#Excel: Remove Multiple Characters From a String Using The TEXTJOIN Function and Without Using the SUBSTITUTE or REPLACE Function

 

There are a number of examples of the removal of characters from a string which utilize nested SUBSTITUTE or REPLACE functions. However, they are hard-coded in that the formulas are built with a set number of characters to remove based on the times that the SUBSTITUTE function is used. The formula methodology I am presenting here is more flexible and robust than previous solutions.

In this example, I am trying to remove all punctuation from a string, specifically the one shown below from cell A1. You will note that this string contains five different punctuation symbols, several occurring more than once.

x,da.”xyz”.c?e!

The following array formula removes those symbols

=TEXTJOIN(“”,TRUE,IF(ISERROR(MATCH(MID(A1,ROW(INDIRECT(“1:”&LEN(A1))),1),{“,”;”.”;”?”;”!”;””””},0)),MID(A1,ROW(INDIRECT(“1:”&LEN(A1))),1),””))

and affords the desired string shown below.

#Excel: Most Frequent Item in a List of Delimited Strings

 

rng is a defined name range on the worksheet with each cell containing delimited strings. Although it does not necessarily have to be a 1-column list, most examples of delimited strings in a range are of this type. To convert this range to an array, use the following formula.

Define arr as =ArrayFromCDS(TEXTJOIN(“,”,,rng))

where the VBA UDF is shown below.

Function ArrayFromCDS(MyString As String)

ArrayFromCDS = Split(MyString, “,”)

End Function

So, arr is a 1-D array of all of the delimited values from each cell of the range. Then, use this formula

=INDEX(arr,MODE(MATCH(arr,arr,0)))

to return the most frequent item.
