What is your first impression of the blocking keys and ruleset definitions required for Find Duplicates?

We have observed that it may take a bit of learning to understand the syntax and structure to correctly update the keys and rules.

Here are a few tips and tricks to help ease your experience with reading and updating the keys and rules:

  • Click and drag the corner of the text box to expand ruleset and blocking keys at the Find Duplicates Settings.


  • Use a JSON editor for editing blocking keys.
    • Example: https://jsonformatter.org/json-editor Note: This is not produced or endorsed by Experian. It is a publicly available tool that you may find useful.
    • Paste your blocking keys on the left, populate it to the right where you can change the structure to a Tree structure. Edit on the right where it is more readable, and populate it back to the left to save your changes. You can also validate your syntax (click on the tick sign). When you are happy with it, copy and paste the edited blocking keys back to Data Studio Find Duplicates settings.


  • Use the Notepad ++ plugin for editing rulesets. If you're using Notepad++ as your text editor, this will help you highlight keywords within the Find Duplicates rules and provide auto completion suggestions.


We do have a long term vision to make blocking keys and rules creation more user-friendly. We welcome any ideas from you.
