AboutRename Cols
Bulk rename headers and convert to snake_case for SQL.Category: Cleaning & PreparationPreparing a CSV for import into a SQL database that rejects spaces or special characters in column namesStandardizing header naming conventions across files from different departmentsRenaming a single ambiguous header like "Value" to something descriptive before sharing a file
The Rename Cols tool is compatible with:.Run Rename Columns after Trim & Sanitize so you're working with clean structure, then use Schema Detect to validate the resulting column types before importing into a database.Rename Columns lets you bulk-edit every header in one pass instead of clicking into each cell individually. It can auto-convert headers to snake_case (customer_name instead of "Customer Name"), strip special characters that break SQL column names, and apply find-and-replace patterns across all headers at once.
Frequently Asked Questions:
Does it only rename, or can it reformat too?
Both, it bulk-renames headers and can convert them to snake_case, which is the format most SQL databases expect.
Can I rename just one column instead of all of them?
Yes, you control which headers get renamed and to what.
Useful for developers and analysts pushing CSV exports into databases or APIs that enforce strict naming rules.
