Cron Parser
Explain a cron expression in plain English, list the next run times in your local time zone, and edit fields or presets. Paste a 5- or 6-field crontab line. Parsing is local, so job schedules never hit a cron API.
Runs in your browser. Nothing is uploaded.
About this tool
Explain a cron expression in plain English and list the next run times in your resolved time zone. 5-field crontab lines and 6-field expressions with seconds are both accepted. Next runs use the local IANA zone from the browser.
How to use: paste 0 9 * * 1-5, pick a preset, or edit the five field boxes. Read the description, then copy any upcoming ISO timestamp. Invalid syntax shows a parser error instead of a guessed schedule.
Example: 0 9 * * 1-5 is At 09:00, Monday through Friday, with the next weekday 09:00 slots listed below. Quartz-only year fields are out of scope.
Schedules are not sent to a cron host. Related: timestamp converter if you needed to inspect one of those ISO times. After load, explaining works offline.
FAQ
Related Convert tools
JSON ↔ YAML
Convert JSON to YAML and YAML back to JSON in the browser. Paste a config, Kubernetes snippet, or API fixture and copy the other format. Parsing uses js-yaml locally. Documents are never posted to a converter.
JSON ↔ TOML
Convert JSON objects to TOML and TOML documents back to JSON in the browser. Handy for Cargo.toml, pyproject, and app config fragments. Parsing stays on-device.
JSON ↔ XML
Convert JSON objects to XML and XML documents back to JSON. Useful for SOAP leftovers, RSS, and mixed API stacks. XML is parsed with the browser DOMParser so payloads stay on the device.
JSON ↔ CSV
Turn an array of JSON objects into CSV, or parse CSV headers into JSON objects. Quote-aware parsing runs in the tab so spreadsheets of IDs and emails are not uploaded to a conversion service.
JSON to SQL
Turn a JSON object or array of objects into SQL INSERT statements. Set a table name, copy the query, and keep rows on the device instead of pasting fixtures into a hosted converter.
CSV ↔ TSV
Convert comma-separated values to tab-separated values and back, preserving quoted fields. A small delimiter swap for dumps you would rather not paste into a spreadsheet SaaS.
