Synthetic data generation is the process of generating an artificial dataset that is similar to real-world data, but it has no privacy risks.
It lets you tap into new possibilities for AI, analytics, and research. If you’ve ever felt stuck waiting for real data, or worried about privacy issues, you’re in the right place: generating synthetic data is simpler and far more practical than you might think.
In this blog, we will show you 5 simple steps to generate practical synthetic datasets. Let’s go!
Step 1: Decide What You Need Your Synthetic Data To Do
Before you start generating anything, take a moment to think about why you want synthetic data in the first place. Answer these questions:
- What problem do you need to solve?
- Are you training a machine learning model for fraud detection, running simulations for healthcare, or building a dashboard for developer productivity?
When you know your purpose, it will help you outline the schema, variable types, and volume of data you need. You also need to:
- Define your use case: e.g., image generation for computer vision, tabular data for boosting AI model accuracy, or time-series data for predictive analytics.
- List important features: What columns, fields, or events do you need? You should focus on what truly drives your analysis or model.
- Set a target size: Will you need 1,000 samples or 1,000,000? Synthetic data is scalable to fit any project.
Pro tip: Write down at least 4–6 must-have variables you want in your dataset. This will help keep your process focused and efficient.
Step 2: Gather Reference Data or Use Domain Knowledge
Synthetic data will be useless if the data that you feed is not proper.
Remember that quality synthetic data generation works best when it’s based on reality. If you have access to real data (even a small sample), you can use it to analyze distributions, correlations, and edge cases. If not, rely on your domain knowledge or research to mimic realistic scenarios. Here’s how you can go around it:
- Analyze real data: Look at averages, ranges, missing values, and typical feature relationships.
- Use domain expertise: If real data isn’t available, talk to field experts and review published studies to capture authentic patterns.
- Identify constraints and business rules: These could be things like “age must be a positive integer” or “credit limit shouldn’t exceed $50,000 for student accounts.”
Step 3: Choose Your Synthetic Data Generation Method
Now, turn your schema and research into a synthetic data generation strategy. There’s no “one size fits all”. So, you have to choose a method that matches your technical skill, purpose, and available tools. There are many options available for Synthetic data generation:
1. Rule-based synthesis
This is the simplest way to generate synthetic data. You basically define a set of “if-then” rules or even use a spreadsheet to simulate the behavior you want.
For example: If age < 18, set occupation as ‘student’. It works well for small, straightforward tasks where you want complete control and transparency.
2. Statistical modeling
Here, you go a step further. Instead of fixed rules, you generate values by sampling from probability distributions (normal, uniform, binomial, etc.).
This makes your dataset look and feel more realistic because of the natural variance it introduces. It’s useful when you already have a reference dataset and want your synthetic version to match its patterns and spread.
3. Generative AI models
This is where things get powerful. With tools like advanced models such as GANs (Generative Adversarial Networks) and VAEs (Variational Autoencoders), you can generate huge, diverse, and complex datasets.
These models actually learn from real data and then create new samples automatically. If you’re working with multimodal data (text, images, or structured + unstructured combined), this is the way to go.
4. Dedicated synthetic data platforms
This is where things get interesting. Platforms like Syncora.ai offer a complete solution for small to enterprise-level dataset generation. Syncora’s agentic workflow automates everything: schema detection, rule-building, distribution fitting, and even compliance checks.
The result? You get high-fidelity, privacy-safe data with just one click and under 2 minutes! This is perfect for teams that need scalability, speed, and want to meet strict regulatory compliance without doing all the manual heavy lifting.
Step 4: Generate, Explore, and Validate Your Data
It’s time to synthesize your dataset! Depending upon the data generation method you chose, you may have to follow certain processes and steps. When you’re in that process, remember that you don’t just “generate” and walk away. You need to dig in to understand what’s being created.
- Run the generation: Use your code or platform to make the dataset. Whether that’s 1,000 developer productivity records, 10,000 credit card transactions, or 1M customer profiles.
- Visual inspection: Check basic statistics like means, standard deviations, histograms, and missing data rates to make sure your dataset feels natural.
- Advanced validation: Use tools like pandas-profiling, Great Expectations, or Syncora.ai’s automated validator to catch issues, spot outliers, and ensure realistic relationships between features.
- Privacy assurance: Confirm that your dataset contains no actual personal information, is fully synthetic, and complies with privacy requirements (GDPR, HIPAA, etc.).
You can also plot a few graphs or run summary tables to spot odd patterns (e.g., negative ages, duplicate records, unrealistic values).
Step 5: Deploy or Tune And Keep Improving
You’re almost done. Now you can put your synthetic data to work.
- Integrate into your workflow: Use the dataset for model training, benchmarking, dashboard development, or software testing.
- Collect feedback: If you’re working with collaborators, let them review the data. Check if the features and distributions are correct and if it is truly privacy-safe. If you used Syncora for data generation, the AI agents will automatically validate your data for accuracy and edge cases. Plus, if you license your dataset on the marketplace, real validators will also validate your data.
- Tune your generator: Based on feedback or test results, adjust constraints, distributions, or generation logic to fix any problems.
- Document everything: Log your process, parameters, and purpose. This builds trust and repeatability for auditors, regulators, or future team members.

FAQs
What is synthetic data generation, and why should I use it?
Synthetic data generation is the process of developing artificial datasets that mirror real-world patterns while protecting actual people’s privacy. You can use it to accelerate AI development, mitigate privacy issues, test edge situations, and scale trials when real data is limited.
How do I choose the right synthetic data generation method?
You can choose a synthetic data generation method as per your goals and data type:
- Rule-based: if you want full control and transparency.

- Skip schema and constraints (types, ranges, business rules).
- Ignore correlations (e.g., income vs. spend).
