Compare Data feature of Realfire helps you compare the data across two different Salesforce orgs based on any soql. As you compare, you can copy changes to either source or target connections to fix any differences and Save the data directly to corresponding Salesforce orgs.

Here are some of the notable capabilities of this tool.

• Select any Salesforce org as Source or Target
• Issue same query against selected orgs and brings the data
• You can select one or more fields as compare driving fields (defaults to first soql field)
• Filter the records by various criteria (Same, Differences, Added, Modified etc) to reduce to set of records you are trying to compare
• Make changes (copy from Source to Target or visa versa) and Save from tool
• Export the records into csv with differences
