Use it as a working system
- Replace example rows with your own planning data.
- Keep categories and naming consistent so summaries remain useful.
- Use XLSX/CSV/PDF exports when the workflow benefits from continued editing or sharing.

How OpenFileTools processes it
Local processing, explicit choices.
The browser stores working data in local component state, calculates summaries on-device, and creates requested downloads locally. OpenFileTools does not receive the working dataset.
Questions, answered.
Is my data uploaded?
No. Batch 4 planners, decision systems, SEO workbenches and local media composition tools process their working data in this browser tab.
Does this use live external data?
No. Unless a future tool explicitly says otherwise, Batch 4 uses only the values and files you provide.
