Your data security is our priority. All CSV reformatting happens entirely in your browser using client-side JavaScript. Your CSV files never leave your computer or get uploaded to any server, ensuring complete privacy and security for sensitive data.

Tips for Perfect CSV Reformatting

• Always verify the input delimiter matches your source CSV file
• Use tab delimiter (TSV) when your data contains many commas
• Choose semicolon delimiter for European regional settings
• Enable "quote all fields" for maximum compatibility
• Test reformatted CSV in your target application before bulk processing
• Keep a backup of original CSV before reformatting

Frequently Asked Questions

• Does this tool change my data or only the formatting?
  The converter preserves your data values and focuses on changing delimiter, quoting, and line-ending styles. It does not attempt to transform the actual content.
• Is my CSV uploaded to a server?
  No. All CSV reformatting is done locally in your browser. Your files are not sent to any remote server.
• Can I convert CSV to TSV with this tool?
  Yes. Choose the tab (\t) option as the output delimiter to convert your CSV into tab-separated values (TSV).
• What if my CSV uses a custom delimiter?
  You can specify the correct input delimiter and then choose a different output delimiter. This lets you normalize files coming from different systems.
• Is there a file size limit?
  There is no hard limit inside the tool, but very large CSV files are constrained by your browsers memory. For huge datasets, consider processing them in smaller chunks.
