![]() In future JSON Formatter might switch from using JSON.parse to a custom parser (if performance allows) in order to detect when a value has been 'changed' by parsing and show an appropriate warning. The "Parsed" buttons represents what you'll get from JSON.parse. But I just want to see exactly what the server spits outįor now, your best option is to just use the "Raw" button to see the raw JSON. This V8 implementation detail has since become standardised. Historically, the JavaScript standard explicitly stated that object keys can be iterated in any order, and V8 took advantage of this by moving numeric string keys (like "1" or "99999") to the top to facilitate a small performance optimisation. Chrome extension that auto-formats JSON when you view it in a browser tab. It's the same order you'll get with Object.keys( JSON.parse(json) ) in JavaScript. What you see in JSON Formatter is a representation of the parsed object/array. Why are object keys sometimes in the wrong order? If your API endpoint really needs to represent numbers outside JavaScript's safe range, it should quote them as strings. JSON Formatter shows you the parsed values, exactly the same as what you'll see after loading the JSON in JavaScript. It's not JSON Formatter doing this, it's the native JSON.parse in V8. Extremely precise floating point numbers are rounded to 16 digits.Anything below Number.MIN_SAFE_INTEGER ( -2^53 + 1 or -9007199254740991) is adjusted up to that number.Anything above Number.MAX_SAFE_INTEGER ( 2^53 - 1 or 9007199254740991) is adjusted down to that number.This is a limitation of JavaScript and therefore a limitation of JSON as interpreted by your web browser. Select the dist folder you built above.įAQ Why are large numbers not displayed accurately?.Open Chrome and go to chrome://extensions.To build and rebuild whenever files change: Optional: if using VSCode and you need to mess with the Deno build scripts, install the official Deno plugin and set "deno.enablePaths".Run pnpm i to get TypeScript typings for chrome (or use npm i if you prefer).Option 2 – Install it from source (see below). ![]() With this plugin installed, simply select any JSON text and click the JSON Formatter icon. Option 1 (recommended) – Install it from the Chrome Web Store. A fast and easy way to format and explore JSON content. The original JSON Formatter, now with optional dark mode Auto-formats JSON when you load it in a browser tab. Download JSON, once it's created or modified. parseJSON and JSON.stringify to beautify JSON easy for a human to read and analyze. Use Auto switch to turn auto update on or off for beautification.
