TabularRename CSV Column Headers
Rename any column header in your CSV or XLSX file. Map old names to new ones before importing to another system.
Pro feature

See Pro plansWhat this tool does
Column names from exports rarely match what your target system expects. Tabular lets you rename headers in bulk — enter the new name for each column and download a file that's ready to import. No manual editing of the header row required.
Problems it solves
- Mapping CRM export headers to database column names
- Standardizing column names across multiple data sources
- Removing spaces or special characters from headers
- Renaming columns to match an API's expected field names
- Localizing column names for international teams
Example
Three columns renamed to snake_case for database import.
Before
| First Name | Email Address | Created At |

| Bob | bob@example.com | 2024-01-16 |
After
| first_name | created_at | |
| Alice | alice@example.com | 2024-01-15 |
| Bob | bob@example.com | 2024-01-16 |
Frequently asked questions
Can I rename all columns at once?
Yes. Every column in your file is shown with an input field. Fill in only the columns you want to rename — leave the rest blank to keep the original name.
What happens to the row data?
Nothing. Only the header row is changed. All data rows remain exactly as they were.
Can two columns end up with the same name?
You can set duplicate names, but this may cause issues when the file is imported. We recommend keeping all column names unique.
Is this a Pro feature?
Yes. Column renaming is available on Pro and Business plans.
