OneOpen vs QuickSheet

OneOpen opens the files you receive from Files, Mail, and other apps. Everyday viewing stays free and local. FREE FILE VIEWING Open HTML and ZIP website packages as isolated mini apps. Read Markdown, PDF, Office and iWork documents, common images, audio, video, JSON, YAML, XML, CSV, source code, and text. Search and edit common text formats in a separate copy; your original remains untouched. Recents and widgets put your files within reach. ADVANCED FORMATS Advanced Access unlocks specialized previews: 3D models, RAW and design images, fonts, certificates, property lists, email, subtitles, contacts, calendars, specialist archives and data, CAD and circuit files, and the binary inspector. Choose an annual subscription or a one-time lifetime purchase; both unlock the same features. PRIVACY AND HTML SAFETY OneOpen has no account, ads, analytics, or document uploads. Non-HTML previews stay offline. Imported HTML and ZIP websites may run JavaScript and connect to HTTPS/WSS servers in an isolated WebKit store. Switch to offline mode or Safe Preview at any time; HTTP, embedded frames, unexpected navigation, and access to other local files remain blocked. Webpage code may contact third-party servers when you allow network access. Terms of Use: https://oneapps.studio/terms Privacy Policy: https://oneapps.studio/privacy

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.
