Question : Access Import of Excel Customized Date Formats into Text Field

Hello EE,

I am using Access 2007 to import an Excel file with dates into a table that is all text fields. (The columns within the Excel files move around and there's a separate process that maps these using a schema.)

My problem is that a user may enter a date into an Excel date field as 11/01/09, but sometimes the users have date "formatted" to look like Nov-09 (mmm-yy). After the import the Access table has the value of "Nov-09". When converting this back to a date it becomes 11/09/2010.

How do I import the underlying date value from Excel (40118) into the Access table's text field, if it exists, so that the proper date can be extracted from that field when that data is reformatted? Hopefully it is just a transferspreadsheet switch.

I am using the following to import:
DoCmd.TransferSpreadsheet acImport, acSpreadsheetTypeExcel9, "tblImportXLS", .Fields("FullFilePath"), False, .Fields("FileTabName")
Thanks,

LVBarnes

Answer : Access Import of Excel Customized Date Formats into Text Field

Hi lvbarnes,

I've created an example for you.

This procedure will take in any xl data file and import to a given table in access.

Required references: (Go to Tools => References...)
Microsoft Office Object Library
Microsoft DAO 3.6 Object Library
Microsoft Excel 11.0 Object Library

CONSTRAINTS!
Data must start in cell A1 (first row can be a header row.)
First row must NOT contain blank cells in column range.
First column must NOT contain blank cells in data range.

(Will only import fields up to the first blank cell in first column and data up to the first blank cell in the first row.)
