Overview
Sheet Reserve is a library of spreadsheet templates and public datasets. It lists 158 sheets covering finance, accounting, budgeting, engineering, industrial engineering, architecture, bidding, chemistry and management, each built with working formulas and fictional example data that can be replaced. Alongside the templates it publishes public datasets, such as GDP, inflation, trade, climate and water indicators, with their sources, licences and citations named.
Every sheet has a public preview and documentation covering its tabs, method, inputs and limitations. Downloads are written in the browser in five formats: XLSX, ODS and XML keep formulas, while CSV and Numbers exports contain values only. A yearly membership costs US$19.85 and covers the whole library, including sheets added during the year, for personal and commercial use. Two sample sheets, a household budget and a world geography dataset, download with a verified free account, and the browser-based CSV tools need no account. Payments are handled by Gumroad as merchant of record, and the membership renews automatically until cancelled.
