The model lives in a separate spreadsheet nobody links from the doc.
The sheet is a file in the same workspace, beside the document that cites it.

Why sheets choose DotMD
The numbers always end up somewhere else
Three ways data drifts away from the writing — and what keeps it close.
Exported CSVs go stale the moment the source changes.
Cross-sheet references recalculate; there is no export to go stale.
A binary spreadsheet gives you no useful diff in review.
Markdown tables diff line by line like any other text.
Made for the way you work
A spreadsheet that computes
Not a pretty table — an engine.
80 built-in functions
SUM, AVERAGE, IF, VLOOKUP, COUNTIF and the rest, with ranges, nesting and formula autocomplete as you type.
Cross-sheet references
Pull a value or a range from another sheet and let it recalculate. Assumptions in one place, results in another.
Rows, columns and export
Insert, delete, sort and resize, then export to PDF when the number needs to leave the building.
Sheets
Keep the maths next to the argument
Your sheet is a Markdown table with a formula engine over it — reviewable in a pull request, readable in a text editor, yours on the way out.
