Developer Tools
Everyday developer utilities for formatting and validating JSON and XML, encoding and decoding Base64 and URLs, generating UUIDs and hashes, and converting timestamps — built for speed with zero setup.
About Developer Tools
Most developer tasks don't need a full IDE or a package install — they need a quick, reliable utility that does one thing correctly. Formatting a minified API response, checking whether a config file is valid JSON, generating a UUID for a test fixture, or converting a Unix timestamp to a readable date are all things that come up constantly during day-to-day development work, and FilesFortress's developer tools are built to handle exactly that.
The JSON tools cover the full lifecycle of working with JSON data: the Formatter turns minified or poorly indented JSON into a readable, properly indented structure; the Validator checks syntax and points out exactly what's wrong when something doesn't parse; and the Minifier strips whitespace back out once you're ready to ship. The same three-tool pattern is available for XML, covering configuration files and legacy API formats that still rely on it.
Base64 and URL encoding are handled as dedicated encode/decode pairs, since the two use different character sets and serve different purposes — Base64 for embedding binary data inside text formats like JSON or HTML, and URL encoding for making arbitrary text safe to include inside a URL. Both are one-way lookups with no ambiguity about what the tool does, which keeps them fast to use mid-task.
Rounding out the category, the UUID Generator produces random v4 identifiers for test data or database keys, the Hash Generator produces SHA-1, SHA-256, SHA-384, and SHA-512 hashes using the browser's built-in Web Crypto API, and the Timestamp Converter moves between Unix timestamps and human-readable dates in both directions. None of these tools require an account, an API key, or a network request — everything runs locally the moment you load the page.
