EDISIM and EDI data sanitization

Hi
We need to sanitize large EDI data.
The current production EDI data has sensitive information which should not be used as test-data during Integration Testing.

Manually we cannot replace customer sensitive information by hardcoding to different values.

Question–

  1. How do I generate test data for varied EDI standards like 810,214,832 in the range of 50 MB?

  2. I heard EDISIM can help me solve this issue. Has anyone used EDISIM. If so please help me.

Thanks and Regard
Srinath
