Replace values in all columns with a formula (Cleaning negative values denoted by brackets)

A table imported from PDF has negative values denoted with one right bracket, like this "6,964.68)". (The left bracket has been placed in a separate column due to the way Power Bi does text to table translation.)

 

I'm trying to replace all values containing ")" with a cleaned and negative version of the value. (ie. "6,964.68)" would become "-6,964.68".

 

Importantly, because this is for a large data set, I'm trying to achieve this:

A: Without creating a helper column and

B. Without referring to specific column names

 

This code works:
= Table.ReplaceValue(#"Filtered Rows",
each [Column9],
each if Text.Contains([Column9],")")
then "-" & Text.Replace([Column9],")","")
else [Column9],
Replacer.ReplaceText,
Table.ColumnNames(#"Filtered Rows"))


This doesn't:
= Table.ReplaceValue(#"Filtered Rows",
each Table.ColumnNames(#"Filtered Rows"),
each if Text.Contains(Table.ColumnNames(#"Filtered Rows"),")")
then "-" & Text.Replace(Table.ColumnNames(#"Filtered Rows"),")","")
else Table.ColumnNames(#"Filtered Rows"),
Replacer.ReplaceText,
Table.ColumnNames(#"Filtered Rows"))

Hi, @powerqueryquest 

 

You can try to use Split in Power query.

The separated blank columns are deleted directly.

Convert the format to Text first. add custom columns.

Then convert the format to digital format.
