What is YAML to Excel Converter?

This tool converts YAML to an Excel-compatible spreadsheet. YAML arrays of objects become spreadsheet rows with typed columns. Nested objects are flattened using dot notation. The output is an .xls file that opens in Excel, LibreOffice, and Google Sheets, or a plain CSV file.

How to Use YAML to Excel Converter

1

Paste YAML into the input panel.

2

Set a sheet name.

3

Toggle header row and nested object flattening.

4

Click Download .xls or Export as CSV.

5

Preview the table in the browser.

Common Use Cases

  • Exporting a YAML API response to Excel for data analysis.
  • Converting YAML config arrays to a spreadsheet for review.
  • Producing a CSV from a YAML data file for import.
  • Sharing YAML data with non-technical stakeholders via Excel.

Example Input and Output

A YAML list of users becomes an Excel table.

YAML input
- name: Alice
  age: 30
- name: Bob
  age: 25
Excel rows (name, age)
name  | age
Alice | 30
Bob   | 25

Note

The .xls output uses an HTML-based spreadsheet format. For native .xlsx, open in Excel and save as .xlsx.

Frequently Asked Questions

What YAML structures convert best?
Arrays of objects (a YAML list where each item is a mapping) convert cleanly to rows. A single object becomes a one-row spreadsheet.
Can I open the .xls in Google Sheets?
Yes. The file uses an HTML-based format that Excel, LibreOffice, and Google Sheets can open.
Is my YAML sent to a server?
No. All YAML parsing and conversion happen in your browser.
