CommaForge is a fully offline CSV toolbox for iPhone and iPad. Every operation runs locally on your device, with no network access, no data collection, no ads, and no in-app purchases. Convert CSV files to JSON, XML, Markdown tables, HTML tables, TSV, Plist, or SQL INSERT statements, and convert JSON or TSV back to CSV. Switch delimiters freely between comma, semicolon, tab, and pipe. Automatically detect and repair encoding issues in Excel-exported files across UTF-8, GBK, Big5, and Latin-1. Preview large spreadsheets with a frozen header row, delete rows and columns, reorder columns, remove duplicates, and drop empty lines. Split oversized CSV files by row count and merge multiple files into one with column consistency checks. Import from the Files app or the share sheet, and export results through the system share sheet or save directly back to Files. Reusable presets and history make repeat conversions instant. Dark Mode and Dynamic Type are fully supported.
