I have found credit note error in json file

Hi @sapna1,

Thank you for posting here in the Community. I can help you get rid of the credit note error in the JSON file.

In QuickBooks Online, there are different types of error messages related to a credit note when exporting a JSON file. I will share the steps below for the two most common problems and how to fix them.

If the credit note number is missing in Section: 9B(Unregistered):

1. Click Reports from the left navigation bar.
2. In the Go to report search box, type GSTR1 and select GSTR1 - Summary Of Outward Supplies and run this report for the same period.
3. Click into Section 9B. Credit/Debit Notes (Unregistered)
4. Locate credit notes that have a blank entry in the Credit Note No. column.
5. Edit these credit notes and update them with a transaction number each.

In case you get an error that the credit note number is too long in Section: 9B(Unregistered):

1. Click Reports from the left navigation bar.
2. In the Go to report search box, type Transaction List By Customer and run this report for the same period as the GSTR1.
3. Locate Credit Notes which have more than 16 characters in the No. column.
4. Click to open the transaction, truncate or enter a new Credit Note no.  and select Save and close.
