Inspect CSV columns, inferred data types, missing values, duplicate rows, and descriptive summaries without uploading the file.
Your selected file is processed locally in your browser. ScholarTool does not upload the file to a third-party calculation or data-analysis API.
Selecting a file only records file details. Click Load CSV to parse and preview input.
Drag and drop is optional; the normal file chooser is the primary accessible control.
Results, visuals, downloads, and copy actions remain hidden until Analyze CSV succeeds.
Load a CSV file to enable processing options.
CSV data profiling is a first-pass examination of a tabular file's rows, columns, headers, inferred types, missing values, uniqueness, duplicates, and numeric distributions. It helps reveal structural and quality issues before cleaning, visualization, statistical analysis, or model preparation.
CSV Data Profiler applies this concept to its defined inputs and workflow. It loads a local CSV file only after you click Load CSV, then runs profiling only when you click Analyze CSV.
After the user explicitly loads local data, the tool applies the selected workflow to local CSV file and returns profile summary, column table, missing-value visual, and summary CSV. Input structure, labels, missing values, and selected options must match the intended workflow. The output should be compared with the source file and the assumptions of the intended analysis before any transformation is accepted. Type inference is a heuristic and does not infer locale-specific dates.
The CSV Data Profiler loads a local CSV file only after you click Load CSV, then runs profiling only when you click Analyze CSV. It summarizes row and column counts, inferred data types, missing values, unique values, duplicates, and numeric distribution metrics.
ScholarTool parses the CSV with Papa Parse, assigns stable internal column IDs, excludes configured missing tokens from type inference, and uses conservative heuristics for integers, numbers, booleans, ISO dates, text, empty, and mixed columns.
Load a sensor CSV with time, pressure, temperature, and status columns. Analyze CSV to find missing temperature cells, duplicate sensor rows, and which columns are numeric before cleaning or modeling.
This tool is intended for educational, estimation, and preliminary data-preparation use. Always verify critical data-processing decisions with validated workflows and qualified professional judgment before using results in real research, compliance, or engineering decisions.
