About this tool
Table analytics automatically computes descriptive statistics for every column in a tabular dataset — CSV, JSON, or Parquet. For numeric columns, it calculates min, max, mean, median, and standard deviation. For text columns, it shows the count of unique values, the most frequent values, and the null or empty count. This gives you an immediate overview of a dataset's structure and quality without writing any code or opening a data analysis tool.
