How to Use the CSV Column Mapper Tool
🗺️ Open the CSV Column Mapper and follow along with this tutorial.
Open Tool →Steps
Step 1: Upload Your CSV
Click Upload CSV in the toolbar. The tool parses your file and lists all detected column headers.
Step 2: Review the Column List
The column list shows each header from your source file. Each row has a drag handle for reordering, a text field for renaming, and a checkbox for inclusion.
Step 3: Reorder Columns
Click and drag any column row by its handle to move it to a new position. The output will use the columns in the order shown in this list.
Step 4: Rename Headers
Click into any header name field and type the new name you want in the output. The source data is not affected — only the output header changes.
Step 5: Exclude Columns
Uncheck the checkbox next to any column you do not want in the output. Excluded columns are visually dimmed and will not appear in the exported file.
Step 6: Preview the Mapped Output
Click Preview to see the first rows of the mapped output. Confirm the column order, header names, and that excluded columns are absent.
Step 7: Export the Mapped CSV
Click Export Mapped CSV to download the remapped file. The output contains the selected columns in the order you set, with the header names you specified.
