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. 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). Option 1 (recommended) – Install it from the Chrome Web Store. Some JSON documents for testing it on: Installation
