Frequently Asked Questions
Answers to common questions across all JSON Tool Suite tools.
General
What is JSON Tool Suite?
A lightweight set of browser-based tools to format, validate, and compare JSON quickly.
Do I need to sign up?
No. All tools work instantly without accounts or logins.
Is my data private?
Yes. Everything runs locally in your browser and nothing is uploaded.
Which tools are included?
Formatter, Validator, Compare, and JSON Converter are available in this suite.
Does it work on mobile?
Yes, the layout is responsive and works on modern mobile browsers.
Can I use large JSON files?
Yes, the tools are optimized for large payloads, but very large files may be slower.
Is JSON Schema supported?
Yes, the validator can use JSON Schema when provided.
Does the compare tool ignore key order?
You can compare deeply, but key order is preserved as parsed by the browser.
Can I share results?
Use the copy buttons or minify output before sharing.
Is it free to use?
Yes. The suite is free and runs entirely in the browser.
JSON Formatter
What does the formatter do?
It beautifies JSON with consistent indentation and spacing.
How do I minify JSON?
Click Minify to remove whitespace and shrink the JSON output.
Can I change indentation size?
Yes, adjust the indent control to 2, 4, or custom spaces.
Why is the output empty?
The input might be invalid JSON. Check the error message for details.
Does the formatter reorder keys?
It keeps the order as parsed by the browser, which usually matches your input.
Can I copy the formatted output?
Yes, use the Copy button to copy the output text.
What is Tree View?
A collapsible view that lets you explore JSON structure.
Why does Tree View not show?
Make sure the checkbox is enabled and the JSON is valid.
Can I format arrays only?
Yes, any valid JSON value is supported, including arrays.
Does it fix invalid JSON?
It can attempt a best-effort auto-fix, but you should verify the result.
JSON Validator
What does the validator check?
It checks JSON syntax and can validate against a schema.
How do I validate JSON?
Paste JSON into the input and click Validate.
What is JSON Schema?
A structured format that defines the expected shape of JSON data.
Can I validate without a schema?
Yes, syntax validation works without a schema.
Why do I see an error line/column?
The validator locates the first parsing error for quicker fixes.
Does it validate arrays?
Yes, any valid JSON value can be validated.
What if the schema is invalid?
You will see an error indicating the schema problem.
Is my data private?
Yes, all validation runs locally in your browser.
Can I copy the validation result?
Yes, you can copy output or error messages.
Does it change my JSON?
No, validation does not modify your input.
JSON Compare
What does JSON Compare do?
It highlights differences between two JSON inputs side by side.
What kinds of changes are shown?
Added, removed, and modified values are marked clearly.
Does it compare nested objects?
Yes, deep comparison is supported for nested structures.
Can I ignore key order?
The compare is based on parsed objects; key order is not treated as a difference.
Why are there no results?
Make sure both inputs are valid JSON before comparing.
Does it handle large JSON?
Yes, but very large files may take longer to render.
Are arrays compared by index?
Yes, array elements are compared by position.
Can I copy the diff output?
You can copy the highlighted text from the output panels.
Is my data sent anywhere?
No, comparisons run locally in your browser.
What if inputs are identical?
The tool will report no differences found.
JSON Converter
What formats can I convert to?
XML, CSV, HTML, Word, and PDF are supported.
Does conversion happen in the browser?
Yes. All conversions run locally without uploads.
How do I export a PDF?
Use Export to open a print view and save as PDF from your browser.
How do I export a Word document?
Use Export to download a .doc file created from HTML.
What JSON shapes work best for CSV?
Arrays of objects are ideal. Keys become column headers.
Can I convert a single object to CSV?
Yes. It will create a single-row CSV.
Why is the output blank?
Invalid JSON or unsupported structures can prevent conversion.
Does the converter preserve key order?
It uses the key order parsed by the browser.
Can I copy the converted output?
Yes. Use the Copy Output button.
Is there a file size limit?
No hard limit, but very large files may take longer to convert.
