AT USE developer tools: server-side processing and 20 MB file support

#devtools #webdev #tools #json

Six developer tools at AT USE process input on the server — not in your browser. That means large files work.

Server-side tools (file limits)

Tool	Limit
YAML to JSON	1 MB
CSS Formatter/Validator	500 KB
CSV to JSON	20 MB
JSON to CSV	20 MB
JSON Schema Validator	20 MB
HTML Formatter	20 MB

Files run through our server infrastructure. Browser-only tools cap at your device's available RAM and can't handle server-side operations (API calls, file parsing at scale).

Browser-side tools (privacy angle)

The other 9 developer tools — hash generator, JSON formatter, base64 encoder/decoder, URL encoder/decoder, regex tester, UUID generator, cron builder, number base converter, XML formatter — run entirely in your browser.

Nothing leaves your device. No upload, no server processing, no logs.

All 15 tools now answer "Does this work on large files?"

Every developer tool page now has a direct FAQ answer on this in its structured data (FAQPage JSON-LD). You'll see it in Google rich results and AI-generated answers soon.
