CSV File Upload (Static)

You can also create a Cohort by uploading a CSV file. Cohorts created through direct file upload are classified as the Static type. A Static Cohort is a static — that is, fixed — list of user identifiers.

Category
Description

File Size

Up to 128MB

File Format

CSV

Number of IDs

Up to 1,000,000

Each row is treated as one entry. If there are duplicate entries in the file, they are counted as one entry.

Check the example below for a file suitable for Static Cohort upload.

List the identifiers you want to upload without column separators.

Creating a Cohort by Uploading a File

1. Visit the Cohort Page

Go to the Cohort page and click the File Upload button.

2. Select a CSV File

In the modal that appears after clicking the button, you can upload a file by selecting it directly or dragging and dropping it.

3. Upload and Create

3-1. Fill in the required information and click the Create button.

3-2. Wait for the Cohort upload to complete.

The CSV upload process may take up to 5 minutes.

If you leave the page during this process, the Static Cohort upload may fail.

Re-uploading a Static Cohort

You cannot directly modify a Static Cohort after it has been created.

Instead, you can re-upload the file for an already-created Static Cohort.

Cohort Detail Screen

Click the Re-upload File button on the detail screen of the created Cohort.

Created Cohort detail screen

If the re-upload is successful, the existing user list is removed and replaced with the newly uploaded user list.

If you need to modify a Cohort that is already in use, it is recommended to re-upload using this method rather than creating a new Cohort.
