Microsoft Excel is a powerful tool that can be used for data manipulation. In order to make the most of the software, you need to use VBA. Visual Basic for Applications, or VBA, gives Excel users the ability to create macros, which are powerful time-saving custom functions for data manipulation and analysis.
Macros process VBA code in order to manage large data sets that would otherwise take up a lot of time to modify. For example, with VBA you can create a macro to automatically format certain fields that meet your determined criteria.
Below is an example of a VBA script used in Excel:
Sub ConfigureLogic()
Dim qstEntries
Dim dqstEntries
Dim qstCnt, dqstCnt
qstEntries = Range(“QualifiedEntry”).Count
qst = qstEntries – WorksheetFunction.CountIf(Range(“QualifiedEntry”), “”)
ReDim QualifiedEntryText(qst)
‘MsgBox (qst)
dqstEntries = Range(“DisQualifiedEntry”).Count
dqst = dqstEntries – WorksheetFunction.CountIf(Range(“DisQualifiedEntry”), “”)
ReDim DisqualifiedEntryText(dqst)
‘MsgBox (dqst)
For qstCnt = 1 To qst
QualifiedEntryText(qstCnt) = ThisWorkbook.Worksheets(“Qualifiers”).Range(“J” & 8 + qstCnt).value
‘MsgBox (QualifiedEntryText(qstCnt))
logging (“Configured Qualified Entry entry #” & qstCnt & ” as {” & QualifiedEntryText(qstCnt) & “}”)
Next
For dqstCnt = 1 To dqst
DisqualifiedEntryText(dqstCnt) = ThisWorkbook.Worksheets(“Qualifiers”).Range(“M” & 8 + dqstCnt).value
‘MsgBox (DisqualifiedEntryText(dqstCnt))
logging (“Configured DisQualified Entry entry #” & qstCnt & ” as {” & DisqualifiedEntryText(dqstCnt) & “}”)
Next
includeEntry = ThisWorkbook.Worksheets(“Qualifiers”).Range(“IncludeSibling”).value
‘MsgBox (includeEntry)
logging (“Entrys included in search – ” & includeEntry)
End Sub

How To Analyze and Manipulate Entries in a Spreadsheet
In order to use VBA for data analysis, you will need to check the settings in Excel for the Developer tool. To find it, locate the Excel Ribbon and search for the Developer tab. If it is not displayed, you will need to activate it in the Excel Settings menu.
Next, create a new worksheet and name it “Qualifiers.” We will use this sheet to check for all of the things that qualify the selections.
Next, set up the qualifiers on the sheet according to the code. It must be entered manually; cut and paste will not work.
ThisWorkbook.Worksheets(“Qualifiers”).Range(“J” & 8 + qstCnt).value
How To Locate the Range and Construct an Array
The range in the function above is cell J9. The range function notes an 8; however, the actual range is 9 because:
For qstCnt = 1 To qst
The above statement starts at 1, not 0. Therefore, the list starts at 9. In this case, note (qstCnt=1).
To construct an array out of entries on the Qualifiers worksheet, place random words in cells J9-J13. Once the rows are completed, we can move forward with finding and manipulating data in Excel.
Private Sub CountSheets()
Dim sheetcount
Dim WS As Worksheet
sheetcount = 0
logging ("*****Starting Scrub*********")
For Each WS In ThisWorkbook.Worksheets
sheetcount = sheetcount + 1
If WS.Name = "Selected" Then
'need to log the date and time into sheet named "Logging"
ActionCnt = ActionCnt + 1
logging ("Calling sheet: " & WS.Name)
scrubsheet (sheetcount)
Else
ActionCnt = ActionCnt + 1
logging ("Skipped over sheet: " & WS.Name)
End If
Next WS
'MsgBox ("ending")
ActionCnt = ActionCnt + 1
logging ("****Scrub DONE!")
Application.ScreenUpdating = True
End SubThere is an example of a working tab counter.
Dim sheetcount
Dim WS As Worksheet
sheetcount = 0
logging ("*****Starting Scrub*********")
For Each WS In ThisWorkbook.Worksheets
sheetcount = sheetcount + 1After initialising the sheet count, set it to 0 in order to restart the counter.
Logging() is another subroutine that keeps track of all actions in order to audit selections.
The next For loop sets up the Active Workbook for counting. WS is the initialised and ThisWorkbook. Worksheets is the active tab in the book. Since we have not named the workbook, this module will run on any active workbook. If you are working on multiple workbooks and have the wrong one activated, it will attempt to run on it. To avoid errors, take precautions to name your specific workbook or only work on one at a time.
Every time the loop fires, it adds one variable to the sheet count to keep track of the number of tabs. Then we move to:
If WS.Name = "Selected" Then
'need to log the date and time into sheet named "Logging"
ActionCnt = ActionCnt + 1
logging ("Calling sheet: " & WS.Name)
scrubsheet (sheetcount)
Else
ActionCnt = ActionCnt + 1
logging ("Skipped over sheet: " & WS.Name)
End IfHere, we look for the Selected tab.
If the variable WS is equal to Selected, then we log it and fire the subroutine Scrub Sheet. If the variable WS is not equal to Selected, it is logged that that sheet was skipped and the action is counted. The above code is an example of how to count the number of and locate a particular tab.
The following listng is all of the different methods that can be used to manipulate data!
