Hi, I have put together this code to hide all blank cells in certain Row ranges across an array of worksheets.
It works ok, but it seems to take some time to complete and uses alot of computer resources to run.
Is it possible to use alternative VBA code to be more efficient and speed up the execution time and reduce the CPU/RAM usage?

VBA Code: 
Sub HideBlankRowsAllTabs()

sheetlist = Array("MS002", "MS003", "MS004", "MS005", "MS006", "MS007", "MS008", "MS009", "MS010", "MS011", "MS012")
For i = LBound(sheetlist) To UBound(sheetlist)
Worksheets(sheetlist(i)).Activate

For Each cell In Range("A330:A386")
  If cell.Value = "" Then cell.EntireRow.Hidden = True
    Next cell
   
For Each cell In Range("B293:B296")
  If cell.Value = "" Then cell.EntireRow.Hidden = True
    Next cell
 
For Each cell In Range("B232:B288")
  If cell.Value = "" Then cell.EntireRow.Hidden = True
    Next cell

For Each cell In Range("B197:B207")
  If cell.Value = "" Then cell.EntireRow.Hidden = True
    Next cell
 
For Each cell In Range("B176:B188")
  If cell.Value = "" Then cell.EntireRow.Hidden = True
    Next cell

Next
End Sub

I have a similar code to reverse the operation and unhide the rows in which I just changes the "True" to "False".

Also, is there syntax that can be added that autofits the rows/cells to the content when unhiding the rows?

Thanks

try this, I have used a varaint array to reduce the number of access to the workhseet in the loop:
VBA Code: 
Sub HideBlankRowsAllTabs()

sheetlist = Array("MS002", "MS003", "MS004", "MS005", "MS006", "MS007", "MS008", "MS009", "MS010", "MS011", "MS012")
For i = LBound(sheetlist) To UBound(sheetlist)
'Worksheets(sheetlist(i)).Activate
Worksheets(i + 1).Activate
inarr = Range(Cells(1, 1), Cells(386, 2))
'For Each cell In Range("A330:A386")
For j = 386 To 330 Step -1
'  If cell.Value = "" Then cell.EntireRow.Hidden = True
    If inarr(j, 1) = "" Then Cells(j, 1).EntireRow.Hidden = True
    Next j
   
'For Each cell In Range("B293:B296")
   For j = 296 To 293 Step -1
 '  If cell.Value = "" Then cell.EntireRow.Hidden = True
    If inarr(j, 2) = "" Then Cells(j, 1).EntireRow.Hidden = True
    Next j
    'For Each cell In Range("B232:B288")
   For j = 288 To 232 Step -1
    If inarr(j, 2) = "" Then Cells(j, 1).EntireRow.Hidden = True
    Next j

   'For Each cell In Range("B197:B207")
   For j = 207 To 197 Step -1
    If inarr(j, 2) = "" Then Cells(j, 1).EntireRow.Hidden = True
    Next j
 
'  For Each cell In Range("B176:B188")
   For j = 188 To 176 Step -1
    If inarr(j, 2) = "" Then Cells(j, 1).EntireRow.Hidden = True
    Next j

Next
End Sub

How about:

VBA Code: 
Sub HideBlankRowsAllTabs()
'
    sheetlist = Array("MS002", "MS003", "MS004", "MS005", "MS006", "MS007", "MS008", "MS009", "MS010", "MS011", "MS012")
'
    For i = LBound(sheetlist) To UBound(sheetlist)
        Worksheets(sheetlist(i)).Activate
'
        On Error Resume Next
'
        Range("A330:A386").Cells.SpecialCells(xlCellTypeBlanks).EntireRow.Hidden = True
        Range("B293:B296").Cells.SpecialCells(xlCellTypeBlanks).EntireRow.Hidden = True
        Range("B232:B288").Cells.SpecialCells(xlCellTypeBlanks).EntireRow.Hidden = True
        Range("B197:B207").Cells.SpecialCells(xlCellTypeBlanks).EntireRow.Hidden = True
        Range("B176:B188").Cells.SpecialCells(xlCellTypeBlanks).EntireRow.Hidden = True
'
        On Error GoTo 0
    Next
End Sub

Thanks Johnny, this works perfectly.

How do I unhide all the hidden rows?
Ive tried changing True to False but that doesnt seem to unhide all the rows which has formulae in them.
It works for the blank rows and the rows with validation dropdown boxes, but if the referenced cell has a formulae, it doesnt unhide those rows.
Any ideas?

Thanks for your help but this seems to not limit itself to the specified worksheet tab array and does all the tabs in the workbook.

Did you try:

VBA Code: 
Cells.EntireRow.Hidden = False
Click to expand...
That seems to work, thanks Johnny.

The previous code to hide all the cells worked perfectly earlier today but when I try it now it doesnt work, it doesnt hide ALL the blank cells with formulae in them. It works on the other cells which is just text. I havent made any changes to the document. Do you know what the issue could be?
I have tried changing the code to:
VBA Code: 
cells.EntireRow.Hidden = True
but this didnt seem to do anything.

Hi Johnny,

Ive had to amend the macro to only operate on the active sheet rather than the array of worksheets.
This is the syntax mod I made:

VBA Code: 
Sub HideBlankRowsThisWorksheet()
'
Dim ws As Worksheet
Set ws = ActiveSheet

        On Error Resume Next
       
        ws.Range("A348:A404").Cells.SpecialCells(xlCellTypeBlanks).EntireRow.Hidden = True    'RA Table
        ws.Range("B311:B314").Cells.SpecialCells(xlCellTypeBlanks).EntireRow.Hidden = True    'COSHH
        ws.Range("B250:B306").Cells.SpecialCells(xlCellTypeBlanks).EntireRow.Hidden = True    'RA List
        ws.Range("B215:B226").Cells.SpecialCells(xlCellTypeBlanks).EntireRow.Hidden = True    'Materials
        ws.Range("B194:B206").Cells.SpecialCells(xlCellTypeBlanks).EntireRow.Hidden = True    'P&E
        ws.Range("B132:B175").Cells.SpecialCells(xlCellTypeBlanks).EntireRow.Hidden = True    'Sequence of Works 2
        ws.Range("B104:B125").Cells.SpecialCells(xlCellTypeBlanks).EntireRow.Hidden = True    'Sequence of Works 1
'
        On Error GoTo 0

End Sub


Annoyingly, this doesn't seem to work correctly even though the syntax is showing as correct in VBA editor.

Any referenced cells which has a blank value due to an IF formula true result of "", will not hide, it just hides the entire range specified.
These are the rows / ranges which have the issue:

VBA Code: 
ws.Range("A348:A404").Cells.SpecialCells(xlCellTypeBlanks).EntireRow.Hidden = True    'RA Table
ws.Range("B250:B306").Cells.SpecialCells(xlCellTypeBlanks).EntireRow.Hidden = True    'RA List

Any referend cells which are either blank for manual typing or blank with validation dropdown boxes unselected work fine.

If I revert to my original code below, it works on all referenced cells/rows, but its painfully slow to run:

VBA Code: 
For Each cell In Range("A348:A404")
  If cell.Value = "" Then cell.EntireRow.Hidden = True
    Next cell
      
For Each cell In Range("B311:B314")
  If cell.Value = "" Then cell.EntireRow.Hidden = True
    Next cell
    
For Each cell In Range("B250:B306")
  If cell.Value = "" Then cell.EntireRow.Hidden = True
    Next cell

For Each cell In Range("B215:B226")
  If cell.Value = "" Then cell.EntireRow.Hidden = True
    Next cell
    
For Each cell In Range("B194:B206")
  If cell.Value = "" Then cell.EntireRow.Hidden = True
    Next cell

For Each cell In Range("B132:B175")
  If cell.Value = "" Then cell.EntireRow.Hidden = True
    Next cell
    
For Each cell In Range("B104:B125")
  If cell.Value = "" Then cell.EntireRow.Hidden = True
    Next cell
    
Next



Any idea what maybe causing the issue?


Thanks

Did you ever try my code from post #2 which is a slight modification of your code and should work the same way but work a bit faster

This one?

VBA Code: 
Sub HideBlankRowsAllTabs()

sheetlist = Array("MS002", "MS003", "MS004", "MS005", "MS006", "MS007", "MS008", "MS009", "MS010", "MS011", "MS012")
For i = LBound(sheetlist) To UBound(sheetlist)
'Worksheets(sheetlist(i)).Activate
Worksheets(i + 1).Activate
inarr = Range(Cells(1, 1), Cells(386, 2))
'For Each cell In Range("A330:A386")
For j = 386 To 330 Step -1
'  If cell.Value = "" Then cell.EntireRow.Hidden = True
    If inarr(j, 1) = "" Then Cells(j, 1).EntireRow.Hidden = True
    Next j
   
'For Each cell In Range("B293:B296")
   For j = 296 To 293 Step -1
 '  If cell.Value = "" Then cell.EntireRow.Hidden = True
    If inarr(j, 2) = "" Then Cells(j, 1).EntireRow.Hidden = True
    Next j
    'For Each cell In Range("B232:B288")
   For j = 288 To 232 Step -1
    If inarr(j, 2) = "" Then Cells(j, 1).EntireRow.Hidden = True
    Next j

   'For Each cell In Range("B197:B207")
   For j = 207 To 197 Step -1
    If inarr(j, 2) = "" Then Cells(j, 1).EntireRow.Hidden = True
    Next j
 
'  For Each cell In Range("B176:B188")
   For j = 188 To 176 Step -1
    If inarr(j, 2) = "" Then Cells(j, 1).EntireRow.Hidden = True
    Next j

Next
End Sub


I am using a macro button on each worksheet rather than doing all specified tabs together as it give flexibility using my document.#

How do I amend you code to work for the active sheet only?

Thanks
