JSON, Base64, CSV, SQL, and URL utilities for formatting and data conversion — free, no signup.
Developers still need everyday utilities that work when a corporate laptop blocks package installs: pretty-print a messy API payload, encode a URL fragment, flip CSV to JSON for a fixture file, or tidy a SQL dump before a code review. The Developer Tools category on Big File Sharing is a set of browser utilities for inspection, transformation, and validation—without storing your payloads as permanent “snippets” in a social pastebin.
Use the JSON Formatter when minified gateway responses are unreadable or invalid commas break parsers. CSV to JSON and JSON to CSV help seed mock databases and reverse analytics exports. Base64 and URL encode/decode show up in auth headers, data URIs, and debugging weird query strings. The SQL Formatter makes review of multi-join reports humane on locked-down jump hosts.
These pages are optimized for small-to-medium payloads and one-off tasks. Extremely large dumps may hit practical request sizes; prefer local formatters or CI for multi-hundred-megabyte nightly extracts. Never paste production secrets into any third-party tool if policy forbids external processing—run offline instead. Where you do process non-secret fixtures here, short retention and no public listing reduce residual risk compared with shared cloud notebooks that surface history next to ads.
How this fits a toolchain: pair browser tools with your editor for first-pass validation, then commit clean fixtures to git. Use related utility links when a data path needs both steps (CSV to JSON, then format). For shipping large build artifacts or log bundles to a teammate, use private temporary transfer on the homepage rather than attaching dumps to chat forever.
Browse the six developer tools below. Each page notes expected input shape, common error modes (malformed JSON, multi-byte URL quirks), and when a CLI remains the better tool for scripted automation.
