Anybody know of a decent process embeddable spreadsheet engine, not web embedded in website embedding, but linked in process.

Ideally C++. I ended up taking sc-im codebase and wrestling with it to embed it in a system. Old school I know but it works.

Would Excel interop work? It's not in the same process and horribly inefficient but will always result in Excel compatible spreadsheets.

I’m interested in higher performance and don’t really care about file or data output. I can also deal with the UI issues.

Basically it’s the core calculation and formula engine I was hoping was implemented as a library that could be plugged into another application.

Okay, in that case not a good option.

Good luck, that sounds like a very useful tool you're building.

Python’s pandas. Or Apache Arrow (more data structure, but with some calc capabilities). Granted, they’re not spreadsheets per se. Rather, they’re dataframe-centric programming.

Not really what I mean. Spreadsheet implements a generic formula evaluation engine that triggers updates on value changes efficiently.

if you need only an engine which does formula evaluation and update of dependency when a value changes, it doesn't look that hard to implement.
