Delete rows in multiple files using criteria in a seperate workbook

**ian.cook** · 09-11-2012, 03:09 AM

Hi everyone,

I'm new to this forum and to VBA, so your help would be greatly appreciated!

First-off, I'm using Windows XP and Excel 2003 SP3.

The setup: A software application I regularly use produces csv data files (in this case approx 300 files). These I have converted to xls format using a separate macro. The files are in one folder and named as follows eg

G1 18800.xls
G1 18802.xls
G2 18975.xls
G3 19881.xls
G3 19990.xls
G5 19990.xls
etc

The files contain the following data:

DATE TIME VALUE STEPS EXCL ACCEL
01-Oct-03 08:00 0 0 FALSE 0
01-Oct-03 08:01 0 0 FALSE 0
01-Oct-03 08:02 0 0 FALSE 0
01-Oct-03 08:03 0 0 FALSE 0
01-Oct-03 08:04 757 20 FALSE 0.18
01-Oct-03 08:05 1714 32 FALSE 0.44
01-Oct-03 08:06 1524 32 FALSE 0.39
01-Oct-03 08:07 1665 45 FALSE 0.47
01-Oct-03 08:08 1644 42 FALSE 0.46
01-Oct-03 08:09 263 8 FALSE 0.06
etc

I then created a macro using code I sourced from the internet, and included some addtional commands (filename, copy/paste). See below. This macro opens the all the xls data files in the folder and copies the relevant data to an analysis workbook [Analysis sheet, Results sheet, Master sheet] ie the data is copied from the data file and pasted into the Analysis worksheet. Then the results are copied from the Results sheet to the Master sheet. So far everything works.

My problem is this: I'm stumped at how to delete rows from the xls data files before running the analysis workbook and macro. In other words, after converting the csv files to xls format I need to clean the xls data files.

I have a separate xls file with criteria data in two columns:

FileName Date
G1 18800 06-Oct-03
G1 18801 02-Oct-03
G1 18801 03-Oct-03
G1 18801 05-Oct-03
G2 18795 14-Oct-03
G2 18795 15-Oct-03
G2 18795 16-Oct-03
G2 18795 17-Oct-03
etc

The rows in a particular data file, with dates that are not present in the Criteria workbook must be deleted. This to be done for every data file in the folder. Also, I need to
exclude rows for specific time periods eg 12H00AM - 04H00AM from all the files irrespective of date. I'd be most appreciative of the code needed [should a separate macro be run or can code be placed within the present macro?]. I've tried looking for something similar on the internet but have not been able to find something that I could adapt with my current skill level.

Your assistance would save an enormous amount of time cleaning manually!

Thanks!
Ian
