I am looking for a formula that will identify the position of the last letter in a cell, ignoring punctuation and special characters.
E.g. If the text in a cell is:
This,text,in,a,cell,,,,,,
The result should be 19 as the last "L" is in position 19. It should ignore all the commas at the end.
 
if result is ok, you can use Power Query (Get&Transform)
Code:
// Table1
let
    Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
    Replace = Table.ReplaceValue(Source,"...","###",Replacer.ReplaceText,{"Raw"}),
    LastChar = Table.TransformColumns(Table.AddColumn(Replace, "Text", each Text.Select([Raw],{"a".."z","A".."Z"})), {{"Text", each Text.End(_, 1), type text}}),
    Position = Table.SelectColumns(Table.AddColumn(LastChar, "Position", each Text.PositionOf([Raw], [Text], Occurrence.Last)+1),{"Text", "Position"})
in
    Position
