John,
None of my fields in my table have the name "month", they are named Unit, January, February, March, etc. in my new table and the records are the Units #'s.
In the 10 spreadsheets I have a column "Unit" and "Current", the months are not listed in the spreadsheets. Current is the column the mileage is stored in. Every month we added a couple of new units, so no monthly spreadsheet is the same. I need to figure out how to append each monthly spreadsheet so the new units are included w/mileage and not create duplicate records.
Tiffany

Tiffany-
That shouldn't be necessary. I gave you the table design below. But you should avoid a field name Month because that's also a function. Use YearMonth instead. If you import spreadsheet data that has the months across, you can load your table with a series of Append queries:
INSERT INTO tblMonthMileage ([Unit#], YearMonth, Reading)
SELECT [Unit#], "201101" As YearMonth, [Jan]
FROM ExcelTable;
Run that query 12 times - once for each month.

John,
Can I send the table to you? I am not sure how to apply what you are saying.

Yes, it's wrong. Each month should be in its own *record*. Eventually you can use a Crosstab query to "pivot" the data into a spreadsheet format.

Hi John,
12 columns (text) one for each month Plus one column "Unit" (the Key). Mileage is in each month. I have to use text instead of numbers because some units do not have mileage NA is listed in those fields.
Is this wrong?

Tiffany-
What is in Jan-Dec? A number? Is it a mileage reading? Your table should look
like:
Unit#
Month (as in YYYYMM)
Reading
Running columns across that should be individual rows is a relational database
design no-no. (The months are a repeating group.)

I have created a table and I need to populate the data from multiple
spreadsheets.
The table has 13 columns Unit# & Jan-Dec. Over the course of the year we have
added units, so every month the spreadsheet has changed and columns have been
added or deleted as well.
I do not need all the information from the spreadsheets, just the "unit" column
and the "Current" column imported into my database.
Is there an easy way to pull all this information into one spreadsheet and keep
it constrained to the unit number?
