Frequently Asked Questions
How does it detect missing elements?
The tool compares both arrays element by element and reports any elements that appear in one array but not the other, along with their positions.
Can I ignore the order of array elements?
Yes, use the "Ignore array order" option to compare arrays as multisets, focusing on content rather than position.
Do I need to upload my arrays?
No, all comparison happens locally in your browser. Your data never leaves your device.
