Creating Hyperlink in Excel and setting Cell Format

[Heinz Müller]

Hi!

I know how to create a new Excel Document in C# and how to fill the
WorkSheet with data.

But i didn't found any informations how i can insert a hyperlink (for
example to http://www.google.com) and how to set the format of a
cell/column!

As i see, every value i insert into Excel from C# is inserted as Standard
Format, which seems to be just Text. But i need to format some column as
decimal or integer and insert a Link which is click-able from Excel. If i
insert a Link into Excel manuel, it will recognised as Link. But when i
insert a Link with the C# Automation it is just a Text.
Thanks for your help
Heinz
