Merge Jupyter notebooks online, combine ipynb files into one .ipynb in your browser
When you need to merge jupyter notebooks online for a class hand-in, a single GitHub artifact, or a client report, this tool stacks multiple .ipynb files in the order you choose and downloads one valid nbformat notebook. It is built for searches like merge jupyter notebooks online, combine ipynb files online, merge ipynb files, and join jupyter notebooks online without installing nbconvert, Pandoc, or a Python environment on the machine in front of you. Each source notebook stays in your tab until you download the merged result, nothing is uploaded for merging.
People look for combine jupyter notebooks and how to merge two jupyter notebooks when lecture notes, exercises, and solutions live in separate files. Drag your files in, move rows up or down to fix story order, then toggle pro-style options: Markdown section headers per source file so reviewers see where each notebook began, keep or strip cell outputs, clear execution counts for a clean hand-off, or renumber In [ ] counts sequentially after the merge so the narrative reads top to bottom. Kernel metadata follows the first file so the merged notebook still opens in JupyterLab or VS Code as expected.
