On the topic of tools, I vaguely recall mention of there being some integration with Excel. If I’m remembering correctly:
How does it work? Does the engine read the .xls file or is it via OLE? Can we access the imported data via blueprints? Any thoughts on supporting other formats, such as OpenOffice/LibreOffice/Google Docs (via Google App Script formatting the data into json or whatever), or even just .csv, json, relational databases, xml, or whatever other formats people store data with?
