About Tablecruncher
Tablecruncher is a lightweight yet powerful CSV editor for Mac, designed to handle large datasets efficiently. It can open files larger than 2GB, containing over 15 million rows, with a 100MB CSV file loading in under 5 seconds on a dual-core MacBook Pro. It supports various encodings, including UTF-8, UTF-16LE, UTF-16BE, Latin-1 (ISO-8859-1), and Windows 1252, automatically detecting most CSV formats and encodings. Users can utilize JavaScript as a macro language to manipulate CSV files, accessing all cells for content changes and calculations. Tablecruncher allows exporting table data to JSON, producing an array of objects if a header row is present, or an array of arrays otherwise. The find and replace dialog supports pattern searches within the table or selected areas, with Regular Expressions compliant with the ECMAScript 5 standard. It offers four color themes, including a dark mode compatible theme, enhancing user experience.
