Free Data Tools for Data Analysts

Data analyst tools in your browser: profile data quality, compare files, clean and join tables, convert Parquet and ask questions about a file. Free, no upload.

The problem

Analysts spend much of their time checking and cleaning data before any analysis. A fast check saves hours of wrong results.

Typical jobs: profile a file for missing values and outliers, compare two versions, join tables on a key, convert Parquet to CSV, and ask Chat with Data a question about a file.

Tools that help

Every tool runs in your browser and nothing is uploaded.
