Quick Answer
How do I simulate a corrupted CSV for tests?
Use Byte Flip or Block Noise in Hexwilt to scramble CSV delimiters and rows, then feed the output into your parser tests.
Load CSV
Pick Byte Flip or Block Noise
Download + attach report
Open the CSV in Hexwilt. Because processing is local, even sensitive datasets stay on your machine.
Choose Byte Flip to disturb delimiters or Block Noise to blank entire row ranges. Set intensity based on how catastrophic you want the failure to be.
Download the corrupted CSV and include the corruption report in your regression suite so you can replay the scenario anytime.
