Is it technically possible to flip numbers from all cells in a column without a plugin ?
For example, a two column spreadsheet with
Ref, Weight
3300, 500
3200, 500
Would become
Ref, Weight
0033, 500
0023, 500
Select the cells you wish to process and run this short macro:
Sub flipper()
Dim r As Range, s As String
For Each r In Selection
r.NumberFormat = "@"
r.Value = StrReverse(r.Text)
Next r
End Sub
Macros are very easy to install and use:
If you save the workbook, the macro will be saved with it. If you are using a version of Excel later then 2003, you must save the file as .xlsm rather than .xlsx
To remove the macro:
To use the macro from Excel:

Macros must be enabled for this to work!
EDIT#1:
If you wish to avoid macros and the cells contain only digits and you are willing to use a "helper column", then with digits in column A, in C1 enter:
=TEXT(SUMPRODUCT(MID(A1,ROW(INDIRECT("1:" & LEN(A1))),1)*10^(ROW(INDIRECT("1:" & LEN(A1)))-1)),REPT("0",LEN(A1)))
