Enter exact header names one per line to keep only those columns and arrange them in the requested order.
Inputs are limited to 1 MiB, 10,000 rows, and 256 columns.
Nothing is placed in a URL, account, or remote log.
Strict, bounded, local processing
Selection is explicit and case-sensitive, so a missing or misspelled header produces an error instead of silently dropping data.
Each requested name must match one unique header. The engine maps those positions for every row and emits a new table containing only the selection.
Listing names also makes reordering explicit: put status before name to produce that order.
Other retained fields may still identify a person or reveal sensitive attributes. Review the resulting dataset and its destination before sharing it.
