Change JSON Syntax lets you convert JSON into different syntactic styles: standard, single-quoted, or JavaScript object literals all instantly in-browser.
How to Use:
Paste your JSON into the input box or import a file using “Choose File.” Then pick how you want it transformed. You can keep it as normal JSON, flip quotes to single quotes, or remove the quotes from keys to match JavaScript object literal style. The output updates live as soon as you choose a mode. Below the output, you’ll see a running character count. When you’re happy with the result, copy it, export it, or clear everything and start over.
What Change JSON Syntax can do:
Change JSON Syntax lets you take valid JSON and reformat it depending on what you need. Maybe you’re pasting into JavaScript code and want object literal syntax. Maybe your backend prefers single quotes. This tool helps you jump between formats fast without editing by hand. It doesn’t try to validate or correct it assumes you gave it valid JSON and just changes how it looks. File import makes it easy to load in large blobs of data, and the output counter helps keep track of changes as you tweak modes.
Example:
Input:
{ "name": "Alice", "age": 30 }Single-Quoted JSON:
{ 'name': 'Alice', 'age': 30 }JavaScript Object Literal:
{ name: 'Alice', age: 30 }Common Use Cases:
Sometimes you don’t want to retype everything just to switch styles. Change JSON Syntax is great for turning API responses into code-ready objects, matching formatting for template engines, or prepping demo data. It keeps your workflow moving without ever needing an extension or formatter plugin.
Useful Tools & Suggestions:
To tweak formatting styles, Use Single Quotes in JSON can be applied first if double quotes aren’t your thing. Then, once the syntax feels right, Prettify JSON helps smooth out the layout so everything’s easier to read.
