From Excel XLSX to YAML in four moves
Load the Excel XLSX workbook (file tab only) and pick the active sheet.
Confirm header row and that typed columns (dates, IDs) look right in the grid.
Use mapping or options on this page so each Excel XLSX field lands in the correct YAML shape.
Emit YAML for repos, Helm samples, or CI matrices—lint before apply.
Before you convert
- Merged cells and hidden rows may not map 1:1 to flat output.
- YAML output should be treated as a snapshot until the next source refresh.
- Keep a copy of the original Excel XLSX as the audit trail after you ship YAML.
Choose the right output
When YAML is the right output
- You are promoting Excel XLSX into YAML because the next hop names that format in its contract or runbook.
- Downstream asked explicitly for YAML while editors still live in Excel XLSX.
- You need a deterministic export for CI, legal, or partner review—not a live sync.
- The receiving system has a documented YAML ingest path (template, parser, or app import).
When another format fits better
- Runtime APIs rarely ingest YAML directly—JSON is the common wire format.
- Strict tabular analysis belongs in CSV/XLSX before you commit YAML to Git.
- When indentation risk is high, JSON can reduce foot-guns for occasional editors.
- Binary or heavy media should not be forced through YAML text channels.
