How to Repair Corrupt QuickBooks Company File Data?

QuickBooks company (QBW) file contains data related to company, vendors, customers, and employees.  However, sometimes, the QBW file gets corrupted due to virus attacks, sudden QuickBooks application termination, network issues, etc. In this situation, when you try to access the company file, you may get random errors, such as “QuickBooks cannot open the company file”, “QuickBooks found some issue with your company file,” etc. This can prevent you from accessing the company file data. Therefore, you need to repair qbw file as soon as possible. In this post, we’ll explain different methods to repair damaged/corrupted company files in QuickBooks. 

Effective Methods to Repair and Restore Corrupt QuickBooks Company Files

You can follow the below methods to repair and restore data from corrupt QBW files:

1 – Restore Company File from Backup

If your QuickBooks company file is damaged or corrupted, you can try restoring the backup file (if you have an updated backup file). Here’s how to restore the company file from backup:

  • Open your QuickBooks application.
  • Click the File option and select Open or Restore Company.
  • Click Restore a backup copy and then click Next.
  • Click on the Browse option to search for the backup company file (.QBB).
  • Click on the folder where you want to save the restored file.
  • Click Open. (If you see a message to overwrite your data, click the suitable option.)
  • Once you are prepared, click the Save option. 

However, if it does not work, you can use the QuickBooks Auto Data Recovery (ADR) feature. It is a built-in feature in QuickBooks to recover data from corrupt company file. To use this feature, ensure your company file folder has a transaction log file and .QBW.adr file. Also, your backup file size should be less than 1.5 GB to use the ADR feature. This option is not available in QuickBooks Accountant editions. 

2 – Use QuickBooks Repair Tools

QuickBooks has a Verify and Rebuild Data tool that verifies and rebuilds the QBW file data. If your company file is corrupted, you can use this tool to rebuild the file data. If it does not work, you can use QuickBooks Tool Hub’s utilities. The QuickBooks Tool Hub contains many QuickBooks repair tools, such as QuickBooks File Doctor and QuickBooks Fix My File. Follow the steps below:
