How it Works
Choose a Template or Build a Schema
Pick from ready-made templates like E-Commerce, HR, or CRM — or build your own schema by adding the exact columns you need. Use AI to generate a schema from a text description.
Configure Your Columns
Set the data type for each column — Name, Email, Phone, Address, Number, Date, Custom List, UUID, and more. Use AI rules to generate custom text like product descriptions or feedback.
Set Row Count & Preview
Choose how many rows of fake data to generate (up to 5,000). The live preview updates in real time so you can see exactly what your data will look like before downloading.
Download in Your Format
Download your generated dataset as an Excel spreadsheet, CSV file, JSON array, SQL INSERT statements, or XML — all with one click. No account or email required.
FAQs
What types of fake data can I generate?
You can generate: First Name, Last Name, Full Name, Email Address, Phone Number, Street Address, City, State, Country, Postal/ZIP Code, Company Name, Job Title, Date Range, Number Range (with min/max), Incrementing ID, UUID (unique identifiers), Custom List (your own options), Paragraph Text, and AI-generated text based on a custom rule.
How many rows of dummy data can I generate?
You can generate up to 5,000 rows of standard dummy data instantly in your browser. For AI-generated column rules, the limit is 100 rows per generation to stay within API time limits.
What file formats can I download the generated data in?
You can download your dummy data as: Excel (.xlsx), CSV (comma-separated values), JSON (array of objects), SQL (INSERT INTO statements), and XML. All formats are generated instantly in your browser.
Can I use AI to generate the schema for me?
Yes. Type a description of the dataset you want — for example, 'Generate a sales dataset with customer name, product, quantity, price, and payment method' — and our AI will automatically create the correct columns and data types for you.
What are the pre-built templates?
We offer five ready-made templates: E-Commerce Orders (Order ID, Date, Customer, Product, Price, Status), HR Employee Roster (Employee ID, Name, Job Title, Department, Salary), Customer CRM Leads (Contact Name, Company, Industry, Lead Score, Status), Student Grade Registry (Student Name, Subject, Grade, Attendance), and Product Catalog (SKU, Product Name, Category, Price, Stock, Rating).
What is an AI Column Rule?
An AI Column Rule lets you write a custom instruction for generating text in a column — for example, 'Write a one-sentence product description for a household appliance' or 'Write a short customer review (positive)'. The AI generates a unique response for each row.
Is the generated data realistic?
Yes. Name, email, phone, address, company, and other standard fields use realistic random generation patterns — so the output looks like real but completely fictional data. AI-generated columns produce fully unique, contextually appropriate text.
Is any of my data uploaded to a server?
No. All standard data generation happens entirely in your browser using JavaScript — nothing is sent to any server. Only AI column generation requires an API call to generate the text, and no personally identifiable information is ever sent.
Can I generate SQL INSERT statements for my database?
Yes. Choose SQL as your download format, enter your table name, and the generator will produce ready-to-run INSERT INTO statements with all your columns and generated values.
Can I save my schema for later?
Your schema is saved automatically in your browser session while the page is open. Currently, persistent saved schemas are not supported, but you can bookmark the page and rebuild quickly using the same template or AI prompt.
