Accumulate Data from 10k+ Files. Very Slow. Issue with ActiveWorkbook.Sheets(2).Cells(Rows.Count, 1).End(xlUp).Row

Scope: I have several thousand files (14k right now) that are all in the same identical layout that I want to accumulate the data into one file. It's a collection of velocity testing data. Sheet1 is all single entry data >> one value always. Sheet2 is variable between 1-20 rows of data points. The accumulation of Sheet1 data points is always the same, accumulation of Sheet2 data points is variable.

Sheet 1:
Test: Single Value
Operator: Single Value
Test Date: Single Value
Test Time: Single Value
Gun: Single Value
Mfg / Model: Single Value
Caliber: Single Value
Serial #: Single Value
Powder: Single Value
Powder Wgt: Single Value
Lot Number: Single Value
Avg Velocity: Single Value

Sheet 2:
Rnd: Values are integers varying between 1-20 rows. (Rnd = Vel13 = Prf regarding the number of rows)
Vel13: Values are integers varying between 1-20 rows. (Rnd = Vel13 = Prf regarding the number of rows)
Prf: Values are integers varying between 1-20 rows. (Rnd = Vel13 = Prf regarding the number of rows)
File Name: Single Value


Question Part 1: I am successfully cycling through the files and collecting data for Sheet1. However, my runtime is about 28sec per 100 files. So about 66min at 14k files runtime whenever the sheet is updated. Not really acceptable... How do I speed this up?

Question Part 2: On Sheet2 I need to collect variable data using the Rnd column. See image. Data always begins in A4 so I'm trying to capture the range of (A4:LastRowTestData) using LastRowTestData = ActiveWorkbook.Sheets(2).Cells(Rows.Count, 1).End(xlUp).Row but it's not working. My guess is it's the variable being defined/passed incorrectly. I can run the below in the file I'm opening and it works just fine. When I run it from my "accumulation sheet" it doesn't work.

Dim LastRowTestData As Long
LastRowTestData = ActiveWorkbook.Sheets(2).Cells(Rows.Count, 1).End(xlUp).Row
MsgBox LastRowTestData


End Goal: Open File 1 in selected folder, copy the range of (A4:LastRowTestData), (B4:LastRowTestData), C4:LastRowTestData) from Sheet2 to the Accumulation Sheet under the proper header. Copy the single value data from Sheet1 to Accumulation Sheet. Duplicate the Sheet1 single values on the Accumulation sheet for the Sheet2 data length.

Index to the next file, repeat the process for all files.

How is LastRowTestData different than you expect? If you're copying data from one workbook to another, is the active workbook the workbook you think it is? Your code would be more reliable if you use

VBA Code: 
Dim wbSource As Workbook
Dim wbTarget As Workbook
Set wbSource = Workbooks(source_workbook_name)
Set wbTarget = Workbooks(target_workbook_name)

and then reference the workbooks by these variables, e.g.

VBA Code: 
LastRowSource = wbSource.Sheets(2).Cells(wbSource.Sheets(2).Rows.Count, 1).End(xlUp).Row
LastRowTarget = wbTarget.Sheets(2).Cells(wbTarget.Sheets(2).Rows.Count, 1).End(xlUp).Row

I'm not sure that this will help, but it will overall improve reliability.

Hi smitetha. Jon has offered some great suggestions. Your going through a lot of files so it's better just to load all the source file(s) info into an array and then unload the array all at once to the target wb. Here's some code that you can trial which should significantly speed up Part 1. For Part 2, you can also load ranges into an array and then resize them when you unload them. I don't understand what your source ranges or target locations are? Anyways, trial this untested code to begin with. HTH. Dave

Appreciate the feedback Jon. I went ahead and added the wbSource and wbTarget. wbTarget being Set wbTarget = ThisWorkbook at the very top of the Macro - in order to allow using changing of the file name.

I added wbSource to the lines below, step through them, and everything works fine except the very last line. I get successful values on the first two MsgBox and the error code below for the Row.Count.

I know this line has Sheets(1) and not Sheets(2) but the issue is there for both.

Thoughts?

Will begin working on trying this Dave. Appreciate the help. As I step through getting the code to work, this would be the manual entry flow. This would be for (3) separate source files. File Name.... Group 1, Group 2, Group 3 all consist of single values for each column on Sheet1. The middle section (what I would actually do as step 1) is to bring over the Rnd, Vel13, Prf values which in this example is a Row length of 5, 8, 2. After the Rnd, Vel13, Prf values are populated, I want to Copy Cells for the Source values of Sheet1 to that row length. That way when I filter the headers, all Sheet1 values associated with the Rnd, Vel13, Prf is available.

Dave, was able to get your array coding to work just fine. Made some minor tweaks so that column headers can be changed in one location and it follows through the array. Time for 100files went from 28sec to 20sec. So some improvement. Because the file names are read only on the network server, I could eventually run the program one time to get all the info and skip adding anything new after running it again.

Before I being figuring out the Rnd, Vel13, Prf values, is an array the best approach still? Hopefully the picture I attached makes sense as to what I'm trying to accomplish. I appreciate your help and guidance.

Yes I believe the array approach will be quickest. Where are the ranges?
' = ActiveWorkbook.Sheets(2).Range("A4:& ).Text 'Copy value from Test Data Sheet "Rnd"
' = ActiveWorkbook.Sheets(2).Range("B4:& ).Text 'Copy value from Test Data Sheet "Vel13"
' = ActiveWorkbook.Sheets(2).Range("C4:& ).Text 'Copy value from Test Data Sheet "Prf"
Click to expand...
sheet 2 A4 to last row of A goes to what column in the target wb? Same for B4 to last and C4 to Last? You can load these ranges at the same time as you retrieve the other information. You should be able to output to your final format without any intermediary steps. Dave

Hey Dave, haven't changed my code below to replicate yours but mine is doing everything I want. I have ran up to 1000 files which creates about 4300 rows of data. However, when I move to running all 14k files, I get the below. Left the computer to run by itself. It's a work computer that I use for 3D modeling, so I have to believe it's plenty capable. All the files I'm opening are 9-13kb, Excel 97-2003 worksheet.xls

Any input would be helpful. I'm going to run it again trying to process all of them and add the processed count the the error message to see how many files I actually make it through.

Thanks!
