We're providing a tool that can be used to look into issues with a plaintext JSON/OData file. It supports VICS formats through version 1.2.
1. Download the attached zip file (updated Jan 26, 2016)
2. Unarchive it to a temporary directory
3. Open a command prompt and navigate to the temporary directory
4. Run the command GetJsonStats.exe with the file name as the first argument. For example, GetJsonStats.exe c:\temp\myfile.json
If the file fails to parse, the tool will provide the last line that parsed successfully. If the processing completes without error, the tool will show a representation of the number of items in each category as well as other useful statistics.
