Why convert CSV to YAML?

You exported a spreadsheet and need a config-friendly format. YAML keeps the tabular data readable while fitting into pipelines that prefer YAML over CSV.

What changes in the output

  • CSV rows become a YAML list of objects
  • All values remain strings from the sheet
  • Header row defines object keys
  • No nested structure is inferred beyond flat columns

How to convert CSV to YAML
