Terms of Use

These terms apply when you use Jsonformatter (jsonformatter.tech). By using the site, you agree to them. If you do not agree, please do not use the site.

The service

Jsonformatter is operated by Luis Carvalho, an individual, under the Carvalho Software brand.

Jsonformatter offers free online tools to format, validate, convert, compare, encode and decode text, covering JSON, YAML, XML, CSV, HTML and CSS, plus Base64, URL and JWT. You can use them without creating an account.

Acceptable use

Use the site only in a lawful and responsible way. You agree not to:

  • use the site for anything unlawful, or to harm or harass other people;
  • try to gain unauthorized access to the site, its servers or any other system;
  • overload the site, or use scripts, bots or other automation to put heavy or repeated load on it;
  • paste data that you are not allowed to process, or secrets such as passwords, access tokens or keys.

For the details, see the Content Policy

Your text and your responsibility

You are responsible for the text you process with the tools and for having the right to use it.

To learn how the site handles information, see the Privacy Policy

Accuracy of results

The tools follow the rules of each format, but a result can still contain errors, and a conversion between formats can change how your data is represented. Check every result before you rely on it, and keep a copy of your original data.

Spreadsheet programs can interpret what is in a CSV file: text that looks like a formula may be treated as one, and values may be retyped, for example as numbers or dates. When you open a CSV file in a spreadsheet, import it as text. The site cannot promise that a CSV file is safe in every spreadsheet program.

No warranty

The site and its tools are provided “as is” and “as available”, with no warranty of any kind, express or implied. This includes any warranty of merchantability, fitness for a particular purpose, accuracy or non-infringement, and any promise that the site will be available without interruption, free of errors or secure. Where the law does not allow some of these exclusions, they apply only as far as the law allows.

Limitation of liability

To the extent the law allows, Jsonformatter and its operator are not liable for any indirect, incidental, special or consequential damages, or for any loss of data, profits or business, arising from your use of the site, its tools or their results, or from not being able to use them, even if we were told that such damage could happen.

Nothing in these terms limits a liability that the law does not allow to be limited, or any right you have as a consumer under mandatory law.

Third-party ads and links

The site shows ads served by Google AdSense, and it may link to other websites. Ads and linked sites belong to third parties, who have their own terms and privacy policies. We do not control or endorse them, and we are not responsible for their content, products or practices. If you click an ad or a link, you leave Jsonformatter and the terms of that third party apply.

To learn how ads work and what choices you have, see the Privacy Policy

Governing law

These terms are governed by the laws of Brazil, where the site is operated. This does not remove any right that the mandatory consumer protection law of the place where you live gives you.

Changes to the site and to these terms

We may change, suspend or stop the site or any of its tools at any time, and we may update these terms as the site changes. The version on this page is the current one. If you keep using the site after a change, you accept the updated terms.

Contact

If you have a question about these terms, write to us by email. Do not include secrets or text that you pasted into a tool. We do not promise a response time.

  • JSON Formatter

    Format JSON with one consistent layout: even indentation, one value per line, your values untouched. Runs the same formatter as JSON Beautifier.

  • JSON Validator

    Check whether your text is valid JSON. If it is not, see the first problem with its line and column, highlighted in your text.

  • JSON Diff

    Compare two JSON documents by structure, ignoring key order, and see every added, removed and changed path in one list.

  • JSON Schema Validator

    Validate JSON against a JSON Schema (draft 2020-12, or draft-07 through $schema) and see each error with the path where it occurs.

  • JSON Schema Generator

    Generate a JSON Schema (draft 2020-12) from a sample JSON document, ready to copy and refine.

  • JSON Beautifier

    Beautify minified or unevenly spaced JSON into readable, indented text, with your values untouched. Runs the same formatter as JSON Formatter.

Convert JSON

  • JSON to CSV

    Convert a JSON list of objects, or the first list of objects inside an object, to plain CSV text.

  • CSV to JSON

    Convert CSV to a JSON array of objects, using the header row as keys. Comma, semicolon and tab separators are detected, and values stay as text.

  • JSON to XML

    Convert JSON to plain, readable XML, with your numbers and text copied exactly as written.

  • XML to JSON

    Convert XML to JSON, with attributes as @name keys and repeated elements gathered into arrays so the structure carries over.

  • JSON to YAML

    Convert JSON to readable block YAML with 2 or 4 spaces of indentation, keeping every value and every number exactly as you wrote it.

  • YAML to JSON

    Convert YAML to JSON with anchors and aliases resolved. A file with several documents becomes a JSON array.

YAML

  • YAML Validator

    Check whether your YAML is valid under the YAML 1.2 Core rules, in one or several documents, and see the line and column of the first problem.

  • YAML Viewer

  • YAML Formatter

    Format YAML with consistent indentation while keeping comments and values.

HTML, XML and CSS

  • HTML Formatter

    Format HTML into readable, indented markup. The result is plain text: scripts do not run and nothing in your HTML is loaded.

  • XML Formatter

    Format XML with clear indentation while preserving its content and meaning.

  • CSS Beautifier

    Beautify minified CSS into readable rules, one declaration per line, without changing what the CSS does. Runs the same formatter as CSS Formatter.

  • CSS Formatter

    Format CSS you maintain with one consistent style: the same indentation, spacing and spelling everywhere. Runs the same formatter as CSS Beautifier.

Encode & Decode

  • Base64 Encode/Decode

    Encode text to Base64 or decode Base64 back to text as UTF-8, with an option for the URL-safe Base64URL alphabet.

  • URL Encode/Decode

    Encode or decode text with %XX sequences, either as a URL component or as a full URL whose separators stay intact.

  • JWT Decoder

    Decode a JWT in your browser to read its header and payload, see the exp, iat and nbf dates and whether it has expired. The signature is not verified.
