About this Tool
The text-compare tool on AllThatConverter compares two versions of code side-by-side, analyzing block modification highlights line-by-line. Because the formatting completes 100% locally inside your browser buffer sandbox, it prevents telemetry leaks, letting you format secret configurations with absolute trust.
