"Need help on how to replace an example set with descriptions using Replace (Dictionary)"

Need help on how to replace an example set with descriptions using Replace (Dictionary).The example set has attributes with alphanumeric codes. I have an excel spreadsheet (csv format) that has descriptions of the alphanumeric codes(e.g. A11, A12, A13, etc.) that I want to replace. What step by step approach can be used to replace all the alphanumeric codes with descriptions from excel table automatically. I am working on replicating the example on chapter 4, pg. 78 of Predictive analytics and data mining textbook but got stuck on replacing the alphanumeric codes in the example set with the descriptive values in excel. I appreciate any help. Thanks

HI @Dataprep101,

The attributes names in your dictionnary and the attribute names you set in the Replace (Dictionnary) operator parameters must be the same :



Hope it helps,
