Read Excel in Known Format

Hi,
I want to create something that open and read an excel spreadsheet (that part seems easy).
Also to read in the 5 different sheets that should be present is easy.
I know in advance how many columns I will be looking at, and what to expect in each column.
I just dont know know how many rows there will be...first blank one will be the end.
Some code i tired keep running for 65,000 rows.....messing performance up completely.

So simply want some thing that let me read the value in columns say A - X in each row, until column a's value in a certain row is nothing.

I can write it myself if playing around I guess, but really out of time, and the person I hoped was going to do this project (from VBF!!!) seems to have disapeared.

If you just need the data and not any Excel functionality then you should use ADO.NET. You read it just like an Access database, where the file is the database and each sheet is a table. See www.connectionstrings.com fo rthe adjustments you need to make to the connection string and SQL statements.
