Data standardization means making data values consistent across all sources.
We converted different formats into a common business format.
In my project, “TN”, “Tamil Nadu”, and “T.Nadu” were standardized to one value.
Date formats like DD/MM/YYYY and MM-DD-YYYY were unified.
Currency values were converted into single currency for reporting.
Product names from multiple systems were mapped to master product list.
Text casing and extra spaces were cleaned for uniformity.
This improved joins and aggregation accuracy in the model.
Users avoided confusion seeing same category in different names.
So standardization ensures consistent and reliable reporting outputs.
