# Kimi Sheets: controlled local recalculation follow-up
25 September 2026. China AI Chat Team. https://chinaai.chat/kimi/sheets/

The original workbook was generated by Kimi Sheets on 23 September 2026 using a Moderato account with visible K3 High label, one fictional eight-order prompt. The original is included unchanged. No new Kimi request or API call was made for this follow-up.

ENGINE AND METHOD
OpenAI Artifact Tool spreadsheet calculation engine in bundled runtime 26.923.10815. Every case imports the unchanged original separately. Expectations were fixed before edits and derived independently using decimal arithmetic. Baseline was recalculated in memory. Three edited copies were recalculated, exported and independently inspected using ZIP/XML, including formula strings, saved results, source inputs and table ranges. These are local researcher-generated test copies, not new Kimi exports or polished replacement templates.

EXACT EDITS AND RESULTS
Baseline: no edits; line totals37.50,18,14,0,0,33.25,22.50,15. Product subtotals60,33,47.25; grand140.25.
Quantity: C4=4. G4=50, J4=72.50, J5=33, J6=47.25, J7=152.75. All match independently expected values; unrelated inputs/results preserved.
Cancelled: F5=Cancelled. G5=0, J4=60, J5=15, J6=47.25, J7=122.25. All match independently expected values; unrelated inputs/results preserved.
Appended order: copied A11:G11 to A12:G12 then overwrote A12:F12 with WB-109,Pen set,2,5,0,Completed and set G12 to =IF(OR($F12="Cancelled",$C12=0),0,ROUND($C12*$D12*(1-$E12),2)). G12=10. Original summary formulas left unchanged, so J5 stays33 and J7 stays140.25. All-nine business totals would be Pen43 and grand150.25; exactly10 omitted. This is valid arithmetic over an incomplete range, not a formula-error cell. Native table and AutoFilter remain A3:G11. This is direct writing below the table, not testing Excel Insert Table Row or automatic table expansion. No range repair was performed. The original brief requested eight orders, not automatic extension.

FORMULAS
Original G4:G11 use row-relative IF/OR/ROUND. J4:J6 use =SUMIF($B$4:$B$11,$I4,$G$4:$G$11), adjusting I4 to I5/I6. J7 =SUM($J$4:$J$6). All12 original formulas retained in all3 derivatives; appended copy adds G12 only. Exported values match recorded engine values. No formula errors or external relationships were found; ZIP integrity checks pass.

LIMITATIONS
Not a native Microsoft Excel/LibreOffice/Google Sheets UI test. No desktop edit-save-reopen, automatic table expansion, large workbook, new product category or cross-sheet behavior established. Import/export rewrites package metadata/styles. Existing inspected formats and dimensions remained, but the attempted row-style copy did not preserve row12 currency/percentage formatting/alignment/height. This local-tool outcome is not a defect observed in Kimi's original eight-row file. Appended render deliberately shows General-format5/10/0.
The process wrote all four snapshots and previews and all three exports but returned exit code1 with no additional diagnostic. Independent package inspection supports the bounded results above; no claim of a clean process exit. Cause not established. Baseline was not separately exported. No invented cached values, silent repairs or reruns to improve findings.
