C# OpenXML Sort Excel on Multiple Columns

Question

I am looking for example code on how to sort an Excel sheet, using OpenXML, on multiple columns in C# .Net 6.

I have a handle on my spreadsheet:

using SpreadsheetDocument spreadSheet = SpreadsheetDocument.Open(path, true);

I need to sort columns by:

• "Project" a to z
• Then By "Employee" a to z
• Then By "Item" a to z
• Then By "Start" oldest to newest (Date)

I have found very little documentation on how to do this.
