About JSON Studio
Lightweight utilities for everyday development
JSON Studio is an online toolkit for developers, students, and technical teams. It brings common formatting, conversion, validation, and comparison tasks into one interface that can be used without an account.
What we provide
The site includes tools for JSON, SQL, XML, YAML, encoding, hashes, timestamps, regular expressions, and text comparison, alongside curated learning resources. Each tool's page and actual output are the authoritative description of its behavior.
How we design
We prioritize clear, fast, and reviewable workflows. Tools should surface their input, output, and errors so you can inspect results before copying, downloading, or using them in code.
- Core tools available without an account
- Text and structured-data processing performed in the browser where possible
- Chinese and English interfaces with directly accessible locale routes
- Ongoing fixes for links, copy, and compatibility
Data and privacy
Normal tool processing runs in the browser. JSON Studio does not intentionally send content pasted into a tool editor to its own servers as part of a tool's function. Analytics and advertising services may process device, browser, or visit-event information; see the Privacy Policy for details.
Continuous improvement
We improve formatting behavior, error messages, accessibility, and content from feedback. If you find an incorrect conversion, a broken page, or have a tool request, send reproducible steps and a redacted example through the contact page.
Frequently asked questions
Do I need an account to use JSON Studio?
No account is currently required for the core tools.
Can I use a tool's output in production?
Validate the output, field meanings, SQL dialect, and target-system compatibility first. These utilities do not replace code or security review.
How can I report an issue or suggest a feature?
Use the contact page and include the page URL, steps to reproduce, and a minimal example with secrets removed.
