How to use Use Single Quotes in JSON
- 1. Paste your JSON. Put standard double-quoted JSON into the input pane. There are no settings to adjust; the conversion happens automatically as soon as the document is recognized as valid JSON.
- 2. Let it convert every quote. Every double quote around a key or string value gets replaced with a single quote, producing a JavaScript-object-literal style of output rather than strict JSON.
- 3. Copy the single-quoted version. Copy the result and paste it into a JavaScript file or wherever a single-quote style is expected, keeping in mind the output is no longer valid JSON on its own.
When to use Use Single Quotes in JSON
Use Single Quotes in JSON converts every double-quoted key and value in a JSON document into single quotes. It is for the moment JSON data needs to be hardcoded into JavaScript source and match a project's single-quote style rather than staying strict JSON.
- Matching an ESLint quotes rule. A codebase's ESLint config enforces single quotes for string literals, and you want to paste a JSON sample as a JavaScript object without triggering the linter on every quote.
- Embedding data as a JS object literal. You are hardcoding a small piece of JSON-shaped data directly into a .js file and want it to match the surrounding code's single-quote convention instead of standing out.
- Writing a Python-style dictionary. You need a JSON sample to look like a Python dict literal for a script or notebook, and Python's convention leans toward single quotes for strings.
- Matching a project's existing style guide. A team's internal style guide calls for single quotes everywhere, and you have a JSON snippet from an external API that needs to be reformatted before it fits in.

Use Single Quotes in JSON runs as plain JavaScript in your browser tab, with no server behind it. Make all keys and values in a JSON single-quoted. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's JSON Tools section, 90 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
There is nothing to configure. Provide the input and the result appears on its own. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
Frequently asked questions
Does Use Single Quotes in JSON cost anything?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
No data leaves your device. The whole tool is JavaScript that runs inside your browser tab, so there is no upload, no server-side processing and no log of what you did. If you disconnect from the internet after the page loads, it keeps working.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
Nothing to install and no account needed. Open the page in any up-to-date browser, including on a phone or tablet, and the tool is ready.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
