Load a built-in sample dataset

Mammoth comes with sample datasets you can load in a few clicks: in your project, click New dataset and select Sample Files. They need no preparation, hold no sensitive data, and give a team identical data to practise on or demo with. To describe your own test data instead, see Create test data with AI.

Load a sample dataset

New Dataset dialog with Sample Files selected and category tabs above cards such as Multi-Store Retail Sales
  1. Click New dataset in your project.
  2. Select Sample Files.
  3. Choose the All samples tab, or one of the Business, Technology, Finance & Real Estate, or Healthcare & Entertainment tabs, and read the descriptions.
  4. Click the card of the dataset you want. The card is highlighted; there is no data preview.
  5. Click Create new dataset. The dataset appears in the project, ready to explore.

Sample files need no preparation, hold no sensitive data, and give a team identical data to practise on. They are also useful for demos with familiar patterns.

Sample datasets you can load

Each sample is a CSV file of 25 to 63 rows, so it loads quickly and is easy to inspect.

First look at MammothMulti-Store Retail SalesFamiliar sales, products and regions; suits several transformations, data quality checks, aggregation and filtering
Advanced featuresE-commerce Multi-Channel or Supply Chain OptimizationMulti-source scenarios, standardization problems, harder calculations
Team trainingMatch your industry (Manufacturing to Quality Control, SaaS to Business Metrics)People recognise the patterns and problems
Client demosAn industry-specific datasetStakeholders recognise the data and the business problem

Tip: Choose sample data that matches your team's domain, for example a manufacturing quality dataset for an operations team.

Practise with a sample dataset

  1. Check data quality with Explore Cards: distributions, missing values, outliers and inconsistencies.
  2. Try several transformation types: cleaning (standardize company names), filtering (remove test data, focus on a region or period), aggregating (totals, averages, growth rates) and joining.
  3. Build an example pipeline: monthly sales reports (Multi-Store Retail), customer lifetime value (SaaS Business Metrics), campaign ROI (Social Media Campaign Performance) or quality tracking (Manufacturing Quality Control).

A first session takes about 15 minutes: pick Multi-Store Retail Sales (2 minutes), explore it with Explore Cards (5 minutes), build a filter pipeline (5 minutes), and generate a sales-by-region dashboard (3 minutes).

Tip: Build your demo pipeline on sample data before a client meeting. You can then repeat the same transformations on their actual data.

What sample files are not

  • They aren't your business data or production-ready datasets. They are learning tools and starting points.
  • They are smaller than production data, may not include every edge case, and are clean enough to focus on learning Mammoth rather than cleaning.

Move to your own data when you are comfortable with basic transformations, need to solve a specific business problem, or want to build production dashboards. Note which transformations worked on the sample, and start with a subset of your real data.
