Excel is great for small datasets, but manual cleaning becomes impractical when dealing with thousands of rows. Studies show data analysts spend 60-80% of their time cleaning data manually. CleanIQ uses AI to detect patterns across your entire dataset, finding inconsistencies that are nearly impossible to spot manually—like variations in date formats (01/15/2024 vs 2024-01-15 vs Jan 15, 2024) or misspelled company names. What takes hours in Excel takes seconds with CleanIQ.

CleanIQ offers multiple strategies for missing data: You can fill missing values with column averages/medians (for numerical data), mode (for categorical data), or use our AI to predict likely values based on patterns in other columns. You can also choose to flag missing values for manual review or remove rows with missing critical fields. Every change is tracked in an audit log so you can revert if needed.

Yes, but we go beyond simple exact-match detection. Our fuzzy matching algorithm identifies near-duplicates that differ slightly due to typos or formatting (e.g., 'John Smith' vs 'Jon Smith' or 'ABC Corp.' vs 'ABC Corporation'). You can configure matching thresholds and choose which fields to compare. We also help you decide which duplicate to keep based on data completeness or recency.

Security is our top priority. All data is encrypted in transit (TLS 1.3) and at rest (AES-256). We automatically detect and can mask sensitive data like emails, phone numbers, SSNs, and credit card numbers. Your data is stored in SOC 2 Type II certified data centers, auto-deleted after your retention period, and we never use your data to train our AI models. We're fully GDPR and CCPA compliant.

We support CSV, Excel (.xlsx, .xls), and TSV files. File size limits depend on your plan: 100MB (Starter), 1GB (Professional), and 10GB (Enterprise). For very large datasets, we process files in chunks to maintain performance. Google Sheets integration and direct database connections (PostgreSQL, MySQL) are on our roadmap for Q2 2024.

Our AI achieves 99.9% accuracy on standard data quality issues. However, we never apply changes automatically—you always preview suggestions first. Each suggestion shows the original value, proposed fix, and the AI's reasoning. You can accept individual changes, accept all, or reject ones you disagree with. The original data is always preserved until you explicitly export the cleaned version.

Yes, on Professional and Enterprise plans. You can define regex-based validation rules, create transformation templates (e.g., 'always format phone numbers as (XXX) XXX-XXXX'), and save these as reusable profiles. This is especially useful for recurring data imports where you want consistent cleaning rules applied automatically.

You can export cleaned data as CSV, Excel, or JSON—all formats work directly with Power BI and Tableau. We provide pre-built connectors for common workflows, making it easy to integrate cleaned data into your existing analytics pipelines.
