If Text.Contains(string, {substringsA} as list) insert {substringsB} else insert original string

I have a table Projects with a column called [Company Name].

I have another table #"Replacement Names" with two columns, [If Company Name Exists] and [New Company Name] (see below)

I want to create a new column in Projects table, and, for each record in [Company Name], I want power query to loop through [If Company Name Contains]. If the record contains that substring, I want power query to insert the string from #"Replacement Names"[New Company Name] in the new column. If it does not contain any of the strings in [If Company Name Contains], I want it to insert the string from [Company Name].

 

I created a conditional column to do this (M code below), and it works, but I think it would be more manageable to do it the way I've outlined above.

 

Any help is appreciated.

Thanks!

Hi @eliPR ,

 

It is more convenient to use the Merge operation to complete.

 

My sample data.

1.Do the Merge operation in the Projects table.

2.Expand the [New Company Name] column.

3.Add a conditional column named Replaced Name.

A merge works well if you have an exact match but I think @eliPR was only expecting your [If Company Name Exists] to be a substring of [Company Name] rather than a column you can join on.

Try this as a custom column:

(row) =>
List.Max(
    Table.SelectRows(
         #"Replacement Names",
         each Text.Contains(row[Contractor Clustered], [If Company Name Contains])
    )[New Company Name]
)
