Different languages collision in one function.

Hello,

I have to work with protected document without macros and I can not find its author.

It is created in German language, but I want to open document and edit with my language.

There is an original formula in locked cell

=ZELLE("Inhalt";A1)

When I open it with English default language, the parameter of function remains in German

=CELL("Inhalt";A1)

But it should be

=CELL("Contents";A1)

Is any way how to fix it?

Is any possibility to change "CELL" function definition using VBA without changing the document?

Thanks for reply

Kamil
