CSV → YAML — spreadsheet rows to GitOps lists

Great when analysts ship CSV but platform wants indented YAML reviews.

Developer notes

• Scalar casting still manual — YAML receives strings. • Align quoting mode with team style guides.

When teams pick this route

• Support exporting ticket CSV into Ansible-friendly lists. • Teaching how tabular data nests visually.

About these options

CSV exports: choose a delimiter (Auto follows locale — semicolon on /fr), RFC-minimal vs always-quoted fields, line endings, and whether to emit a header row. CSV imports: delimiter is auto-detected from the first line (comma, semicolon, tab, or pipe) — toggle whether row 1 holds column names. JSON output (XML, YAML, or CSV sources): indentation (including compact one-line) and optional recursive key sort. JSON → XML: toggle pretty-printing and indent width. YAML output: indent width, readable vs tighter layout, and deterministic string quoting (there is no source YAML file to “preserve”). XML comments are not represented in the intermediate JSON tree.

Emitter nuances

Quoted scalars?

Controlled via YAML string quoting options — deterministic, not source-preserving.

Maps vs lists?

Uniform rows become sequences of mappings.

Comments?

Add manually after conversion.

Delimiter mistakes?

Mis-selected delimiter yields noisy warnings — adjust CSV input options.
