Specify the location of the scripts folder you want to compare on the Project Configuration dialog box:

Specify the two sources you want to compare on the Data Sources tab. You specify a source and a target. In the example above the source is the scripts folder that will not change; the target is the database that will change.

To compare Database and Script Folder without having a schema tick checkbox "Take a schema from the source" to use Source schema.

Upgrading from CSV to JSON data format 

In Data Compare V5 and earlier, data was stored in a CSV-like file format. From V6 onwards a new JSON-based format is the default for new files. If you are experiencing issues with the old CSV-like format, you can upgrade your files to JSON.

1. Simply download this CsvToJsonMigration PowerShell module
   CsvToJsonMigration.psm1

2. Import the module

   Import-Module $ModuleDownloadLocation

3. Use the Convert-CsvToJson function

   # Convert a CSV-based scripts folder in the directory C:\Users\ABC\MyScripts
   # to the JSON-based format and create a backup copy of the original scripts
   # folder that will be placed in the directory C:\Users\ABC
   Convert-CsvToJson C:\Users\ABC\MyScripts
   
   # Convert a CSV-based scripts folder in the directory C:\Users\ABC\MyScripts
   # to the JSON-based format and do not create a backup copy of the original
   # scripts folder
   Convert-CsvToJson C:\Users\ABC\MyScripts -NoBackup
