How to Convert Excel XLSX Spreadsheets to PDF in C# and .NET 6

If you have Excel spreadsheets generated from .NET Core applications, you may find it helpful to store your files in a PDF format.

Why do I need to convert an Excel spreadsheet to PDF?

Several reasons include:

  • Storing Excel spreadsheets for long-term preservation.
  • Not having MS Office installed on a system, but still wanting to open, print, or distribute your Excel spreadsheets.
  • Consistency of presentation of Excel spreadsheets when opened on different systems.

Alternatively, you may need to create and distribute the following company reports:

  • Profit & Loss Statement
  • Company Budget
  • Sales Forecast
  • Income Statement

worksheet.PageSetup.Orientation = PageOrientation.Landscape;  
worksheet.PageSetup.IsPercentScale = false;  
worksheet.PageSetup.FitToPagesWide = 1;  
worksheet.PageSetup.FitToPagesTall = 1;
