List Comparison Made Simple
Whether you're comparing user lists, feature flags, or any collection of items, this tool shows you exactly what changed. You can toggle between order-sensitive mode (where position matters) and set-based comparison (where only presence matters).
Input Formats
- JSON arrays:
["apple", "banana", "cherry"] - Line-separated lists (one item per line)
- Comma-separated values
Comparison Modes
Order Sensitive: Treats the lists as sequences. Moving an item counts as a change.
Order Insensitive: Treats the lists as sets. Only presence or absence matters.
