Write a script :-) p.bodyString() is the body text of node p, so what you want is a script that will update your spreadsheet nodes. Something like: for p in c.allNodes_iter(): if spreadSheetEval(p): myEval(p) You define isSpreadSheetNode and spreadSheetEval. This does a global re-evaluation, but it's a start. To refine this, you can re-evaluate the neighbors of changed nodes. To determine when a node changes, you can create an event handler for one of the 'select' events. HTH.
