Convert delimited text or JSON into CSV, TSV, Markdown and JSON tables.
Use and export
Paste text, load a UTF-8 file or try the sample.
Choose options and select Run. Review the result, counts and any warnings.
Copy or download the result in an available format. Run again after changing inputs.
Methods and limits
Up to 2,000 rows and 30 columns. Accepts JSON arrays of objects, arrays or scalar values, and quoted comma/tab/semicolon/pipe-delimited text. Headings must be unique for JSON export. Short rows are padded. JSON object values become strings; nested values are JSON-encoded. CSV formula protection can alter formula-like cells and is enabled by default.
Private processing
Text and files stay in browser memory and a local worker. No uploads, account access, network lookups or automatic storage. Refreshing clears your work. Input is limited to 500 KB and generated output to 1 MB; processing times out after five seconds. Downloads and clipboard copies contain the output you choose.
