OmniFile Studio opens the technical files other apps can't — instantly, privately, right on your iPhone and iPad.
An Excel sheet from a colleague, a JSON export, a saved email, a log from a server, a GPX from a hike, a SQLite database from a project: open or share it and see what's inside. Real tables, real maps, rendered Markdown, structured config. No laptop, no upload, no account.
DATA FILES, AS TABLES
• Excel workbooks (.xlsx) — every sheet as a table, dates and numbers intact
• CSV and TSV — comma, semicolon, pipe or tab separated, header detection, any encoding
• JSON Lines / NDJSON — one record per line, keys become columns
• Apache Arrow and Feather v2 — tables from pandas, Polars and R
• JSON — browse as a collapsible tree, or as a table when it's a list of records
• Every table gets search across all columns, sorting, column types and fast paging
EMAILS & XML
• Saved emails (.eml) — subject, sender, recipients, the message as text or HTML, attachment list
• XML — any feed, export or config as a collapsible tree; lists of records become a table
TEXT & CONFIG, STRUCTURED
• Markdown — headings, lists, task lists, tables, quotes, code blocks and an outline
• YAML and TOML — Docker Compose, GitHub Actions, pyproject, Cargo… as a tree
• INI, .conf, .cfg and .env — sections and keys, searchable
• Log files — errors, warnings, info and debug, filtered and searchable
• SQL scripts — statement by statement: tables, indexes, views, inserts
• SRT and WebVTT subtitles as a timed cue list
• Line-numbered, highlighted Source view for every text file
MAPS FOR YOUR TRACKS & SHAPES
• GPX tracks, routes and waypoints
• FIT activities and courses from Garmin, Wahoo, Coros, Zwift and other devices
• KML and KMZ placemarks, paths and polygons with their colours and folders
• GeoJSON and GeoPackage layers with every attribute
• Apple Maps: Standard, Satellite, Hybrid, 3D terrain
EVERY STAT FROM YOUR RIDE, RUN OR HIKE
• Distance, elapsed and moving time, pace and speed, climb and descent
• Elevation, speed and heart-rate charts, per-km or per-mile splits, cadence and power from FIT
SQLITE DATABASES IN YOUR POCKET
• Every table and view with row counts, fast paging, search and sort
• Full schema: column types, keys, foreign-key relationships, indexes and triggers
• Core Data stores by entity name — always read-only
WORKS WHERE YOUR FILES ARE
• Quick Look: tap GeoJSON, KMZ, GeoPackage, FIT, SQLite, JSON Lines, Arrow, email, Markdown (.markdown), YAML, TOML, config, SQL and SRT files in Files, Mail or Messages
• Quick View: from any share sheet — Files, Mail, WhatsApp, Safari, AirDrop — preview any supported file without leaving the app
• Note: iOS previews Excel, CSV, JSON, XML, .md, .log and .vtt itself when tapped in Files. For those, use the share sheet → Quick View, or Open in OmniFile Studio
• Open in OmniFile Studio for the full viewer, recents and pins
• Switch any file type off in Settings to keep the system preview instead
