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 ,

 

Table.ColumnNames(#"Filtered Rows") returns a list contains all column names, not the value of the columns. So these parts won't work:

Text.Contains(Table.ColumnNames(#"Filtered Rows"),")"),

Text.Replace(Table.ColumnNames(#"Filtered Rows"),")","")

 

Just add one Index column and use UnPivot and Pivot, then what you want appears:
