About Sheet Reserve
A small, carefully kept library of spreadsheets: templates that show their working and public data that names its sources.
Why it exists
Most template sites sell pictures of spreadsheets: screenshots, locked files, values pasted where formulas should be. Sheet Reserve goes the other way. Every template keeps its inputs, calculations and results visible, names the method it uses on a notes tab, and ships with example data you can replace. Every dataset is pulled from a named public source, kept in its original units and documented column by column.
How files are made
Each workbook is stored once, compressed, in a SQLite database. When you download, your browser writes the format you choose (XLSX, ODS, CSV, XML or Numbers) from that single copy. That keeps the server small and fast and means formats never drift apart.
Who makes it
Sheet Reserve is designed and developed by Yunus Emre Vurgun, a developer based in Istanbul. New sheets are added from the command line and published with the rest of the site; there is no admin panel.
The articles and question pages are drafted with AI assistance, then checked, corrected and published by the developer. Worked examples are recalculated before publication.
