What is this tool?
This tool reformats a CSV file and produces a new CSV output directly in your browser.
It is helpful for normalizing delimiters, preparing files for specific imports, or turning CSV tables into plain text with a different separator.
How it works
- Upload the CSV file you want to reformat.
- Review the detected structure and choose the delimiter, separator, or line endings that fit your target workflow.
- Download the resulting file in the selected format.
Conversion settings
New delimiter
You can regenerate the file with commas, semicolons, tabs, or pipes so it matches the next system in your workflow.
Line endings
Choose LF or CRLF so the exported file fits your operating system and downstream tools.
Structured preview
Before exporting, you can verify how rows, columns, and headers were detected.
Common use cases
- Changing a CSV delimiter so another system can import the file successfully.
- Creating a TXT version of a CSV for manual inspection or simple sharing.
- Normalizing files before an ETL step or a legacy import process.
