{ “title”: “Cron Generator — Build Cron Expressions Visually”, “description”: “Build a cron expression with live preview of the next 5 firing times. Each field validates independently.

The interface loads from your device — nothing is fetched from a server.” }, { “title”: “Read the byte-level inputs”, “body”: “Each control is wired to a JavaScript handler that processes input locally. Drop a file or paste a value and the work runs immediately.” }, { “title”: “Download the result”, “body”: “When the result is ready, click Download or Copy to grab it. The output stays on your device; close the tab and it is gone.” } ], “faq”: [ { “q”: “How does the Cron Generator work in my browser?”, “a”: “All the processing for /tools/cron-generator is implemented in JavaScript and WebAssembly. We open the file or input locally with the FileReader API or a paste, process it in JavaScript on the same page, and produce the result without ever uploading the file to a server. The work happens on your device, not ours.” }, { “q”: “Is the input file uploaded to any server?”, “a”: “No. Every tool on ToolConvoy processes files strictly in your browser. Network requests never carry your input. You can verify this by opening the Network tab of your browser’s developer tools while using the tool — you will see only the initial page load.” }, { “q”: “What happens to my file after I close the tab?”, “a”: “All data lives in browser memory while the tab is open. Closing the tab releases that memory. There is no server-side storage, no analytics database, no logging of file contents.” }, { “q”: “Does this tool work offline?”, “a”: “Once the page loads, all processing continues to work offline. Subsequent page navigations may require a network connection if you move to a different route.” } ], “limitations”: [ { “label”: “Browser memory limits”, “detail”: “For very large inputs (hundreds of MB), the browser tab may run out of memory.
