Value Mapper using String
Can I use value mapper using string data? I want to label social media posts based on the caption to specify what products are they talking about.
For instance
So I want to search for "ball" in the caption and put "ball in a new column. Same goes for "food" in the second row.
Any advice is highly appreciated.

Hello @Adhitya,
Value mapper would not be the best thing in this specific example. In Magic ETL the best thing to do is to create a filter for each value and then add constants.
For example
Data -- > (filter column) filter for when `column` contains 'ball' --> (Add constants) Add a column with the text 'Ball'. --> You would then Append all of your data together to get all results the same.
Here are some screenshots of the steps:1

I went the harder way and learned myself a little bit of SQL Dataflow
My solution was using this
SELECT *,
CASE
WHEN `caption` LIKE '%ball%' THEN ‘ball’
WHEN `caption` LIKE '%food %' THEN ‘food’
ELSE ‘ ‘
END as `products`
FROM text
I think yours is easier to learn and implement. Thankyou @ilikenno!
