There aren't many reasons to create a freeform spreadsheet editor to compete with Excel or gsheet as standalone applications. The two areas where it makes sense to compete are: a) Embedding a spreadsheet like (to varying levels of featurefullness) interfaces into other applications or workflows. A minimal feature set probably doesn't even involve formulas, just the UI affordances of a typical spreadsheet (ie it needs to copy and paste like a spreadsheet). b) You are building something that acts like ms access (or airtable), just aiming for different blends of functionality/freeformness/end user fiddliness.
