How to update on mass sales account profile org type

Summary:

I would like to be able to extract all organizations where the org type on the account profile is x and update to y on mass.

Content (please ensure you mask any confidential information):

I can't seem to find the table which holds the org type or the lookup. Tried looking in apps composer all it says is 'PrimaryOrgTypeMeaning'. If I could extract the right id's and knew the attribute to update I could potentially use Import Management to do the update.
