How to Use the Universal Dataset Generator: A Step-by-Step Guide
This generator provides a streamlined way to get common types of datasets. Here’s how to use it:
1. Choose Your Dataset Type & Record Count
-
Select Dataset Type:
- Purpose: Choose from a variety of pre-configured dataset structures covering different domains (e.g., “Simple Sales Data,” “Basic Employee Data,” “Website Traffic”). The options are grouped into categories like “General Business,” “Web & Marketing,” “Project Management,” etc., for easy navigation.
- Usage: Click the dropdown and select the dataset that best fits your practice scenario.
-
Number of Records:
- Purpose: Specify how many rows (records) you want in your generated dataset.
- Usage: Enter your desired number. The tool enforces a minimum of 10 records and a maximum of 50,000 records. Values outside this range will be automatically adjusted.
-
Generate Data Button:
- Purpose: Initiate the data generation process based on your selected type and record count.
- Usage: Click the prominent “Generate Data” button. A loading message will appear, and once complete, the data preview will update.
2. (Optional) Adjust Advanced Options
Click on the “Advanced Options” summary to expand this section and reveal additional settings:
-
Date Range (From / To):
- Purpose: Define the time frame for any date-related columns within your chosen dataset.
- Usage: Use the date pickers to select your desired “From” and “To” dates. Ensure the “From” date is earlier than the “To” date to avoid errors.
-
Data Quality:
- Purpose: Simulate real-world data imperfections, which is crucial for practicing data cleaning and error handling.
- Usage: Select one of the following options:
- Clean: Generates data with no intentional errors or inconsistencies.
- Slightly Messy (5% errors): Introduces a small percentage of duplicate rows, blank values, “#N/A” errors, or extra spaces in string fields.
- Very Messy (15% errors): Introduces a higher percentage of the above-mentioned data quality issues.
3. Review and Download Your Data
After clicking “Generate Data”:
-
Data Preview:
- Purpose: See a sample of your generated data (typically the first few rows) to ensure it matches your expectations.
- Location: The preview will appear in the “Data Preview” section at the bottom of the page.
-
Copy Preview:
- Purpose: Quickly copy the previewed data (as tab-separated text) to your clipboard for pasting into spreadsheets or text editors.
- Usage: Click the “Copy Preview” button. A “Copied!” message will briefly confirm the action.
-
Download CSV:
- Purpose: Download the entire generated dataset in Comma Separated Values (CSV) format. This is a common, lightweight format compatible with almost all data tools.
- Usage: Click the “Download CSV” button. The file will be named according to your selected dataset type (e.g., Simple_Sales_Data_Dataset.csv).
-
Download Excel:
- Purpose: Download the entire generated dataset in Microsoft Excel (XLSX) format. If your chosen dataset type includes “related tables” (like Products or Customers for Simple Sales Data), these will be included as separate sheets within the same Excel file.
- Usage: Click the “Download Excel” button. The file will be named accordingly (e.g., Simple_Sales_Data_Dataset.xlsx).
