About CSV Analyzer
CSV Analyzer reads CSV data and profiles each column: inferred data type (integer/number/boolean/date/string), missing-value count, and cardinality (unique values). It also detects ragged rows (inconsistent column counts) and duplicate rows.
Useful for data-quality checks before import or processing.
FAQ
Is my data sent to a server?
No. The entire analysis runs in your browser with JavaScript. Nothing is uploaded, logged, or stored on our servers — safe for sensitive data.
How is this analyzer different from a parser, validator, or viewer?
An analyzer produces an insight report — metrics, statistics, warnings, and recommendations — to help you judge the quality or characteristics of the input. A parser breaks it into structure, a validator gives a valid/invalid verdict, and a viewer just displays it. An analyzer focuses on "how good / what are its characteristics".
