Today's TechHelp tutorial from Access Learning Zone is all about managing field names when importing data into Microsoft Access from Excel or a text file. I am your instructor, Richard Rost. Often, the field names in imported data can cause issues, such as errors indicating that an item is not found in a collection. Today, we'll discuss how to handle these situations.
A member recently encountered error 3265 while importing a spreadsheet, where Access couldn't find a specific field in the collection despite its apparent presence. After some troubleshooting, it was apparent that a common cause for such issues is incorrect naming conventions in field names. This includes having spaces or non-standard characters in the field names.
In the field's design view, Access usually prevents having trailing spaces in field names. However, if you import data from an external source, such as a spreadsheet, trailing spaces might still accompany field names, leading to errors. Someone else might have originally created the spreadsheet or file, and you might not have the luxury of correcting field names manually.
A brilliant suggestion from one of our contributors was to look for a trailing space after the field name. Indeed, when you import data using Visual Basic for Applications (VBA) and the TransferSpreadsheet method, Access may retain these trailing spaces. This doesn't occur if you import manually via the Access interface, which trims such spaces automatically.
To illustrate, let's say you have a spreadsheet with fields for first name, last name, and phone number. Suppose there's an inadvertent space after the "last name" field. If you import this using VBA, Access keeps the trailing space. When trying to access the field in a VBA recordset, the trailing space causes an error.
To resolve this, you can account for the space within your code by including it in the field name reference. Alternatively, once imported, you can adjust the field names using VBA to remove trailing spaces or correctly match them as needed. This can be achieved by examining the field names and modifying them through VBA programming, which is covered more extensively in my developer classes.
If it's possible to do so, the simplest fix is to modify the original spreadsheet field names before importing. However, when constraints exist, ensure your code accounts for any discrepancies.
A quick note for those following the employee training series: I've recently updated it, and more lessons are on the way. I expected to finish recording the upcoming sessions soon.
