Delphi/Excel connection problems

I am connecting through ADO Connection and Query to Excel workbook. I have two problems.


1/ The Excel workbook comes to me with spaces in the column titles. Within Delphi is it possible to delete the spaces or change the column names?

2/Having changed the Excel column names manually, I am able to connect and sort the workbook sheets. The workbook appears in a connected DBGrid. However, when I run the following code adoquery1.first; X:=adoquery1['fieldname'].Asstring; label1.caption:=x; I get the following error "Variant does not reference an automation Object' So I need solutions to these two problems, please.

var columnname: string;
columnname := Trim(columnname);  // will remove spaces before and after

X:=adoquery1['fieldname'].Asstring  << error, use either
X:=adoquery1['fieldname']  or   X:=adoquery1.FieldByName('fieldname').AsString
the square brackets return a Variant right away, so no need for AsString.

Sorry I should have said the spaces in the column names are in the middle, ie "Test Results". I can't seem to do anything with the table unless I manually delete the spaces to make
"testresults".
