About

RowCove is a native desktop application for inspecting and editing large local data files on Windows and Apple Silicon Macs. It opens structured formats including CSV, TSV, JSON, JSONL/NDJSON, Parquet, Arrow IPC and Feather, and provides table and nested-value views for reviewing records. Users can filter and sort files, inspect partition and source context in supported shards, and stage supported changes before saving a separate copy. The application is designed for data engineers, AI dataset practitioners, quantitative researchers and analysts who need to examine exports or research data without first converting them to another format. RowCove also provides authorized local Model Context Protocol (MCP) tools for compatible AI clients, including schema access, test calls, wire logs and history. Processing is performed locally; available features and performance depend on file format and system hardware.

About

​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.
