Who should use the Data Validation workflow?
Teams or solo builders working on data tasks who want a repeatable process instead of one-off tool experiments.
AI Workflow · Data
A focused workflow to generate synthetic data, validate its schema, and apply validation rules to ensure data quality and integrity.
Deliverable outcome
An automated, hands-off validation pipeline that runs on a schedule or event trigger.

Step map
Instead of relying on a single generic AI model, this pipeline connects specialized tools to maximize quality. First, you'll use Rossum to a documented specification that serves as the single source of truth for all validation steps. Then, you pass the output to Tonic AI to a synthetic dataset with a known ground truth of valid and invalid records. Then, you pass the output to Instructor to a schema validation report listing all passes and failures, with exact row/column references. Then, you pass the output to Hex Magic AI to a detailed rule-by-rule validation output showing pass/fail counts and sample failing rows. Then, you pass the output to Anomalo to a cleaned validation report with all failures explained and resolved, plus updated specifications. Then, you pass the output to Tableau AI to a comprehensive, shareable validation report that can be used for audit or integration into ci/cd pipelines. Finally, Prefect is used to an automated, hands-off validation pipeline that runs on a schedule or event trigger.
Define Validation Requirements & Data Specifications

Review & Remediate Validation Failures
A cleaned validation report with all failures explained and resolved, plus updated specifications.
Generate Validation Summary & Quality Report
A comprehensive, shareable validation report that can be used for audit or integration into CI/CD pipelines.
Automate Validation Pipeline (Optional)
An automated, hands-off validation pipeline that runs on a schedule or event trigger.
Start by documenting the expected schema (field names, data types, constraints) and the business validation rules (e.g., range checks, uniqueness, referential integrity). This step ensures all downstream validation has a clear target. Gather input from stakeholders or existing data dictionaries.
Why Rossum: Rossum provides document classification and data extraction capabilities that can help define validation requirements and data specifications from existing documents, plus it includes validation features.
Use a synthetic data generator (e.g., Faker, SDV, or custom script) to produce a dataset that mimics real data but includes intentional edge cases and anomalies. Inject a controlled set of violations (e.g., missing values, out-of-range numbers) to test validation rules.
Why Tonic AI: Tonic AI specializes in synthetic data generation, data masking, and test data subsetting, making it ideal for generating synthetic data with known characteristics.
Run automated checks against the synthetic dataset to verify that every field matches the defined schema: correct data types, required fields present, and no extra columns. Use a schema validation library (e.g., Great Expectations, Pandera, or SQL DDL).
Why Instructor: Instructor provides structured data extraction and type-safe code generation, which can be used to validate schema compliance through structured outputs.
Apply the predefined business rules (e.g., range checks, uniqueness, cross-field logic) to the dataset. For each rule, record which rows pass or fail, and summarize the violation rate. Use a rule engine or custom assertions.
Why Hex Magic AI: Hex Magic AI enables natural language to SQL generation and Python data manipulation, which can be used to implement and execute business validation rules.
Analyze the validation results to distinguish between genuine data quality issues and false positives. For synthetic data, this step confirms that the injected violations were correctly caught. Document any unexpected failures and adjust rules or generation logic accordingly.
Why Anomalo: Anomalo specializes in data quality monitoring, anomaly detection, and data validation, making it ideal for reviewing and remediating validation failures.
Compile all findings into a final report that includes schema compliance rates, rule pass/fail percentages, and a data quality score. This report serves as documentation for stakeholders and as a baseline for future validation runs.
Why Tableau AI: Tableau AI provides data analysis, data visualization, and predictive modeling, ideal for generating comprehensive validation summaries and quality reports.
Wrap the validation steps into a repeatable script or pipeline (e.g., using Airflow, Prefect, or GitHub Actions) so that future synthetic or real datasets can be validated automatically. This step is optional but recommended for production workflows.
Why Prefect: Prefect is a dedicated workflow orchestration and data pipeline management tool, perfectly suited for automating validation pipelines.
§ Before you start
Teams or solo builders working on data tasks who want a repeatable process instead of one-off tool experiments.
No. Start with the top pick for each step, then replace tools only if they do not fit your pricing, compliance, or output needs.
Open the mapped task page and compare top options side by side. Prioritize output quality, integration fit, and predictable cost before scaling.
