Power BI - Power Query Editor

Consider this Power Query M code intended to replace "TX" with "Texas" in the "Region" column:

Table.ReplaceValue(Source, "TX", "Texas", Replacer.ReplaceText, "Region")

Why does this code produce an error?

ABecause the column name must be provided as a list, e.g., {"Region"}

BBecause Replacer.ReplaceText cannot be used for text replacements

CBecause the old value "TX" is case sensitive and does not match

DBecause the function requires an additional parameter for data type

Step-by-Step Solution

Solution:

Step 1: Identify the error cause
The error arises because the column parameter is passed as a string instead of a list.
Step 2: Correct usage
The column argument must be a list of column names, e.g., {"Region"}.
Final Answer:
Because the column name must be provided as a list, e.g., {"Region"} -> Option A
Quick Check:
Column names must be in a list [OK]

Quick Trick: Column names always need braces in ReplaceValue [OK]
