## Tips & Tricks 158 - Overcoming column_index_number problem in VLOOKUP when a column is inserted / deleted

By |Saturday, April 08th, 2017|Categories: Tips and Tricks||0 Comments

One of the negative points which gets attributed to VLOOKUP is that whenever a column is added / inserted within the range of VLOOKUP, the column index number doesn't change. Hence, it gives wrong result. Let's consider below dataset and for a given Emp ID, I need gender of that person. Hence, for Emp ID, 754761, the formula would be =VLOOKUP(754761,\$A:\$G,6,0) and answer would be F. Now, let's delete a column and now the answer would be lelia.vang@gmail.com as column_index_number is still 6. Now, add a column and the answer would be Vang as column_index_number is still 6.

## Tips & Tricks 124 - VBA - Check if a Range is Blank When Range Contains Formulas returning Blanks

By |Saturday, December 26th, 2015|Categories: Tips and Tricks, VBA|Tags: , , , , , , |0 Comments

In VBA, often, we have situations where we need to check if a range is blank or not. The popular formula which we see following is used to check whether range is blank or not.

WorksheetFunction.CountA(Range("A1:A100"))

```Sub CheckifBlank()
If WorksheetFunction.CountA(Range("A1:A100")) Then
MsgBox "Range is Not Blank"
Else
MsgBox "Range is Blank"
End If
End Sub```

But if your range contains even a single formula which is returning blank, the above will not return the range as blank even though it contains literal blanks.

To handle this, you can use below to check if your range is blank even though the range contains formulas returning blanks.

Range("A1:A100").Rows.Count = WorksheetFunction.CountBlank(Range("A1:A100"))

```Sub TestBlanks()
If Range("A1:A100").Rows.Count = WorksheetFunction.CountBlank(Range("A1:A100")) Then
MsgBox "All Blanks"
Else
MsgBox "Not All Blanks"
End If
End Sub```

## Tips & Tricks 41 - I have data for many years but I want the sum for only last 12 months

By |Saturday, August 16th, 2014|Categories: Tips and Tricks|Tags: , , , , |0 Comments

Let's assume that your data is aligned like this and you want to have sum only for last 12 months. This should take care of if future entries are done. Hence, if Jun data is entered, sum up has to start from Jun month. - Use this formula -

=IFERROR(SUM(OFFSET(INDIRECT("\$B"&COUNTA(\$A:\$A)),0,0,IF(COUNTA(\$A:\$A)-12>0,-12,-COUNTA(\$A:\$A)+1),1)),"")

Note - If you have only one column say B, replace \$A with \$B. (If only A, replace \$B with \$A)
