回答1:

Return everything before the first space character:

=left(A1, find(" ",A1&" ")-1)

This formula also works if there is no space in the source text.

回答2:

If the end of the text is always " is a pdf containing important stuff", you could use the following formula:

=LEFT(A1, LEN(A1) - 36)

Make sure you replace "A1" with the reference to the cell you need to extract the value from.

回答3:

This will return the document name regardless of the text string after that.

=LEFT(A1; FIND(".pdf";A1)+4)
