Import Wizard

Bring a CSV/XLSX file or a PostgreSQL connection into DataQloo as a reusable dataset, with column profiling before you commit.

What it does

The Import Wizard is a five-step flow: choose a source (upload a file, or use an existing or new PostgreSQL connection), configure it, preview the resulting rows, review a per-column profile, and save it as a named dataset.

The profiling step runs before you commit anything — for each column you see its inferred type, fill rate, count of unique values, null percentage, and either an average (numeric columns) or most common value (categorical columns), so you can catch data quality issues before building a workflow on top of it.

What it doesn't do yet

Only PostgreSQL is supported as a live database connection during import; other database and warehouse connectors are on the roadmap. File upload (CSV/XLSX/XLS) works today independent of that.

Common use cases

Upload a spreadsheet export and turn it into a queryable dataset
Connect a PostgreSQL table and register it as a dataset for reuse
Check data quality (fill rate, nulls, uniqueness) before building a workflow
