Audit Cell Suggestions with Whole-Cell Comment Anchors Before Resolving
Review proposed margin formulas in shared cloud workbooks using whole-cell comment anchors, suggester role guardrails, and changed-input stress checks.
Test changed inputs on a suggested formula before resolving its cell comment
On a shared Arte Sheets P&L workbook, giving a reviewer the suggester role lets them propose cell formula edits and post @mention comments anchored to specific cells without directly overwriting live numbers; owners and contributors inspect the formula, test a changed input, and only then accept the suggestion and resolve the comment thread.
Enter Revenue = 25,000 (B2), COGS = 14,000 (B3), and Outbound Freight = 1,500 (B4). A hasty draft in B5 computes Gross Margin % as (B2 - B3) / B2 = 0.4400 (44.0%), omitting Outbound Freight! A reviewer anchors a comment on B5 proposing Landed Contribution Margin (B2 - B3 - B4) / B2 = 0.3800 (38.0%, a -6.00 percentage-point correction). Note that if a Pro owner/editor/suggester inspects the sheet through the Arte Sheets ChatGPT connector 0.1.0 (In review / Not published), read_range (<= 200 cells) returns raw formulas and stable whole-cell anchors for list_comments / add_comment / resolve_comment (<= 25 entries) without recalculating values — so always verify arithmetic in the live sheet!
| Review Step | Spreadsheet / Role Check | Sample Result |
|---|---|---|
| Draft Gross Margin (Omits Freight) | (B2 - B3) / B2 | 0.4400 (Overstates landed margin) |
| Suggested Landed Margin (Anchored B5) | IF(B2 <= 0, "Zero Revenue", (B2 - B3 - B4) / B2) | 0.3800 (-0.0600 correction) |
| Changed-Input Stress Test | Raise Freight B4 from 1,500 to 3,500 | Drops cleanly from 0.3800 to 0.3000 |
| Thread Resolution Gate | Accept suggestion & resolve comment only after check | Prevents premature resolve |
Guarded Landed Contribution Margin % Formula
Guard zero or negative revenue (B2 <= 0) before subtracting both COGS (B3) and Outbound Freight (B4).
=IF(B2 <= 0, "Zero Revenue", ROUND((B2 - B3 - B4) / B2, 4))Margin Overstatement Variance & Comment Sign-Off Gate Formula
Measure the exact gap between the unadjusted draft (E2) and the landed margin suggestion (E3), and require both a valid numeric margin and a verified changed-input flag (B6 = "Verified") before marking the anchored B5 review thread ready to resolve.
=IF(NOT(ISNUMBER(E3)), "Fix Zero-Revenue Guard First", IF(B6 = "Verified", "Ready to Accept & Resolve Anchor", "Test Changed Input Before Resolving"))Try the example
