For event organizers and marketing operations teams, attendee data usually arrives as deeply nested JSON that is unusable in a CRM without hours of manual reformatting. Automating that transformation into clean, structured Excel output removes a bottleneck that otherwise delays post-event follow-up and lead routing. Because the pipeline handles the nested structure and field mapping consistently, teams can trust the CRM import at any attendee volume, turning a manual export chore into a repeatable step in the workflow.
Data & Analytics
Conference Attendee ETL
Engineered a Python pipeline to flatten complex nested JSON attendee data into structured, CRM-ready Excel reports.

How It Works
A closer look at the workflow behind the results.
1
Nested JSON Ingestion
Raw, deeply nested JSON attendee data is pulled in from the conference platform ahead of processing.
2
Data Normalization & Mapping
Python and Pandas flatten the nested structures across multiple object layers and map fields to a consistent schema.
3
CRM-Ready Excel Export
The flattened data is exported as a clean Excel report with consistent columns, ready to import straight into the CRM.
Metrics
