Stop CSV Data From Being 'Fixed' When Opened in Excel — Control Encoding and Column Types in Your C# App
ZIP code 01950 becomes 1950, product code 1-2-3 becomes a date, and a UTF-8 file shows up as garbled text — CSV breaks because the file carries no type information and whatever opens it guesses. In your own app, you declare the encoding and the per-column types. Build a CSV viewer / importer in C# with ReoGrid that doesn't corrupt your data.
