The transition to Canvas has made it much harder to import grades from external tools (like PrairieLearn, Lon Capa, etc). Specifically, to import grades into Canvas, a series of six columns must be present for each row. This client-side tool creates a CSV file ready to be imported into Canvas by matching a single identifier from an external tool to your Canvas gradebook.
As a client-side tool, no data in this tool is ever sent over the Internet. Read the FAQ here.
