Nested spreadsheets · local + cloud · format v2

Grids all the way down.

A spreadsheet where every cell can hold another structure — grid, table, list, or dictionary. Drill with Space, climb with Esc, write formulas that walk the tree.

Product

One model, nested structures

Metagrid is not “multiple sheets with VLOOKUPs.” The document is a single tree. Scalars and formulas sit next to nested structures. Field formulas and nested types on tables scale that idea without inventing a second product. Dictionaries are one-record tables with named fields; lists are numbered values.

FeaturesStructures, formulas, keyboard shell, cloud, virtualization — what ships. DocsMental model, navigation, formula language, file format, Agent API, quick start. ArchitectureModule layout, layers, eval path, persistence, dependency invalidation. RevisionWhat we already simplified, what still needs work, and why. AboutWhy this exists and what “done enough” means. AppOpen the spreadsheet. Sample workbook is preloaded.
