If I understand your situation correctly, instead of concatenating the values directly to SQL statement you should use parameters in the insert statement.

Have a look at the examples in Properly executing database operations[^]

Simple: Never concatenate strings to build a SQL command. It leaves you wide open to accidental or deliberate SQL Injection attack which can destroy your entire database. Use Parametrized queries instead.
Convert your Excel value to a DateTime - assuming it comes in from Excel as a string, which it shouldn't - and pass the Datetime value directly to SQL via a parameter instead of converting it to a string.
