How to Prepare Your Raw Google Sheets™ 
To ensure a smooth merge, follow these simple steps:
✅ Make Sure Files Are in Google Sheets™ Format
Files must be Google Sheets (not Excel). If you're uploading Excel files to Google Drive, turn on this setting:
Go to Google Drive™
Click the gear icon > Settings
Turn ON the toggle for: “Convert uploads to Google Docs™ editor format”
This ensures all uploaded Excel files are converted into Google Sheets™.
🗂️ Same Structure, Same Headers
All files should follow the same structure and column headers (e.g., Name, Quantity, Date).
Column names must match exactly (spelling, spaces, etc.)
📌 Organize File Name
Example: ABC - 10 March 2024 
We'll extract "ABC - 10 March 2024” as source file name .
🔄 Data Must Be in Vertical Format (Top-Down)
Each row should represent one data entry (e.g., a product, a transaction, a name, an entry).
The first row should be your header (column titles).
Do not arrange your data sideways (columns as entries). If unsure, think of your data like a spreadsheet you'd use for pivot tables — each row = 1 record.
