Creating dummy data with Gemini is highly effective because it can generate structured, realistic records that fit your specific app schema.
Here are the two best ways to do this:
Method 1: Direct “Export to Sheets”
-
Prompt Gemini: Ask for your data in a table format.
Example: “Create a dummy dataset for a construction project tracker. Include 20 rows with columns: Project Name, Site Manager, Start Date, Status (Planned, In Progress, Complete), and Estimated Budget. Format it as a table.” -
Export: Once Gemini generates the table, look for the Google Sheets icon or the “Export to Sheets” button at the bottom-left of the table.
- Finalize: A new Google Sheet will open in your Drive with the data perfectly formatted. You can then connect this Sheet to AppSheet as a data source.
Method 2: Create a CSV file
-
Prompt Gemini: Ask for a CSV-formatted code block.
Example: “Generate a dummy dataset of 15 inventory items for a retail store. Provide it as a CSV code block with headers: Product_ID, Item_Name, Category, Stock_Level, and Reorder_Point.” -
Copy the Code: Click the “Copy” button on the top-right of the code block Gemini provides.
-
Paste it into cell A1 of a new Google Sheet.
-
Select Column A.
-
Go to Data > Split text to columns.
Note: Utilize Method 2 whenever Method 1 is not displayed as an option in the generated response.
