QB Issue Resolution:
Let me share a few information about IIF files and how to create and import them in QuickBooks Pro 2018.
Intuit Interchange Format (.IIF) files are ASCII text, TSV (Tab-Separated Value) files that QuickBooks Desktop uses to import or export lists or transactions. This type of file makes it easier to record lists/transactions especially if you have large amount of data to be imported.
You can create an IIF file from scratch. It would be best to seek assistance from an IT professional since this involves formatting delimited text files. For more information, you can check this article: https://community.intuit.com/articles/1501233
You export the Chart of Accounts to Excel and remove/add accounts, then import the Excel file into QuickBooks Desktop. Here’s how to export the COA to Excel:
1. Click the Lists menu.
2. Select Chart of Accounts.
3. Click the Report drop-down menu at the bottom.
4. Select Account Listing.
5. Click the Excel button and follow the on-screen instructions.
After that, you can follow the same steps provided by @MorganB (If you happen to be a QuickBooks Desktop user, here’s how you can import accounts from Excel).
