About JSON & Data
Format, validate and convert structured data — JSON, CSV, YAML, XML, .properties and .env files — without pasting it into an unknown backend. Everything here parses locally in your browser, so API responses containing keys, tokens or customer records stay on your machine. The formatter beautifies or minifies JSON and points at the exact spot where parsing fails; the converters move data losslessly between JSON and CSV, YAML or XML with correct quoting and escaping; the viewers turn raw CSV into a sortable table. These are the tools you reach for when an API returns a wall of minified JSON, a spreadsheet import needs clean CSV, or a config file needs translating between formats.
