Translate CSV Files at Scale

Column structure preserved. Quoted fields handled. Multi-line values intact. Thousands of rows translated in minutes, not days.

Spreadsheet Translation Is Tedious and Error-Prone

You export your translations to CSV, open it in Excel, manually translate row by row, fight with encoding issues, accidentally break quoted fields, and then spend an hour fixing column alignment. Multiply that by every target language.

Character encoding breaks when opening CSV in spreadsheet apps. Special characters become garbled.

Quoted fields with commas, newlines, or special characters get corrupted during translation

Column mapping gets lost. Keys end up in value columns, values in key columns.

Hundreds or thousands of rows take days to translate manually, and consistency suffers
