Your Item list is setup with inches (2" X 4" X 10') and when the Item list is exported and then imported into a new company file the inch mark (") is changed to the foot mark (').
Edit the .iif file in Microsoft Excel and change the foot marks (') that should be inch marks to two individual foot marks (''). Then reimport the .iif file.
Note: If you change it to the inch mark (") it will not import correctly.
Export your list to an IIF file.
Edit the file in Microsoft Excel to change the foot mark (') to two foot marks ('') so it will import as inch marks into the new company file.
Import an IIF file into your QuickBooks Desktop file
