The Crontab Migration Tool processes cron-related input data and produces structured, formatted output ready for use in documentation, configuration files, or deployment scripts. All processing runs entirely in your browser with no data transmitted to any external server.
The tool validates cron expressions before processing and provides clear error messages for invalid input. The output can be copied to clipboard or downloaded as a JSON file for further use.
For accessibility, all interactive elements use native HTML controls with visible labels. Error messages use the alert role for screen reader announcement. The responsive layout collapses to single-column on narrow screens.
The implementation follows the supplied reference architecture: config, EJS template and module file, with scoped sct-* CSS, browser-local processing, validation before processing, sample and clear controls, and exports generated from the same result data used on screen.
Input is treated as untrusted data and dynamic values are escaped before being rendered. The tool does not execute any commands or evaluate user input as code. Generated configuration such as shell scripts or YAML should still be reviewed before deployment.
Export data is derived directly from the current result object, avoiding a separate interpretation layer. That means copy, JSON and text output stay aligned with what the interface calculated or generated.
The tool uses conservative parsing: malformed input is rejected rather than producing misleading partial results. This means you can safely paste raw data and get only valid output.
No framework, external API, CDN or package is required for the implemented functionality. The page uses labeled controls and accessible alert/status regions, keyboard-focusable native buttons, responsive grids, and bounded scroll areas.
