Introduction

Dataset To Schema Scraper analyzes dataset records, detects field types, and produces a complete JSON schema that reflects real-world data variability. It solves the problem of undocumented or inconsistent data structures by automatically generating an accurate schema. This project is ideal for data engineers, backend developers, and analytics teams working with evolving datasets.

Automated Dataset Schema Generation

• Scans all records to detect field names and data types
• Merges multiple datasets into a single unified schema
• Supports mixed and optional field types
• Outputs a ready-to-use JSON schema
• Designed for validation and consistency checks

Features

Feature	Description
Multi-dataset support	Generates a single schema from multiple datasets at once.
Type detection	Automatically detects strings, numbers, booleans, objects, and arrays.
Union types	Merges inconsistent field types into safe union definitions.
Schema export	Produces a complete JSON schema for reuse and validation.
Large dataset handling	Continues processing with warnings for extremely large datasets.

Use Cases

• Backend developers use it to validate API responses, ensuring consistent data contracts.
• Data engineers generate schemas to document datasets before analytics or ML pipelines.
• QA teams detect unexpected data changes early to prevent downstream failures.
• Product teams standardize data formats across multiple data sources.
• Platform engineers auto-generate schemas for validators and integrations.

FAQs

Can this tool handle multiple datasets at once? Yes, it merges all detected fields from multiple datasets into a single unified schema.

What happens if a field has different types across records? The schema safely merges them into a union type to reflect real data variability.

Is the generated schema suitable for validation? Yes, it follows standard JSON schema conventions and can be used for validators or APIs.

How does it behave with very large datasets? It continues processing while logging a warning that the schema may be partially sampled.
