Good evening, @djren22.
Congrats on making your first post here in the Community. Let me share some insight into exporting your General Ledger to Excel.
Based on the details you shared, this sounds like you need to edit your settings within Excel so that you're able to bring over more than 50,000 rows from QuickBooks Desktop.
If you're unsure of where the settings are located, I recommend contacting their support team so you can get this fixed as soon as possible.
We're always here to lend a helping hand, so if you need more assistance, don't hesitate to ask. Have a great day!
