Data profiling for Looker

What is data profiling for Looker and why is it important?

Data profiling for Looker involves systematically analyzing the datasets connected to Looker to assess their quality, structure, and content. This process uncovers key characteristics such as data distributions, missing values, uniqueness, and anomalies. Profiling helps ensure that the data powering Looker’s analytics is accurate and reliable, which is critical for making informed business decisions.

By understanding the condition of data through profiling, teams can prevent errors in reports and dashboards, ultimately improving trust in Looker’s outputs. It also supports ongoing data governance by identifying issues early and enabling timely corrections.

• Assess data quality: Detect missing or inconsistent values that could affect analytics accuracy.
• Understand data distribution: Reveal statistical patterns that inform better data modeling.
• Identify outliers: Highlight unusual data points that may skew insights.
• Support governance: Monitor data quality metrics to maintain compliance and standards.

How does data profiling enhance Looker’s analytics capabilities?

Integrating data profiling into Looker workflows improves analytics by confirming the integrity of the underlying data before visualization. This validation helps analysts and decision-makers trust that the insights reflect true business conditions rather than data errors.

Profiling also informs LookML developers about which fields to prioritize or exclude, optimizing data models for performance and relevance. Additionally, it fosters collaboration by providing shared visibility into data quality and lineage, aligning teams around a common understanding of the data.

• Reliable decision-making: Ensures dashboards represent accurate and meaningful data.
• Optimized data models: Guides inclusion of relevant fields to improve query efficiency.
• Early problem detection: Flags data quality issues before they impact reports.
• Cross-team alignment: Shares data insights to unify analysts, engineers, and business users.
