JSON Utility is a free, browser-based toolkit for developers who work with JSON, YAML, and XML every day.

What it does

  • Validate & beautify JSON, YAML, and XML with clear, line-numbered error messages
  • Convert between JSON, YAML, XML, and JSON Schema
  • Diff two JSON, YAML, or XML files side-by-side
  • Query JSON with JSONPath expressions
  • Validate against a JSON Schema, including a batch mode for checking many files against one schema at once
  • Validate AI tool-calling schemas for OpenAI function calling and Anthropic tool use — checks structure, compiles the schema, and tests sample arguments against it

Why it's different

Everything runs entirely client-side in your browser — no file is ever uploaded to a server, and no account or signup is required. It's built to handle large files smoothly (virtualized editor, so even multi-megabyte JSON pastes stay responsive) rather than freezing like many browser-based tools do.

Who it's for

Backend and frontend developers, API integrators, and anyone building on top of LLM tool-calling APIs who needs a fast, privacy-respecting way to check their data or schemas without leaving the browser.

Koding features and specs

  • Integrated Development Environment (IDE)
    Koding offers an integrated development environment that supports multiple programming languages, which streamlines the development process by providing tools and features in one platform.
  • Cloud-based
    Being a cloud-based platform, Koding allows you to work on your projects from anywhere with an internet connection, fostering better collaboration and convenience.
  • Pre-configured Environments
    Koding provides pre-configured development environments for various technologies, allowing users to bypass lengthy setup processes and start coding immediately.
  • Collaboration Features
    The platform includes collaboration tools such as shared terminals and real-time code collaboration, which are useful for team projects and pair programming.
  • Scalability
    Koding's infrastructure can scale according to the needs of the user, making it suitable for both individual developers and larger development teams.

Possible disadvantages of Koding

  • Pricing
    While Koding offers a free tier, more advanced features and greater resources typically require a paid subscription, which might not be affordable for all users.
  • Performance
    Some users have reported performance issues, especially when working with more resource-intensive projects, as cloud environments can occasionally be slower compared to local machines.
  • Learning Curve
    Although it is feature-rich, the platform can be intimidating for beginners due to its complex interface and extensive toolset.
  • Dependency on Internet
    As a cloud-based platform, Koding requires a stable internet connection for optimal performance, which might be a limitation in areas with poor connectivity.
  • Limited Customization
    Users might find the pre-configured environments limiting if they have specific customization requirements that are not supported out of the box.

JSON Utility features and specs

  • AI Tool-Calling Schema Validator
    Validate OpenAI function-calling and Anthropic tool-use schemas — checks structure, compiles the schema, and tests sample arguments against it.
  • Format Conversion
    Convert data between JSON, YAML, XML, and JSON Schema in one click.
  • JSON, YAML & XML Validation
    Validate and beautify JSON, YAML, and XML with clear, line-numbered error messages.
  • JSONPath Queries
    Run JSONPath expressions against JSON data to extract or filter values.
  • JSON Schema Validation
    Validate JSON documents against a JSON Schema, including a batch mode for checking many files against one schema at once
  • Batch JSON Validation
    Validate many JSON files against one schema at once — drag in a folder of files and instantly see which pass, which fail, and why.
  • 100% Client-Side / No Upload
    Every tool runs entirely in your browser — no file is ever sent to a server, no account required.

Questions & Answers

As answered by people managing Koding and JSON Utility.

What makes your product unique?

JSON Utility's answer:

  • Runs entirely in the browser — no file is ever uploaded to a server
  • No account or signup required, unlike many competing JSON tools
  • Includes a batch schema validator for checking many files against one schema at once
  • Includes a dedicated AI tool-calling schema validator for OpenAI function calling and Anthropic tool use — a feature few if any JSON tools offer

Why should a person choose your product over its competitors?

JSON Utility's answer:

  • Free, with no signup and no data ever leaving your browser
  • Covers more ground than most single-purpose JSON tools: validation, conversion, diffing, JSONPath queries, JSON Schema validation, and AI tool-calling schema validation — all in one place
  • Built to stay responsive even on large, multi-megabyte files, where many browser-based tools freeze or crash

How would you describe the primary audience of your product?

JSON Utility's answer:

  • Backend and frontend developers working with JSON, YAML, and XML data day-to-day
  • API integrators and QA engineers who need to validate or diff data quickly
  • Developers building on LLM tool-calling APIs (OpenAI function calling, Anthropic tool use) who need to validate their schemas before deploying

What's the story behind your product?

JSON Utility's answer:

It started as a simple JSON validator/formatter and grew into a full toolkit as more everyday developer needs came up — conversion between formats, diffing, JSONPath querying, and schema validation.

The AI tool-calling schema validator was added as more developers began building agents and needed a fast, offline way to sanity-check tool definitions before wiring them into a live model.

Which are the primary technologies used for building your product?

JSON Utility's answer:

  • React, Vite, and React Router on the frontend
  • Ajv for JSON Schema compilation and validation
  • Fully static, server-side prerendered HTML per route, deployed on Vercel — no backend server, since every tool runs client-side

Who are some of the biggest customers of your product?

JSON Utility's answer:

JSON Utility is a free, anonymous tool with no signup — we don't track or identify specific customer organizations. It's used by individual developers and small teams across the industry.
