A data analyzer tool is a web-based application that helps you understand your datasets by automatically analyzing their structure, content, and quality. It performs statistical calculations, detects column types, identifies data quality issues, and provides comprehensive insights about your data without requiring manual inspection or coding.
Simply drag and drop your CSV or JSON file onto the upload area, or click to browse and select the file. The analyzer will automatically process your data and display comprehensive statistics, including row counts, column analysis, data types, unique values, null counts, and statistical measures for numeric columns.
The data analyzer supports CSV (Comma-Separated Values) and JSON (JavaScript Object Notation) files. Both formats are commonly used for storing tabular data and are compatible with most spreadsheet applications, databases, and data analysis tools. Files up to 10MB are supported.
For numeric columns, the analyzer calculates minimum, maximum, mean (average), median, mode, and standard deviation. For all columns, it counts unique values, null values, and shows the top 5 most frequent values with their occurrence percentages. It also provides dataset-level statistics like total cells, empty cells, and duplicate rows.
The analyzer automatically examines the values in each column to determine if they are numbers, dates, booleans, strings, or mixed types. It uses an 80% threshold - if 80% or more of non-empty values match a specific type, the column is classified as that type. This helps you quickly understand your data structure.
Yes! You can copy the analysis report to your clipboard or download it as a text file. The report includes all statistics, column analysis, top values, and data quality metrics. Use the Copy Report button for quick sharing or Download Report button to save the analysis for later reference.
The analyzer offers three view modes: Overview shows dataset-level statistics and data quality metrics; Columns displays detailed analysis for each column including type, statistics, and top values; Preview shows the first 10 rows of your data in a table format. Switch between modes to explore different aspects of your dataset.
Absolutely! All data analysis is performed entirely in your browser using JavaScript. Your files are never uploaded to any server or transmitted over the internet. The data remains completely private and secure on your device. Once you close or refresh the page, all data is cleared from memory.
