Technical edge cases & frequently asked questions

Is my input sent to a server?

No. These tools run entirely in browser JavaScript with no external processing.

What are the limits?

Microseconds are truncated to millisecond precision for JavaScript Date. Timestamp magnitudes determine auto-detection.

Are commands executed?

No. Commands and configuration outputs are plain text for you to review and copy.

Can I download the output?

Yes. Copy or download the generated result in the selected format. Large env inputs use a cancellable local worker.
