Column to show string groupings
- 1 year ago
Hi MichaelHutchens ,
Create a copy of the table by duplicating the table in Power query.
Perform Fuzzy Merge - Self-Join
- Go to Files table.
- Home > Merge Queries > Merge Queries as New
- Primary table: Table
- Secondary table: Duplicated Table
- Join on File Name using Fuzzy Matching:
- Check Use fuzzy matching
- Click Fuzzy matching options:
- Similarity threshold = tweak as needed
- check ignore case
- Max matches: blank
In the merged table, remove duplicates so each pair appears only once by using Table.Distinct
Create a group ID table using DAX to assign a group ID to every file participating in a fuzzy match. You can then join it back to your original file list, and if any file name is not present in the Grouping table, assign that group to 0.

Hi MichaelHutchens - DAX does not support fuzzy matching natively, and more importantly, it cannot create calculated columns based on similarity clustering across rows.
suggest, You must use Power Query (M) or external processing (e.g., Python or R script in Power BI) for fuzzy clustering

Thanks for that rajendraongole1 , very useful. I've amended my original post to remove the DAX requirement. I'll take what solutions I can get.
