV text. Commas inside cells are quoted automatically. Nothing is uploaded.
What This Calculator Tells You
This tool converts rows copied from Excel, Google Sheets or Numbers into clean CSV text. Select the cells in your spreadsheet, copy, paste them here, and you get comma-separated output ready for an import screen, a database or a script.
It works by copy and paste rather than file upload, which means nothing leaves your browser and it works the same for .xlsx, .xls and Google Sheets.
What to Enter
- Pasted rows β when you copy cells from a spreadsheet, columns are separated by tabs and rows by line breaks. Paste them directly; include the header row if you want one in the CSV.
Worked Examples
1. Importing contacts into a CRM
Copy columns Name, Email and Company from Excel and paste them in.
- The output is a CSV you can paste into a .csv file or straight into an importer that accepts CSV text.
2. Values that contain commas
A cell holds Austin, TX.
- The converter wraps that cell in double quotes, so the comma does not create a new column.
3. One tab from a multi-sheet workbook
Copy only the sheet or range you need instead of exporting the whole file.
- Paste, convert, and save the result with a .csv extension.
How to Read Your Result
- Each pasted line becomes one CSV row; each tab becomes a comma.
- Cells containing commas are quoted automatically.
- Formulas are not copied β spreadsheets paste their displayed values, which is usually what an import needs.
Common Mistakes to Avoid
- Copying merged cells, which can shift columns. Unmerge first.
- Hidden columns are still copied in some apps; delete them first if you do not want them.
- Number formatting β currency symbols and thousands separators are copied as displayed. Format cells as plain numbers before copying if your import expects raw values.
When to Use This Calculator
- Prepare CSV files for CRM, email and e-commerce imports.
- Move a range from a large workbook without exporting the whole file.
- Create CSV text for scripts and databases.
- Convert Google Sheets ranges without downloading.
Frequently Asked Questions
Can I upload an .xlsx file?
Not at the moment. Copy the cells from the workbook and paste them β the result is the same, and your file never leaves your computer.
Will formulas be kept?
No. CSV stores values only, and spreadsheets paste displayed values.
What about non-English characters?
They are preserved as pasted. Save the final file as UTF-8 when your import asks.
How do I turn the CSV into JSON?
Use the CSV to JSON converter.
Do you store the values I enter?
No. All calculations happen in your browser. Your data never leaves your device.
