OK, then why did you not tell us what the win32com.client does? > I'm currently importing a text file into Access.

That's a 32-bit integer. You need to be storing this as a 32-bit integer, not as a string. Or, best of all, as an Access date/time datatype. Exactly which data type in the SQL Server column? How was the text file generated? In virtually every case, SQL Server will export date and time columns as date time strings (that is, "2018-12-17".

Which then gets interpreted by Access. Which version of Python are you using? You are taking binary data and shoving it through a Unicode-to-ASCII conversion. That produces garbage. That's not a string. It's an integer. > Below is a sample of how the sql server timestamp value is stored in Access: > > SQL Server (Timestamp) | Access (Text 50) 0x000000000189CF01 | 003F49 > 0x000000000189D001 | 003F69 0x0000000001B54DFF | 003F6D > 0x0000000001F74701 | 003F4E 0x000000000189C003 | 003F70 > So it tries to do a mapping, sometimes 1 to 1, sometimes not as page 5 of the > below link demonstrates Right. You're producing garbage. The "3F" in there is the "?" character, which means "this character does not exist in the current 8-bit code page". It's not a Unicode string, don't try to treat it like one. — Tim Roberts, t...@probo.com Providenza & Boekelheide, Inc.
