About ByteJSON

Browser-based developer tools, tutorials, and educational calculators.

Our Mission

ByteJSON helps developers and technical users solve everyday data, API, encoding, and debugging tasks without installing a package or sending private input to a remote service. Most tools run entirely in the browser, so pasted JSON, tokens, config files, and examples stay on your device during normal use.

The site also includes long-form tutorials and educational calculators. Those pages are written to explain the reasoning behind a result, not only to provide a quick output.

How ByteJSON Is Maintained

ByteJSON is maintained by an independent developer, not by an anonymous publishing network. New pages are reviewed for practical usefulness, internal links, privacy behavior, and whether the page adds something more useful than a thin template.

Developer tutorials use runnable commands, code examples, or reproducible debugging steps where possible.
Tool pages are designed around real workflows: validation, conversion, inspection, generation, and repair.
Finance pages are educational calculators and are not a substitute for professional tax or financial advice.
Corrections can be sent by email or through the public GitHub profile linked below.

What We Build

JSON ToolsFormat, validate, repair, compare, and inspect JSON.Encode and DecodeWork with Base64, URL encoding, HMAC, PEM, and related formats.Backend ToolsUse practical helpers for Docker, JWT, regex, hashes, UUIDs, and semver.Data ToolsValidate YAML, TOML, XML schemas, CSV, JSONL, and environment files.API ToolsInspect Google Services JSON, MIME types, user agents, GraphQL, and API keys.Image ToolsConvert and inspect image formats directly in the browser.

Tutorials and Review Standards

ByteJSON tutorials are written for readers who need to fix or understand a real technical problem. A useful tutorial should include context, working examples, common mistakes, and links to related tools or follow-up reading.

Transparency and Privacy

You can find the public GitHub profile for the project maintainer at github.com/colodoo. Bug reports, source-related questions, and correction requests are welcome.

ByteJSON does not require an account for normal use. Tool input is processed in the browser whenever the tool can reasonably work that way. Basic analytics may be used to understand aggregate site performance, but pasted tool input is not stored as part of that measurement.

Who Builds This

ByteJSON is built and maintained by Zhisan, an independent developer focused on browser-based utilities, API workflows, and practical data transformation tools.
