JSON ↔ CSV

Powered by PapaParse, the most-used CSV parser on npm. Handles RFC 4180 edge cases (embedded commas, quote escaping, multi-line fields). Picks delimiter via the dropdown — Excel exports often use semicolons in EU locales.

What if my JSON has nested objects?

CSV is flat, so nested objects flatten poorly. The converter only handles arrays of flat objects. For nested data, flatten first (e.g., JSONPath) or use a different export format.

Why are quotes appearing around values that don't need them?

CSV quotes any value containing the delimiter, a quote, or a newline. PapaParse follows RFC 4180. To force always-quote or never-quote, use the npm library directly with config.

TSV (tab-separated)?

Yes — switch the delimiter dropdown to "tab".

Header row required for CSV → JSON?

Yes. The first row becomes property names. Without a header row, use the npm library with header: false to get arrays of arrays.

• JSON Formatter / Minifier / Validator

  Pretty-print, minify, or validate JSON. Strict spec — catches trailing commas, unquoted keys, comments at the source.

• JSON ↔ YAML

  Convert between JSON and YAML losslessly, preserving scalar types and structure.

• JSONPath Playground

  Test JSONPath queries against a sample document — recursive descent, filters, wildcards.
