How to use Replace function to replace and add string in Excel?

In Excel, we may use the Find and Replace function to find a string then replace with another one. But in many cases, the Find and Replace function cannot satisfy your request. Here I introduce how to use the Replace function to solve some problems in Excel.

Case 1 Replace character string in the specific location with other in a string

you can do as this:

Select a cell which you will place the result and type=REPLACE(A1,3,3,"KTE"), and drag fill handle over the cells you use. See screenshot shown.

Case 2 Replace multiple character strings in multiple locations with others in a string

=REPLACE(REPLACE(text,stratnum,characternumber,"newtext"),startnum,characternumber,"newtext)

Case 3 Replace year/mont/day in Date format

=REPLACE(TEXT(text, "dd-mmm-yy"), 4, 3, "newtext")
