About the CSV Column Extractor
Extract one or more CSV columns by name. It is useful when data needs to move between spreadsheets, APIs, configuration files, databases, or documentation without retyping records.
The extractor selects only the requested information; review the result before discarding the original source.
How to use it
- Paste CSV (add a second line: Columns: name,email) in the input pane. Use the example button if you want to see the expected syntax.
- Review the input for the structure shown in the example. Then select “Extract columns.”
- Inspect the result for warnings or structural differences, then copy it into the destination system.
Practical example

Try this sample input: name,email,role Avery,avery@example.com,Admin Columns: name,email Select “Extract columns” and compare the result with the source before using it elsewhere.
What to know about the result
