How do I translate a CSV file online?
Upload your CSV file to ForgeFile, select your target language, and click Translate. Our AI identifies text columns and translates them while preserving all data structure, quoting rules, and delimiters.
Are column headers and structure preserved?
Absolutely. ForgeFile preserves every column position, header, row order, and delimiter. Your translated CSV imports into any database or analytics tool.

What delimiters are supported?
ForgeFile auto-detects and preserves comma, semicolon, tab, and pipe delimiters. The output matches your original file's delimiter format exactly.
Can I choose which columns to translate?
Yes. You can select specific columns for translation and exclude others - ideal for product feeds where only titles and descriptions need localization.
Is there a file size limit?
For larger files or automated data pipelines, contact us about enterprise plans with API access and higher limits. The maximum file size depends on your plan.
Is my CSV data secure during translation?
