CSV Formatter & Converter
Paste CSV or TSV data to normalise delimiters, trim whitespace, skip empty rows, and export as JSON — all running locally in your browser.
Formatting options
- Delimiter — choose comma, semicolon, tab, pipe, or auto-detect.
- Has Header — treat the first row as column names.
- Trim Whitespace — remove leading/trailing spaces from every field.
- Skip Empty Rows — omit rows where all fields are blank.
CSV → JSON
Switch to the CSV → JSON tab to convert your data into a JSON array of objects (when Has Header is enabled) or a 2-D array of strings. The output is formatted with 2-space indentation and is ready to paste into any code editor.
