Data cleaning shouldn't take days, weeks, ... months!

Inconsistent categories, missing values, unclear variable definitions, and messy spreadsheets slow down research, audits, and analysis. Preparing your data shouldn't require advanced analytics tools or technical expertise - it should be simple, guided, and accessible.

A guided workflow that fixes your data

Import your spreadsheet - Excel or CSV, no setup required.
Define your codebook - simple wizard for variable types, categories, and rules.
Auto-fix messy values and typos - "Yess" → "Yes", "Nooo" → "No", and more.
Resolve remaining issues - guided interface, no hunting through rows.
Preview full dataset - free tier shows all rows read-only.
Export to Excel - formatted header row with codebook legend.

AI that helps - but only when you want it

AI is completely optional and off by default. When you choose to enable it, the app sends only tiny, carefully selected samples - such as column names or unique values - to Azure OpenAI. Your full dataset never leaves your device.

With AI enabled, you get faster suggestions for variable types, category detection, value mapping, and clearer explanations of issues in your data. It's a way to speed up the tedious parts of cleaning while keeping you fully in control of every decision.
