Want complete control over your deal tracking workflow? Building your own litbuy spreadsheet clone using Google Sheets gives you unlimited customization, private data storage, and the freedom to track exactly the categories, stores, and price thresholds that matter to you. This step-by-step tutorial teaches you to build a functional deal tracker from scratch using free tools and public data sources.
If you prefer using the polished ready-made version instead, grab our official free litbuy spreadsheet and skip the manual build. For advanced strategies, also see our hidden features guide.
Why Build Your Own?
The official litbuy spreadsheet is curated, maintained, and optimized for broad audiences. But power users sometimes want private tracking, custom categories, or integration with personal budgeting tools. Building your own clone delivers three unique advantages: complete data ownership (nothing leaves your Google account), custom alert thresholds (track any product from any store), and integration with personal finance workflows (export directly to your expense tracker).
Step 1: Create the Foundation Sheet
Open Google Sheets and create a new spreadsheet named "My Deal Tracker." In Sheet1 (rename it to "Active Deals"), create the following column headers in row 1:
A: Product Name | B: Store | C: Category | D: Original Price | E: Current Price | F: Discount % | G: Size/Variant | H: URL | I: Price History | J: Alert Threshold | K: Last Checked | L: Status
Format row 1 with bold text and a light background color to distinguish headers. Freeze row 1 so it remains visible while scrolling. Set columns D, E, and F to Currency format (Format → Number → Currency) and column F to Percentage format.
Step 2: Build the Discount Formula
In cell F2, enter the following formula to automatically calculate discount percentage:
=IF(AND(D2<>"",E2<>""),ROUND((D2-E2)/D2,2),"")
This checks that both Original Price and Current Price are filled, then calculates (Original - Current) / Original as a decimal. Format column F as Percentage to display it as "25%" instead of "0.25". Drag this formula down column F for all 500 rows to prepare for data entry.
Step 3: Add Conditional Formatting for Visual Alerts
Make your spreadsheet visually scannable by highlighting deals based on discount depth:
- 1.Select column F (Discount %)
- 2.Format → Conditional formatting
- 3.Add rule: Format cells > Greater than 0.30 → Light green background
- 4.Add rule: Format cells > Greater than 0.50 → Dark green background with bold white text
- 5.Add rule: Format cells > Less than 0.10 → Light red background (low discount warning)
Now, whenever you enter or update prices, the discount column automatically changes color to show deal quality at a glance.
Step 4: Import Data Automatically with IMPORTXML
For stores that expose price data in their HTML, you can use Google Sheets IMPORTXML to pull prices automatically. In a new sheet named "Auto-Import," enter formulas that scrape target product pages. Note: this requires basic XPath knowledge and works only on sites that do not block scrapers. Most major retailers block automated scraping, so this step is optional and primarily educational.
A more reliable automation approach uses Google Apps Script. Create a script (Extensions → Apps Script) that runs daily via a time-driven trigger, fetches prices from an API or structured data source, and updates your sheet. This requires intermediate programming knowledge but delivers fully automated tracking without manual data entry.
Step 5: Create a Dashboard Summary
In a new sheet named "Dashboard," build an at-a-glance overview of your deal landscape:
| Dashboard Metric | Formula Example | Purpose |
|---|---|---|
| Total Active Deals | =COUNTIF(L:L,"Active") | Track how many items you are monitoring |
| Average Discount | =AVERAGEIF(L:L,"Active",F:F) | See overall deal quality across your tracker |
| Best Category | =INDEX(C:C,MATCH(MAX(F:F),F:F,0)) | Identify which category has deepest discounts |
| Potential Savings | =SUMPRODUCT((L:L="Active")*(D:D-E:E)) | Total dollars saved if you bought everything |
| Alerts Triggered | =COUNTIF(F:F,">"&J:J) | Count items below your threshold |
Step 6: Set Up Email Alerts with Apps Script
Create a Google Apps Script that checks your Alert Threshold column (J) against current Discount % (F) daily. When an item's discount exceeds your threshold, the script sends you an email with the product name, store, current price, and direct URL. Schedule this script to run every morning at 6 AM using a time-driven trigger (clock icon in the Apps Script editor).
This automation is the closest DIY equivalent to litbuy spreadsheet's built-in alert system. It requires approximately 30 minutes to set up initially and zero maintenance afterward. Detailed code templates are available in the Google Workspace developer documentation under "Spreadsheet email alerts."

Frequently Asked Questions
Is building my own clone legal?
Yes. Creating a personal deal tracker for your own use using publicly available data is completely legal. Scraping data may violate some retailers' Terms of Service, which is why we recommend manual entry or API-based approaches. Never scrape sites that explicitly prohibit it.
Can I share my custom sheet with friends?
Yes, through Google Sheets sharing settings. However, if your sheet becomes a public commercial service, ensure you comply with data source attribution requirements and do not violate retailers' terms. Personal sharing among a small group is universally acceptable.
How often should I update prices manually?
For active deal hunting, update tracked items every 2-3 days. For passive monitoring, once per week is sufficient. If you are tracking flash sales or limited drops, daily updates are necessary. Consider the 30-60 minutes of manual entry as the "cost" of full customization versus using the automated official tool.
Will my custom tracker ever match the official litbuy spreadsheet?
Functionally, yes — you can build comparable sorting, filtering, and alerting. In terms of data volume and real-time accuracy, no. The official platform has dedicated infrastructure updating 10,000+ items across multiple stores every few hours. A DIY sheet is best viewed as a personal supplement, not a replacement, for the official tool.
Conclusion

The DIY approach delivers unlimited customization and complete data ownership at the cost of setup time and manual maintenance.
For most users, the official free litbuy spreadsheet offers better time-value efficiency with zero setup friction. Use the DIY approach as a learning exercise or supplement, not a replacement.
