Here are some errors you may encounter when uploading your student CSV file and how to troubleshoot them.

The CSV file you are attempting to upload doesn't match our requirements.

Make sure your file is a .csv file and includes a header row.

What does this mean?

This means that the file that is being uploaded is not in the correct CSV format. This can occur if the file is not a CSV (Comma delimited) file.

How do we fix it?

The easiest way is to Download Current Students again. This will provide a fresh CSV file in the correct format with the correct columns for the account. When saving the file after making changes it is important to not change the format, it must be saved as a .csv file. **Additionally, if using a Mac, we do not recommend using Numbers when working with a CSV file. Numbers processes CSV files differently and requires extra steps to ensure the file is actually formatted correctly. Instead, if Excel is not available, Google Sheets does allow for files to be imported/exported as a CSV.

First, coordinator should double-check their CSV file to make sure the teacher has 36 students, or less, in each classroom. If teacher will have more than 36 students, they will need an additional license and classroom. If teacher has 36 students or less, the easiest way is for the coordinator to clear the rosters before attempting to upload the current file again. Simply Download Current Roster again, and mark all students with a lowercase "y" in the Deleted column of the CSV. Upload this file to clear the roster. After that, uploading the new file to update the roster should work.

How do we fix it?

Students cannot have changes made and be transferred at the same time. It is recommended to edit students with a separate file as a later step in the rostering process.

Generally, it is best to split rostering into 4 steps and to download current students again before moving to the next step (see Setting Up Student Rosters):

1) Remove students

2) Transfer students

3) Add new students

4) Edit students (if needed)

When transferring students, the only changes to the file should be to the Teacher Username and Classroom Name columns.

No error received but students still have not been removed from teacher rosters.

You have successfully imported students.

What does this mean?

This occurs because students were not correctly marked to be deleted. There are no errors in the file but the Deleted column has an uppercase "Y" instead of a lowercase "y".

How do we fix it?

Replace the uppercase "Y" in the Deleted column with a lowercase "y" and re-upload. This will correctly remove the students from the teacher rosters.
