How to use Sort CSV Columns
- 1. Paste the CSV. Enter the rows in the input pane. Whole records are kept together during sorting, so every value stays attached to its original row while the rows change order.
- 2. Choose the sort key. 'Sort by column (name or number)' takes a header name like age or a 1-based position. With First row is header checked, the header stays pinned at the top while data rows sort beneath it.
- 3. Set comparison and direction. Compare as Text sorts alphabetically, where 10 lands before 9; Compare as Numbers sorts by value, where 9 precedes 10. Tick Descending to reverse either ordering, useful for largest-first rankings.
- 4. Copy the ordered file. Copy the sorted result. Check the top and bottom rows against your expectation; if 100 sorted before 20, you are in text mode and should switch to Numbers.
When to use Sort CSV Columns
Sort CSV Columns reorders the rows of a file by any column, treating values as text or as numbers. It replaces the open-in-Excel, select-all, data-sort ritual with a paste and two settings, and unlike a naive line sort it never separates a value from the rest of its record.
- Ranking rows by a numeric metric. A load-test export has a latency_ms column and you want the slowest requests first. Sort by that column as Numbers, descending, and the worst offenders float to the top.
- Ordering an export for review. A stakeholder wants the customer list alphabetized by surname before a meeting. Sorting by the name column as Text produces the ordering in seconds, header row still on top.
- Stabilizing files for diffing. Two exports of the same table arrive with rows in arbitrary order, so diff shows everything changed. Sorting both by the id column makes the real differences visible.
Examples
