About the Project

The Problem

Empty cells during Supabase CSV imports were treated inconsistently, admins couldn't control whether they became NULL or empty strings, causing confusion across large dataset workflows.

Collaboration

Worked with Charis Lam and Deni Mintsaev (issue #43258) to identify a better UX for nullable imports after reviewing PR #43281.

The Solution

Implemented PR #44515, a multi-select dropdown letting admins choose which columns treat empty CSV cells as NULL.

Selected columns → empty cells become NULL
Unselected columns → empty cells remain ""

Impact

Cleaner import clarity
Better admin control
Improved database consistency
More predictable workflows
