Developer & Data Tools — Frequently Asked Questions
Is my code or data stored anywhere?
For these developer utilities, processing runs locally in your browser and we don't upload your pasted code or data to our servers for that processing.
Can I format large files?
Yes. Most formatters handle files up to several megabytes without issues. Very large files may be slower on older devices.
Are the formatters configurable?
Most formatters use standard conventions (2-space indent for JSON, etc.). Custom configuration is planned for future updates.
