Spreadsheets for small online sellers and planners. Seller Sheets Lab makes simple, formula-driven spreadsheet templates for Etsy SEO and rank tracking, 2027 budgeting, and seller bookkeeping with tax estimates – .xlsx files with no macros. Works in spreadsheet apps that open .xlsx files; each listing says where the file was tested. Some formatting may vary. Every file is checked by recalculation before release, comes with a Start Here tab (most files also include sample data), and has no macros or subscriptions. Questions or a formula that doesn't fit? Message the shop and we'll help. Not affiliated with Etsy, Inc.
