About JSON Tools

Format, validate, compare and convert JSON without ever leaving your browser

JSON is the language of modern APIs, configuration files and data interchange. Almost every web service you call, every config file you edit, every modern database export — they all speak JSON. And almost every developer, at some point in a day, needs to pretty-print a minified blob, validate that a payload is well-formed, diff two responses, or convert JSON to CSV for a spreadsheet.

ToolsRift offers 25+ JSON tools covering every part of that daily workflow: a fast formatter and minifier, a strict validator with error line numbers, a deep diff with side-by-side comparison, JSON ↔ CSV, JSON ↔ YAML, JSON ↔ XML converters, JSONPath tester, JSON Schema validator, JSON to TypeScript types and JSON to Go struct generators, and tools to escape JSON for embedding in strings.

Everything runs entirely in your browser. You can paste API responses containing customer data, internal IDs or auth tokens with full confidence that nothing leaves your machine.

Why ToolsRift

Why our json tools are different

Almost every JSON formatter on the open web sends your input to a server. That is a real problem when the input is a production API response, a database export, or anything containing PII. ToolsRift parses, formats, validates and converts JSON entirely on the client side using native JavaScript and battle-tested libraries — there is no upload, no logging, and no third-party analytics that would see your data.

Beyond privacy, our tools are also faster. There is no network round-trip, so a 5 MB JSON file pretty-prints in the same second you paste it. The validator points to the exact line and column of any syntax error, with a short explanation — not just a generic "invalid JSON".

How It Works

How to use json tools

1
Pick the JSON tool you need
Open the JSON dashboard and pick formatter, validator, minifier, diff, converter or one of the specialized tools.
2
Paste your JSON
Drop your JSON into the input box. The formatter accepts both already-formatted and minified input. Validators show errors live as you type.
3
Adjust indentation or options
Choose 2-space, 4-space or tab indentation. Toggle sorted keys to make diffs easier. For converters, pick the output format and delimiter (CSV) or root element (XML).
4
Copy or download the output
One click copies to clipboard. For larger outputs, download as .json, .csv, .yaml or .xml. The input stays in place so you can iterate quickly.

FAQ

Frequently Asked Questions

Answers to common questions about our json tools.

What's the maximum JSON size I can format?+
Tools handle multi-megabyte JSON without issue. Browser memory is the only real limit — modern laptops can comfortably format 100+ MB. For extremely large files, the formatter automatically uses streaming mode to avoid freezing the page.
Why does my JSON show a validation error when it looks fine?+
JSON is stricter than JavaScript object literals. Common pitfalls: keys must be in double quotes (not single quotes), no trailing commas, and no comments. The validator points to the exact line so you can spot it quickly.
Can I convert nested JSON to CSV?+
Yes. The JSON to CSV converter flattens nested objects using dot notation (user.address.city) and offers options for handling arrays (join with comma, expand to multiple rows, or stringify). For deeply nested or mixed structures, it picks sensible defaults you can override.
Is the JSON diff aware of array order?+
Both modes are available. The default mode is order-sensitive (matches what most APIs care about). Toggle "Ignore array order" to compare sets where order does not matter — useful for tag lists, permission arrays, etc.
Does the JSONPath tester support all operators?+
It supports the full JSONPath spec including filter expressions ($..book[?(@.price < 10)]), wildcards, recursive descent and array slicing. Results are highlighted in the source document.
