Batch Renamer by Nesbit Labs

Batch rename Unity assets without risking broken names or blind changes

Nesbit Labs Batch Renamer is a focused, editor-only tool built for safely renaming large groups of assets with full visibility and control.

Every change is previewed before you apply it, conflicts are clearly flagged, and you can roll back the most recent batch if needed.

Whether you're cleaning up a messy project or standardizing naming across a production folder, this tool helps you move fast without losing confidence in the outcome.

Controlled, preview-driven workflow

Rename assets using simple add or replace rules, or apply formatted names with indexed numbering.

Generate a full preview of all changes, filter results by file type, and review or exclude individual items before applying.

Conflicts are detected up front, with options to auto-fix or skip problematic entries. If something needs to be reversed, the most recent batch can be restored using the built-in rollback system.

Built for clarity and control inside Unity

Designed for developers and artists who want a clean, predictable workflow inside the Unity Editor, without relying on risky or opaque batch operations.
