Hi. I am developing content for English learners online.

I am creating a lot of content but sometimes I need to update it, by adding extra info.

The excel
Column A: Keyword or expression.
Column B: A definition
Column C: I need to insert information
Column D: The keyword that need to be "looked up" in column A.
Column E: The text that needs to be inserted in Column C - when keyword match is found.

I will enclose the excel next.
