Comment effacer le contenu d'une cellule dans Excel avec C# | IronXL

This video shows how to merge cells in Excel without losing data using C# and IronXL. It walks through combining a range of cells while keeping the existing values in place, so headers, labels, and layouts survive the merge. That matters when you are generating clean reports, dashboards, invoices, and other formatted spreadsheets from code. IronXL works with the workbook directly, so there is no Interop and no Excel installation to worry about, and the same technique applies anywhere you format spreadsheets in .NET.
