Data validation tool

AI Data Validation Tool for Excel, CSV, and PDF Files

ainomaly.io reviews business files for the problems people usually catch too late: outliers, missing values, duplicate charges, sudden cost spikes, and inconsistent records.

Built for file review

Upload, analyze, review, decide.

  • Upload Excel, CSV, TXT, or PDF files
  • Get a concise AI summary plus structured anomaly rows
  • Uploaded files are not retained after processing

What the AI checks

The analyzer looks for statistical outliers, irregular patterns, missing or invalid data, unusual trends, duplicate-looking values, and billing or reporting lines that deserve human review.

  • Financial reports, invoices, exports, and operational spreadsheets
  • Cloud, utility, and recurring service bills
  • CSV imports before they enter downstream systems

How it works

Describe where the file came from, upload the file, and receive an explainable summary with any flagged anomalies. Results are designed for quick review, not for replacing financial, legal, or compliance judgment.

  • PDF pages, spreadsheet rows, and text size are converted into page usage
  • Paid plans include higher page allowances and API access
  • Analysis results can trigger in-app and email notifications

What is a data validation tool?

A data validation tool checks whether data is complete, plausible, consistent, and ready for use. ainomaly.io focuses on file-based validation for Excel, CSV, TXT, and PDF uploads.

Does ainomaly.io replace Excel data validation rules?

No. Excel rules are useful while entering data. ainomaly.io reviews completed files and exports for anomalies, missing values, spikes, and patterns that rules may not cover.

Uploaded files are processed for analysis and are not retained afterward. Analysis results and usage data may be stored so the product can show results, billing, and account history.
