I am available for full-time remote positions.\n\n# Example\n\n```js\nimport guessJsonIndent from 'guess-json-indent'\n\nconst input = [{ example: true }]\nguessJsonIndent(JSON.stringify(input)) // undefined\nguessJsonIndent(JSON.stringify(input, undefined, 1)) // 1\nguessJsonIndent(JSON.stringify(input, undefined, 2)) // 2\nguessJsonIndent(JSON.stringify(input, undefined, 4)) // 4\nguessJsonIndent(JSON.stringify(input, undefined, '\\t')) // '\\t'\nguessJsonIndent(JSON.stringify(input, undefined, '\\t\\t')) // '\\t\\t'\n\n// Keep the indentation of a JSON string when parsing/serializing it\nconst jsonString = JSON.stringify(input, undefined, 2)\nconst indent = guessJsonIndent(jsonString)\nconst parsedValue = JSON.parse(jsonString)\nconsole.log(JSON.stringify(input, undefined, indent)) // Same as jsonString\n```\n\n# Install\n\n```bash\nnpm install guess-json-indent\n```\n\nThis package works in both Node.js \u003e=18.18.0 and\n[browsers](https://raw.githubusercontent.com/ehmicky/dev-tasks/main/src/browserslist).\n\nThis is an ES module. It must be loaded using\n[an `import` or `import()` statement](https://gist.github.com/sindresorhus/a39789f98801d908bbc7ff3ecc99d99c),\nnot `require()`. If TypeScript is used, it must be configured to\n[output ES modules](https://www.typescriptlang.org/docs/handbook/esm-node.html),\nnot CommonJS.\n\n# API\n\n## guessJsonIndent(jsonString)\n\nThe return value is the same as the third argument to `JSON.stringify()`:\n\n- `undefined`: none\n- integer: number of spaces\n- string: tabs\n\n# Benchmarks\n\nThis library is very fast thanks to:\n\n- Looking only at the first indented line, which is sufficient in the vast\n  majority of real-life cases\n- Being specific to JSON\n\nThe following benchmarks compares it:\n\n- With [`detect-indent`](https://github.com/sindresorhus/detect-indent),\n  [`detect-json-indent`](https://github.com/mapbox/detect-json-indent) and\n  [`detect-indentation`](https://github.com/bevry/detect-indentation)\n- On a big JSON string (8MB)\n\n```\nguess-json-indent:         43ns\ndetect-json-indent:  60114470ns\ndetect-indentation: 141975495ns\ndetect-indent:      198161087ns\n```\n\n# Related projects\n\n- [`truncate-json`](https://github.com/ehmicky/truncate-json): Truncate a JSON\n  string\n- [`is-json-value`](https://github.com/ehmicky/is-json-value): Check if a value\n  is valid JSON\n- [`safe-json-value`](https://github.com/ehmicky/safe-json-value): ⛑️ JSON\n  serialization should never fail\n\n# Support\n\nFor any question, _don't hesitate_ to [submit an issue on GitHub](../../issues).\n\nEveryone is welcome regardless of personal background.
