Frequently Asked Questions

Can Timestamp Validator check against a custom schema?

Timestamp Validator validates syntax and format rules. For schema-level checks, use a dedicated schema validator.

Does Timestamp Validator fix errors automatically?

No. Timestamp Validator reports errors with exact positions but doesn't modify your input. Use it to find problems, then fix them yourself.

Why use a browser tool instead of the command line?

No installation, works on any device, and results are shareable via URL. CLI tools are still better for CI/CD pipelines.
