CSV & spreadsheet tools
Eight tools for CSV and spreadsheet files: merge, split, compare, and transpose CSV files, convert an Excel workbook to CSV or JSON, convert an HTML table to CSV, and turn CSV rows into ready-to-run SQL INSERT statements. All of it runs on your own device - your spreadsheet data is never sent anywhere.
