Hi there, With your current ESdat Online license, it is not possible to import a Chem Profile. The most efficient way to make bulk updates for a Chem Profile would be building a Chem Table with all the parameters you want to customize, and making edits in the Chem Profile section. By clicking the Pause icon to the right of the blue banner, you can disable the display from loading after each edit. Edits can be made to customize Chem Groups, order, output units, and output names. Paige Spurgeon -- ESdat Support
