Hello manchu,
The following formula(s) will change the case to your desired case. Keep in mind, if you plan on using the converted case from the formula's, be sure to select the cell with the case converted and copy, then paste special Values in another cell.
To change case with a formula, insert a blank column next to the column whose case you wish to change. In that column enter one of the following formula's, depending on what case you want as the result. Change the reference A1 to the first cell in your range.
=UPPER(A1)
=LOWER(A1)
=PROPER(A1)
Exercise:
Make columns A, B, C a column width of 32
A1 Case
B1 Converted Case
C1 Paste Special (Values)
A2 lower to upper
B2 =UPPER(A2)
C2 Paste special (Values) from column B formulas
A3 UPPER TO LOWER
B3 =LOWER(A3)
C3 Paste special (Values) from column B formulas
A4 lower/upper TO sentence CASE
B4 = PROPER(A4)
C4 Paste special (Values) from column B formulas
Hope this helps,
