Import selected text file records into Access

I need to import into an Access table selected segments of selected data records that are saved in a text file.The text file has a lot of garbage records and data within each record not useful to me that I need to skip over.

In plain English, this is what I need to accomplish:

1. Read the text file from top to bottom
2. If bytes 1 thru 9 = 'Marketing', then import bytes 1 thru 9 of that record into Field1 of the table and bytes 30 thru 40 of the same record into Field2 of the table. Otherwise skip the record.

Thank you.

Sometimes you can clean up a file if you import it into Word and use Word's Search and Replace feature to do the cleanup -- then re-save it as a clean text file for import into Access.

Often the best way is to import the file into a temporary or "staging" table, and then perform your data validation using SQL and VBA. Once you've validated the records, you can then move them over to the live tables.

If this is a one-time deal, then you can just use the Access interface to import the Text file.  I'm not sure what sort of table structure you'd end up with - that depends on what sort of file you're working with, and how you import it - but if the first Field of your Staging table is the one that contains the "Market" word, then you could just do this:

Currentdb.Execute("INSERT INTO YourLiveTable(Field1, Field2, Field3) (SELECT Col1, Col2, Col3 FROM YourStagingTable WHERE Col1='Market'")

Of course, how you do this depends entirely on the file structure and such. If you could post an example file, perhaps we could provide more information.

All the examples I have are way too complicated to post here.  Look for the syntax for -
Open .... For Input
and
Line Input #FileNum, strLine

To see how to read a text file.

Basically, you have to get a FileNum, Open the file with Open, and then read each record with Line Input.  Beyond that, you're on your own and it depends on the format how you have to process the records.

I'll try to post an example of the type of text files I deal with in a bit.

By the way, I had already tried importing the file directly into a new Access table for it to act as a staging area for further processing. The problem I had with that method is that in my source file, there is a debit column and a credit column.  When I import the text file, both of those columns wind up being combined into one field in Access instead of staying separate.  I can import the file into Excel first but I wind up having to move the verticle lines around manually in the Text Import Wizard window to get them where I need to be. I'm trying to automate the process as much as possible so that I don't always have to deal with manually moving those lines around before importing.

There is no easy way to import a file with inconsistent row formats which is what it sounds like you have.  If you have debit and credit fields on different rows, your code will need to combine them into one row as you are looping through the import file.
