Dynamic Multi-Condition Revenue Filter (QUERY + IMPORTRANGE)

Pulls paid customer transactions from another sheet or tab, filters exclusively by date ranges and minimum purchase value, and sorts descending by amount.

=QUERY(
  IMPORTRANGE("https://docs.google.com/spreadsheets/d/YOUR_SHEET_ID_HERE", "Orders!A:F"),
  "SELECT Col1, Col2, Col4, Col6 
   WHERE Col4 = 'Completed' 
     AND Col6 >= 25 
     AND Col1 >= date '"&TEXT(TODAY()-30, "yyyy-mm-dd")&"' 
   ORDER BY Col6 DESC 
   LABEL Col1 'Order Date', Col2 'Customer Name', Col4 'Status', Col6 'Revenue ($)'",
  1
)
💡Implementation Tip: Replace YOUR_SHEET_ID_HERE with the URL ID of your master transaction spreadsheet. Grant access once when prompted by Google Sheets.

Automated Low-Stock Reorder Alert (IFS + XLOOKUP)

Calculates whether an inventory SKU requires immediate reordering based on current warehouse quantity, daily sales velocity, and supplier lead days.

=IFS(
  B2 <= 0, 
  "🚨 CRITICAL: Out of Stock",
  B2 <= (C2 * D2), 
  "⚠️ REORDER NOW (" & ((C2 * D2 * 2) - B2) & " units needed)",
  B2 <= (C2 * D2 * 1.5), 
  "⚡ Low Buffer (" & ROUND(B2/C2, 0) & " days remaining)",
  TRUE, 
  "✅ Healthy Stock (" & ROUND(B2/C2, 0) & " days)"
)
💡Implementation Tip: Assumes Cell B2 = Current Stock, Cell C2 = Average Daily Sales, and Cell D2 = Supplier Lead Time in Days. Drag down across all catalog SKUs.

Marketplace Gross Margin & Net Payout Calculator (LET + LAMBDA)

Modular formula that dynamically deducts payment gateway percentage, flat transaction fee, packaging costs, and ad spend to reveal true net profit per order.

=LET(
  salePrice, A2,
  costOfGoods, B2,
  adSpendPerUnit, C2,
  gatewayRate, 0.029,
  gatewayFlat, 0.30,
  marketplaceFeeRate, 0.05,
  grossRevenue, salePrice,
  gatewayFee, (grossRevenue * gatewayRate) + gatewayFlat,
  platformCommission, grossRevenue * marketplaceFeeRate,
  totalDeductions, costOfGoods + adSpendPerUnit + gatewayFee + platformCommission,
  netProfit, grossRevenue - totalDeductions,
  netMargin, netProfit / grossRevenue,
  "Net Profit: $" & TEXT(netProfit, "0.00") & " (" & TEXT(netMargin, "0.0%") & " Margin)"
)
💡Implementation Tip: Input Sale Price in A2, COGS in B2, and Ad Spend per Unit in C2. Works natively in modern Excel and Google Sheets without external add-ons.

Smart Lead Phone & Country Code Standardizer (REGEXREPLACE)

Cleans messy, human-entered phone numbers containing brackets, hyphens, and spaces into a clean international WhatsApp and CRM-ready format.

=IF(ISBLANK(A2), "", 
  LET(
    rawDigits, REGEXREPLACE(TO_TEXT(A2), "[^0-9]", ""),
    IF(LEFT(rawDigits, 1) = "0", 
      "+62" & MID(rawDigits, 2, 20),
      IF(LEFT(rawDigits, 1) = "8",
        "+62" & rawDigits,
        "+" & rawDigits
      )
    )
  )
)
💡Implementation Tip: Cell A2 contains the raw phone input (e.g. "0812-3456-7890" or "(0812) 34567890"). Adjust the "+62" prefix if your target country is outside Indonesia.

Rolling Monthly Customer Retention & Churn Rate (SUMIFS)

Computes active subscriber retention percentage for any given billing cycle against the original cohort signup count.

=LET(
  cohortSignups, COUNTIFS(Subscriptions!$B:$B, B$1, Subscriptions!$C:$C, "<="&EOMONTH($A2, -1)),
  retainedActive, COUNTIFS(Subscriptions!$B:$B, B$1, Subscriptions!$D:$D, ">="&$A2, Subscriptions!$C:$C, "<="&$A2),
  IF(cohortSignups = 0, "-", TEXT(retainedActive / cohortSignups, "0.0%"))
)
💡Implementation Tip: Row 1 contains Cohort Months, Column A contains Rolling Reporting Months. Table dynamically outputs retention curve percentages.

How to Install & Configure These Vault Assets

Zero technical friction. Select your asset category below for practical, bulletproof deployment steps in under 2 minutes.

01

Cell Placement & Formula Bar

Always select the exact destination cell in your worksheet. Rather than double-clicking directly on the cell, paste the formula into the Formula Bar (fx) at the top of the spreadsheet. This prevents Google Sheets or Excel from auto-escaping double quotes and breaking nested string expressions.

02

Resolving Regional Delimiters (Comma vs Semicolon)

If the spreadsheet displays a #ERROR! or Formula parse error immediately upon pasting, your Google Sheet or Excel regional setting uses European/Indonesian delimiter notation. Check File > Settings > Calculation / Locale. If your locale uses semicolons, simply replace comma delimiters (, ) with semicolons (; ).

03

Authorizing Cross-Workbook Connections (#REF!)

When using IMPORTRANGE to pull data from a secondary workbook, Google Sheets will initially show a #REF! error. Hover your cursor directly over the cell and click the blue "Allow access" button. Once clicked, the authorization token persists permanently across team collaborators.

04

Freezing Calculated Arrays to Prevent Recalculation Lag

For massive datasets (>5,000 rows) or closed financial month-end reports, copy the dynamic formula results with Ctrl+C (or Cmd+C) and press Ctrl+Shift+V (or Cmd+Shift+V) to Paste as Values. This preserves the static numbers while freeing up spreadsheet memory.

🤖 AI Provenance & Quality Standards

Every formula, system prompt, and script presented in this repository is drafted using state-of-the-art AI models (Claude 3.5 Sonnet, GPT-4o, and Gemini Flash) and audited against live production constraints. We enforce strict anti-slop guidelines: no fabricated Excel functions, no non-terminating loops, and no hallucinated API endpoints.

⚖️ Fair Use & Commercial License

All assets in this vault are released under open Fair Use (MIT-equivalent). You are completely free to copy, adapt, modify, and integrate these formulas and prompts into your internal company spreadsheets, client deliverables, e-commerce workflows, and commercial software without paying royalties or linking back.

📈 Zero Gatekeeping for Non-Coders

Unlike conventional programming portals that require Docker, Git, or complex compilers, our snippets are designed for immediate copy-paste utility in standard business software: Google Sheets, Microsoft Excel, ChatGPT, Claude, and Google Apps Script.
