Instant Comparison

Upload two CSV files and automatically detect all differences – no manual comparison needed.

⚙️

Check System Configs

Compare settings from test and production systems to ensure both are identically configured.

📊

Track Changes

After adjustments in a system, immediately see which fields have changed – and fix them specifically.

Use Case: Customising control before integration testing

Before an integration test, system settings in test and production must be identical. A consultant exports the configuration tables from both systems as CSV files and uploads them to the CSV comparison tool.

The tool automatically checks all fields and highlights differences directly in the interface. The consultant immediately sees which settings differ – without manually comparing line by line.

After a change in one of the systems, the comparison can be run again. The direct output of all fields and automatic checking enables verification in seconds. Particularly effective when customising must be checked before an integration test.
