About this tool
Parse date and timestamp strings in a YAML file and convert them between formats and timezones. Handles ISO 8601, US/EU dates, Unix epoch, and custom patterns. All processing stays in your browser.
Frequently Asked Questions
What date formats does the YAML date parser support?
Auto-detection handles ISO 8601 and standard text dates. You can also parse Unix epoch (seconds or milliseconds), US dates (MM/DD/YYYY), EU dates (DD/MM/YYYY), or any custom pattern using strptime syntax.
Can I convert between timezones in a YAML file?
Yes. Select the source timezone your dates are stored in and the target timezone you want to convert to. The tool uses AT TIME ZONE for accurate conversion.
What happens if a date cannot be parsed in a YAML file?
TRY_CAST is used for safe parsing — unparseable values become null rather than causing an error. Check the result preview for any nulls before downloading.
Is my data private?
Yes — completely. Your file is never uploaded to any server. Everything runs locally in your browser using WebAssembly — processing happens entirely inside your tab. Once you close the tab, nothing is retained.
What is the maximum file size?
The free limit is 50 MB. For larger files, performance depends on your device's available memory — most modern machines handle 500 MB to 1 GB comfortably.
