Heap sort animated: build the max-heap, swap the root to the end, sift down — every comparison colored TRUE/FALSE with live pseudocode.
Tip: use samples, upload, copy, download, and send-to actions inside the workspace where available.
Heap Sort Visualizer is a free, browser-based tool that helps you convert between formats. Heap sort animated: build the max-heap, swap the root to the end, sift down — every comparison colored TRUE/FALSE with live pseudocode. It's built for speed and privacy: Everything runs locally in your browser — your data is never uploaded to a server. No sign-up, no installs, and no daily limits.
Start with the source file or pasted payload, then confirm delimiters, headers, and field handling before conversion.
Review the preview, copy or download the result, and keep everything local in your browser.
Binary Search Tree Visualizer: Insert, delete, search, and traverse a BST, AVL tree (animated rotations with balance factors), or min-heap — every comparison narrated, every pointer move animated.
Open toolMerge Sort Visualizer: Merge sort animated: runs split, then merge back as the smaller head wins each comparison — with lo/mid/hi pointers, counters, and pseudocode.
Open toolSorting Algorithm Visualizer: Watch bubble, selection, insertion, merge, quick, and heap sort run step by step — animated bars, comparison and write counters, plain-English narration, and complexity cards.

Builds a max-heap, then repeatedly swaps the root (maximum) to the end and sifts the new root down. Guaranteed n log n, in place.
