CSV Column Mapping Builder

Map source columns to user-defined destination headings while preserving cell strings.

Enter your values

Your inputs are processed locally. Review the method and limitations before relying on the estimate.

First row must contain these exact column names: sku, price. Your text stays in this browser. Export JSON/CSV for your own backup; no automatic cloud saving.

For the second input table, type exactly ---SECOND--- on its own line after your first CSV table, then add the second CSV table including its header row (as shown in the example).

Local save is optional and stays on this device; do not save sensitive information on shared devices.
