# Bulk Update on Attendee Fields

We fully understand the importance of efficiently managing attendee information. To simplify this process, we are excited to introduce a new feature that allows event organizers to update attendee information in bulk using CSV templates. This feature will save you time and effort by enabling you to make changes to attendee details offline and then seamlessly upload the revised file to our platform.

* **Time-Saving**: **Updating attendee information individually can be time-consuming**, especially for events with a large number of attendees. With the bulk CSV upload feature, you can make updates to multiple attendee records simultaneously, significantly reducing the time and effort required.
* **Error Prevention**: Organizers can upload the same file as the previous import. Not needing to download any new templates.
* **Seamless Integration**: **The feature supports all types of attendee fields**, and various types of fields, including Single Choice, Multiple Choice, and Dropdown. When updating choice type fields, the existing options will be mapped automatically, ensuring consistency and accuracy in attendee information.

To update attendee information using the bulk CSV upload feature, follow these steps:

1. On the **People List**, click **More >>>** **Import CSV**
