QuickSheet is a local-first universal grid editor for CSV, TSV, delimited text, value-focused XLSX, structured data, and configuration files on iOS and macOS. It prioritizes data fidelity: values remain literal unless you calculate, format mappings are shown before import, and save or export behavior is explicit. KEY FEATURES: - Delimited-text fidelity: Preserve leading zeros, long identifiers, date-like strings, encoding, delimiter, newline, BOM, quote, and escape style. - 14 grid formats: Work with CSV, TSV, DSV, XLSX, JSON, JSON Lines, Properties, INI/CFG, .env, XML, YAML, TOML, Markdown tables, and text tables. - Structured mappings: Review how records, trees, properties, attributes, comments, and tables map into the grid before editing. - Large-file workflow: Stream rows into temporary local storage so search, filter, sort, and scrolling remain practical; open sensitive or large files Read-Only first. - Import Preview and profiles: Confirm encoding, delimiter, quote, header, skipped rows, mapping, and save fidelity, then reuse trusted choices per file. - Value-focused XLSX: Open multiple sheets as values and formula text with clear compatibility limits instead of claiming full presentation fidelity. - Grid tools: Edit formulas, inspect dependencies and problems, find and replace, filter, sort, fill series, preview paste, manage rows and columns, and undo or redo changes. - Safer file workflows: Detect external changes, keep recovery data, preserve optional backups, and verify supported copy or move operations before removing a source. - VFS Library: Organize supported local, cloud, NAS, and remote locations with folders, search, tags, favorites, Recent, and Trash. PERFECT FOR: - CSV and TSV cleanup, review, migration, and handoff - JSON, YAML, TOML, XML, .env, and configuration-file maintenance - Identifiers, codes, phone numbers, dates, and values that must stay literal - Large delimited files that exceed conventional spreadsheet row limits - Value-level XLSX inspection without unsupported formatting claims GETTING STARTED: - Open a supported file from QuickSheet, the system file picker, or a configured location. - Review Import Preview for the detected dialect or structured mapping. - Search, filter, sort, inspect problems, and edit values or formulas. - Turn off Read-Only only when you are ready to change a large or sensitive file. - Save in place to preserve the current format, save a copy in another supported format, or export selected data. PRIVACY & SECURITY: - File contents are processed on-device. - QuickSheet does not provide hosted sync or shared editing. - Cloud and NAS locations are accessed directly with credentials you configure. - Tags, favorites, import profiles, view state, and recovery data are stored outside source files. FREE AND PRO: - Start with a seven-day ad-free trial. - Free keeps the full feature set and may show mobile advertising or a daily desktop support reminder. - QuickSheet Pro removes ads and reminders through a yearly subscription or a one-time lifetime purchase.
