You can NOT change the column indicator to text of your choice. You can put
a label in the first row and hide the column/row indicators.

The column letters A,B,C etc. cannot be changed.

You can enter titles in row 1 for each column then turn off the Row and Column
headings at Tools>Options>View

Select A2 and Window>Freeze Panes to keep your titles in place as you scroll
down.

There really are two parts to this question,   You have how to
display the top rows and/or left most columns,  but there is also printing
which is controlled from   File, Page Setup,  Sheet,
    Rows to repeat at top:   $1:$1
   Columns to repeat at left: $A:$A

There is a bit more leeway in what you can do in printing.

I don't know what you really tried in your query of Google.
There are two types of Google Searches that are relevant.
Google  web search
and Google newsgroups search of Excel newsgroups
    http://www.mvps.org/dmcritchie/excel/xlnews.htm

Search arguments similar to the following would probably have
yield useable results -- pretty much trying to use words you used.

   Excel column title* worksheet

I think Google will normally equate the single form and the plural forms
of words, but   title*   would pick up   anything beginning with "title" or
the complete word "title".
