Sort a CSV or Excel file by any column, keep only the rows that match a condition, and remove duplicates based on a single column — all in your browser. The result updates live and downloads as CSV or Excel. Your data is processed on your device and never uploaded.

Handy for ordering a list, pulling out just the rows you care about, or keeping one row per customer or ID.

How to sort and filter a csv

  3. Download the result as CSV or Excel.

Frequently asked questions

Can it sort numbers correctly?

Yes — when a column is all numbers it sorts numerically; otherwise it sorts as text (A→Z).

How is "remove duplicates by column" different from Clean CSV?

Clean CSV removes rows that are identical across every column. Here you keep the first row for each unique value in one chosen column.

Is my file uploaded?

No. Sorting, filtering and de-duplication all happen in your browser.
