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).

Note: If the console gets in your way, hold down Shift and then move your mouse over it it will move to the opposite side of the page. The results box will immediately reflect your changes. If desired, edit the XPath query directly in the console.The query box will continuously update to show the XPath query for the element below the mouse pointer, and the results box will show the results for the current query. Hold down Shift as you mouse over elements on the page.Hit Ctrl-Shift-X ( or Command-Shift-X on OS X), or click the XPath Helper button in the toolbar, to open the XPath Helper console.Open a new tab and navigate to any webpage.Now the icon for XPath Helper will appear on the top right-most side of the Chrome browser.IMPORTANT: After installing this extension, you must reload any existing tabs or restart Chrome for the extension to work. ![]() Once it is installed, it will display a pop-up message for Succesful installation.Note: If you open the URL in any other browser, you will see the option 'Available in Chrome' instead of 'Add to Chrome' ![]() How to Install XPath Helper Plugin for Chrome Browser?
