Why does the error 'Arithmetic Operation Resulted in an Overflow' occur when reading data from Excel?

Issue Description:
This error can be encountered when reading data from a spreadsheet with integer values.
The maximum value for a 32-bit integer is 2,147,483,648, and exceeding this value results in an overflow exception.

Using a 64-bit integer (Int64) with a maximum value of 9,223,372,036,854,775,807, one can avoid overflow issues and handle a broader range of integer values.


Root Cause: Overflow is an operation that occurs when a calculation produces a result that is greater in magnitude than that which a given register or storage location can store or represent.


Resolution:

  • Change the variable type to Int64 (64-bit) instead of Int32 (32-bit).
This may prevent overflow-related exceptions.
Example: use Convert.ToInt64(yourintegervariable.ToString)
