C# Excel Interop: How to format cells to store values as text

Question

I\'m writing numbers to an Excel spreadsheet from a DataTable and all of these numbers are 5 digits long with preceding 0s if the number itself is less than 5 digit

Answer 1

You can SomeRange.NumberFormat = "@"; or if you prefix the value with a ' and write it to the cell excel will treat it as a number-stored-as-text and provide a visual cue.
