jq -r '.cells | to_entries[] | "\(.key): [\(.value.cell_type)] id=\(.value.id // "none") | \(.value.source[:1] | .[0] // "" | .[0:80])"' NOTEBOOK.ipynb

Replace a Cell's Source

# Replace cell by index (0-based)
jq --arg src "print(\"hello world\")\n" \
   '.cells[0].source = ($src | split("\n") | map(if . == "" then . else . + "\n" end) | .[:-1])' \
