How to use

Paste or import CSV, TSV, JSON row arrays or JSON object arrays. Object keys become headers; numeric literals keep their original precision. Markdown and ASCII support alignment, and ASCII uses Unicode display widths. Exported HTML escapes cell contents. Limits: 200 rows including headers, 50 columns, 4096 characters per cell and 8 MB output.
