Build Your Own Litbuy Spreadsheet from Scratch

Not everyone wants a pre-built tool. Some shoppers prefer the control, customization, and satisfaction of building their own litbuy spreadsheet from scratch. Whether you want to learn the underlying mechanics, create a version tailored to your exact preferences, or simply enjoy the DIY process, this comprehensive guide will teach you how to build a functional litbuy spreadsheet using free tools and publicly available data. No coding required for the basic version. Programming optional for advanced automation.

What You Will Need

To build your own litbuy spreadsheet, you need three things: a Google account (for Google Sheets), approximately 2 to 3 hours of focused time for the initial build, and basic spreadsheet familiarity (formulas, sorting, filtering). For the advanced automated version, you will also need a free OOCBuy API key and about 1 hour of additional setup time. Everything else is free.

The DIY approach is ideal for users who want to understand every column and formula, add custom categories not covered in the standard tool, integrate with their personal budgeting system, or simply enjoy the learning process. If your goal is purely to save money with minimal effort, the pre-built litbuy spreadsheet is a better choice. This guide is for the builders and tinkerers.

Step 1: Create the Foundation Sheet

Open Google Sheets and create a new blank spreadsheet. Name it My Litbuy Tracker. In the first row, create these column headers: Item Name, Category, Brand, Original Price, Current Price, Discount %, Seller Name, Seller Verified (Yes/No), Product Link, Date Added, Notes. These 11 columns capture all the essential information needed for effective deal tracking.

Format the header row with bold text and a light background color for easy scanning. Set the Discount % column to percentage format. Freeze the first row so it remains visible when scrolling. Apply data validation to the Category column with a dropdown list containing your chosen categories: Shoes, Hoodies, T-Shirts, Jackets, Pants, Headwear, Sets, Underwear, Jersey, Accessories.

Step 2: Add Automatic Calculations

The Discount % column should calculate automatically. In cell F2, enter the formula: =(D2-E2)/D2, then copy it down the entire column. This calculates what percentage the current price is below the original price. Next, add conditional formatting to highlight the best deals. Select the Discount % column, open conditional formatting, and set rules: green background for values above 0.5 (50% off), yellow for 0.25 to 0.5, and red for below 0.25.

Add a Summary Dashboard at the top of your sheet or on a separate tab. Use COUNTIF formulas to show total items tracked, average discount percentage, and number of verified sellers. These summary metrics give you instant insight into your deal landscape without manual counting.

Step 3: Populate with Initial Data

The manual method involves visiting OOCBuy, browsing each category, and copying deal information into your sheet one row at a time. This takes about 30 minutes per category for 20 items. Alternatively, use our free OOCBuy Import Script, which automatically populates your sheet with live deal data every 6 hours. The script is available on our GitHub repository with step-by-step installation instructions.

Step 4: Build Filtering Views

Create filtered views for each category you shop most frequently. In Google Sheets, go to Data > Filter Views > Create New. Name each view after a category and set the filter condition to Category equals [category name]. This gives you one-click access to shoes-only, hoodies-only, or any other focused view. Create an additional filtered view for Best Deals showing only items with discount above 40%.

Step 5: Add Price History Tracking

Price history is what transforms a simple list into a real deal tracker. Create a new sheet named Price History. Each time you refresh your data, copy the current prices column and paste it as values into the next column of your history sheet, with the date as the header. Over weeks and months, you will build a visual price trend chart that helps you identify the optimal purchase timing. This is the core feature that makes litbuy spreadsheet genuinely useful for saving money.

DIY vs Pre-Built Comparison

Step 6: Automate with Google Apps Script

For users who want their DIY spreadsheet to update automatically, Google Apps Script is the solution. Open Extensions > Apps Script in your sheet. Copy our free import script from GitHub, paste it into the editor, and set a trigger to run every 6 hours. The script fetches live deal data from OOCBuy and populates your sheet automatically. You will still need to review and verify seller information manually, but the data collection becomes effortless.

Advanced users can extend the script to send email alerts when discounts exceed a threshold, export weekly summaries, or even post deals to a personal Slack channel. The possibilities are limited only by your creativity and scripting ability. Our community forum has dozens of user-contributed script extensions for every use case imaginable.
