About this Tool
Use this Column Selector to keep only the fields that belong in the final table. The interface shows all detected columns, allow reordering, hide or remove unwanted columns, and export the reduced table. It is a focused alternative to the broader Data Cleaner when the only task is choosing columns.

Frequently Asked Questions
Does selecting columns delete data immediately?
No. The tool should preview the selected view and only export the chosen columns when the user confirms.
Can columns be reordered?
Yes. Column order should be adjustable because export order often matters.
What happens to hidden columns?
Hidden columns should remain recoverable during the session until the user exports or resets the table.
What file sizes are practical in the browser?
Small and medium tables are the best fit. Very large files can use a lot of memory because parsing, previews, and exported results all live inside the browser tab.
