Why use this tool

Why Use a CSV Sorter?

Sorting CSV by column helps you organize exports, put names in order, or sort numbers and dates correctly. An online CSV sorter lets you do this without installing software or uploading files to a server.

Sort by any column

Choose which column to sort by—name, date, number, or any other field.

Numbers and dates sorted correctly

Treat values as numbers or dates so 10 comes after 2 and dates sort chronologically.

Ready for Excel or Sheets

Download sorted CSV that opens correctly in spreadsheets and other tools.

Private and fast

Sorting runs in your browser; your data never leaves your device.

FAQ

Frequently asked questions

What does this CSV sorter do?

It sorts the rows of your CSV by a column you choose. You can sort ascending or descending and treat values as text, numbers, or dates. The header row stays at the top.

Can I sort by any column?

Yes. After you paste or upload CSV, a dropdown lists all columns (from the header or as Column 1, Column 2, etc.). Choose the column you want to sort by.

Can I sort numbers correctly instead of alphabetically?

Yes. Choose “Number” under “Treat values as” to sort numerically (e.g. 2, 10, 100). Use “Date” for date strings, or “Auto-detect” to let the tool guess.

Does this work with quoted CSV values?

Yes. The parser correctly handles values in double quotes, commas inside quotes, and escaped quotes, so your sorted output remains valid CSV.

Are my files uploaded anywhere?

No. Everything runs locally in your browser. Your CSV is never sent to a server.

Is this tool free?

Yes. The CSV sorter is free to use with no signup required.

Can I use the output in Excel or Google Sheets?

Yes. The generated CSV works in Excel, Google Sheets, and other spreadsheet tools.
