CSV Analyzers — for full-export analysis

When the calculator answers the question, the analyzer reveals the pattern. Five free in-browser analyzers that score a full CSV export.

Cloud & Infra Analyzer
Score every instance, volume, and transfer line in your AWS/GCP/Azure billing CSV. Surfaces oversized, idle, and anomalous spend ranked worst-first.
DevOps Health Analyzer
Score SLO compliance, burn rate trends, MTTR, and on-call distribution across your service catalog from one CSV.
Data Governance Analyzer
Score retention policies, PII exposure, and access patterns against compliance frameworks (GDPR, CCPA, SOX) from a data-inventory CSV.
Churn Defense Analyzer
Correlate satisfaction signals, crash patterns, and engagement decline with account-level risk. Surfaces accounts at risk before they churn.
Revenue Intelligence Analyzer
Score expansion potential, retention risk, and pricing-power signals across your account base from one revenue CSV.
