How to create M function to Find and Replace the Value?

[Dhruvin]

I know, Power BI provide Replace fiunction Out Of the Box.

Still, I want to create a Custom Function (M function) which will read value from the dataset for find and Replace with a word. 

How to create this function and call the function on a specific column of a table.

Example: 

I have County column in a database. For County I want to create a function which will read the Find value from another dataset and replace found word with another column named "Replaced value".

How to achieve this requirement?

Hi,

If you are willing to use another column, you can simply join the two tables.

Hi @Dhruvin

Let me confirm the requirement with you

find the value "a" in "country" column in table1, then replace the "a" with another value from another table.

If my understanding is correct, here is a thread you could refer to
