CSV ↔ JSON
Konverter tabelldata
Om dette verktøyet
Convert between CSV and JSON, and pretty-print or filter rows. Privvert auto-detects the delimiter (comma, tab, semicolon, pipe) and correctly handles quoted fields, embedded newlines, and escaped quotes - the messy parts most naive parsers get wrong.
Useful for moving data between Excel/Google Sheets and APIs, prepping CSVs for import, debugging exports, and quickly inspecting tabular data. Everything runs locally.

Ofte stilte spørsmål
Yes - quoted fields with embedded newlines and quotes are parsed correctly per RFC 4180.
Likely a character encoding mismatch - your file may be Windows-1252 or UTF-16 instead of UTF-8. Re-save as UTF-8 from your source app.
Flat objects (one level deep) convert cleanly. Nested objects need flattening first because CSV has no concept of nesting.
Yes for CSV → JSON. For JSON → CSV, columns appear in the order keys are encountered in the first object.
Excel's CSV parser is locale-dependent: in German and most other European locales it expects a semicolon as the separator, not a comma. Save with semicolons (or use the Tab option and rename to .txt) if Excel keeps cramming everything into one column.
Yes. RFC 4180-style quoting with double-quote escaping is supported, so cells that contain commas or newlines round-trip correctly.
