# Excel Generator
Create a workbook that is useful immediately on open: accurate, navigable, editable where appropriate, and visually clear. Workbook generation is local and deterministic. SandBase is optional only when the user asks for current external data and no authorized dedicated source is already available.
Read [the SandBase API map](references/sandbase-api-map.md) only when external data retrieval is required.
## Define the workbook contract
Infer reasonable defaults from the request, but resolve missing choices that change the result:
- intended decisions and audience;
- input data, source, freshness, units, and missing-value meaning;
- required sheets, calculations, filters, charts, and editable inputs;
- locale, currency, date system, time zone, and decimal conventions;
