YAML to CSV Conversion Example

Input: YAML Array of Records
- id: 1 name: Alice dept: Engineering - id: 2 name: Bob dept: Product
Output: RFC 4180 CSV Spreadsheet
1id,name,dept
21,Alice,Engineering
32,Bob,Product

Nested YAML vs Flattened Columns

Raw Unflattened Object Columns
1name,address
2Alice,"{""city"":""SF"",""state"":""CA""}"
Unflattened objects are crammed as JSON strings inside a single cell, making spreadsheet filtering difficult.
Clean Flattened Dot-Notation Columns
1name,address.city,address.state
2Alice,SF,CA
