Capabilities

Everything you need to trust your data

From a single file upload to enterprise-grade data pipelines — CorePulse handles the entire quality lifecycle.

Exact & Fuzzy Duplicate Detection

Finds exact copies and near-matches using Levenshtein distance, Soundex phonetic matching, and token similarity. Catches 'Jon Smith' vs 'John Smith' automatically.

Missing Value Analysis

Identifies null, empty, and placeholder values across every column. Shows fill rates and flags fields that breach your quality thresholds.

Quality Score Dashboard

A single 0–100 quality score with column-level breakdowns. Track improvement over time as you clean and re-upload your data.

One-Click Cleaned Export

Download a deduplicated, validated Excel file instantly. Rows annotated with issue flags so your team knows exactly what changed.

AI-Powered Insights

Executive-ready summaries and prioritized recommendations generated automatically — no manual analysis required.
