Frequently Asked Questions

CSV enables analysis in Excel, Google Sheets, and BI tools. Convert YAML config arrays, test data, or API responses to spreadsheet format for reporting, filtering, and data analysis.

Nested YAML structures are flattened using dot notation. For example, {user: {name: 'John', email: 'john@example.com'}} becomes columns 'user.name' and 'user.email'. This preserves structure while remaining CSV-compatible.

YAML arrays within objects are joined with semicolons by default (e.g., tags: ['dev', 'ops'] becomes 'dev; ops'). Top-level YAML arrays of objects are converted to CSV rows automatically.

Complex nested arrays and deeply hierarchical structures may lose fidelity. YAML comments are removed. Multi-document YAML is converted as separate sections. For complex structures, consider JSON export instead.

Choose comma (standard CSV), semicolon (European Excel), tab (TSV), or pipe. Semicolon works best for regions where comma is the decimal separator.

Fields containing delimiters, quotes, or newlines are automatically quoted and escaped following RFC 4180 CSV standards. Enable 'Quote all values' to force quoting on every field.

Yes. The output is fully compatible with Excel, Google Sheets, and LibreOffice Calc. Select the appropriate delimiter for your region (comma for US, semicolon for Europe).

UTF-8 encoding preserves international characters and emoji. Excel 2016+ opens UTF-8 CSV files correctly. For older Excel versions, use the import wizard.

Yes. Multiple YAML documents separated by '---' are parsed and converted. Each document's objects are included as rows in the CSV output.

Yes. Invalid YAML will show an error message with the line number and description, helping you debug formatting issues before conversion.
