Data & JSON tools
Format JSON, or convert CSV, spreadsheet paste, and Markdown tables. See the data clearly, then export.
Local only · no upload · nothing stored JSON format & validatePretty-print, minify, or check valid JSON. CSV cleanerTrim, remove blank rows, deduplicate, sort, select and reorder columns. TSV ↔ CSVFast spreadsheet tab-separated data and CSV conversion. JSON Flatten / UnflattenRFC 6901 JSON Pointer path maps with collision and unsafe-path checks. CSV ↔ YAMLCSV records and flat YAML object lists using the shared pinned YAML parser. CSV ↔ JSONChoose delimiter and file encoding; keep text and leading zeros by default. CSV export can guard against formula injection. Table ↔ MarkdownTurn Excel / spreadsheet paste into Markdown, or back into TSV you can paste into a sheet. JSON → tableTurn a JSON array into tabular data you can preview, copy, and download.
Why not guess types by default?
Product codes, postal codes, and IDs often have leading zeros. CSV → JSON treats everything as text by default; turn on type inference only when you need numbers or booleans.
