About the editorial desk
Focused workbooks for real factory routines
Factory Sheets publishes free, direct-download Excel workbooks for bounded manufacturing planning, materials, operations, quality, maintenance, and performance workflows.
What we publish
One page, one workflow, one working file
Each resource identifies the fields a user enters, the calculations or controls in the workbook, the outputs it returns, and the point where the file’s scope ends. The goal is a practical starting point that can be checked and adapted—not a generic business system.

Editorial limits
Useful without overstating the file
Ground the page in the workbook
Descriptions follow the sheets, fields, formulas, validation, and instructions in the released XLSX.
State what was checked
Public credits and compatibility wording appear only when their resource-specific evidence is complete.
Leave specialist decisions to specialists
We do not present a workbook as compliance proof, professional advice, an official form, or a certified system.
