THE PROBLEM
How do I extract columns from a CSV file?
Exports often contain dozens of fields when an import, report, or colleague needs only a few. Deleting columns manually is slow and can accidentally reorder rows or alter identifiers.
- Cell values are not trimmed, reformatted, deduplicated, or type-converted.
- Rows are not filtered or sorted.
- The original wide CSV remains unchanged.
HOW IT WORKS
Clear changes, no hidden guesses
Choose by heading
Each checkbox includes its column number so blank or repeated headings remain unambiguous.
Row order is preserved
The extractor copies cells across each row without sorting or filtering records.
Missing cells stay empty
If a short row lacks a selected column, the output contains an empty cell instead of shifting data.
