Every developer keeps a "format JSON online" tab pinned somewhere. It is one of the most-Googled queries on the internet, and the unfortunate state of the art is that most of those tools serve ads, throttle paste size, or quietly inspect your payloads. The Format Tools hub on Ai2Done is built for the opposite: every formatter runs entirely in your browser via WebAssembly, so you can safely paste an authentication response, a database export or any other sensitive payload without leaking it.
The hub anchors around four flagship formatters. Format JSON handles pretty-printing, minification, tree-view collapse / expand, syntax-error highlighting and JSONPath search; it comfortably handles multi-megabyte payloads that crash competitor sites. Format XML covers indentation, namespace-aware formatting and XPath evaluation. Format SQL normalises whitespace and keyword casing across MySQL / PostgreSQL / Oracle / SQL Server dialects. Format YAML reflows for canonical indentation and surfaces parse errors with line numbers.
Each formatter ships as a TinyGo-compiled Wasm binary (typically 100–300 KB after Brotli), which means the tools load fast and stay responsive even on older laptops. The first paste triggers Wasm initialisation; subsequent operations are instantaneous. Output can be copied, downloaded, or sent to other tools in the hub for further processing.
Heavy users include backend engineers debugging API responses, data analysts reshaping exports, ops engineers reading container logs, and anyone who needs to read a minified config file at 2am. Because the engine never sees a server, you can use these tools on production credentials, API tokens or PII without exposure — a meaningful improvement over the major competitors who explicitly disclose that pasted content may be logged.
Pair the hub with the Dev Tools hub for broader engineering utilities (the two overlap deliberately) and with the JSON Tools / CSS Tools hubs when you need a single-format focused workflow. If you have an internal style guide, the formatter defaults are designed to be a reasonable starting point; copy the output into your editor and run your project's formatter to lock in house style.
