CSV. Done right.

OpenCSV is the fastest way to open, view, and edit CSV files on your phone. No bloated spreadsheet app, no ads, no clutter — just your data, instantly.

OPEN ANY CSV INSTANTLY
Tap a .csv file anywhere on your phone — file manager, email attachment, downloads — and OpenCSV opens it in a clean, scrollable grid in a fraction of a second. Large files load fast thanks to a purpose-built CSV engine.

EDIT EVERY CELL
Tap any cell to edit it inline. Add or delete rows and columns, rename headers, and search across thousands of rows. When you're done, save the file back to your device or to your OpenCSV cloud.

PRIVATE BY DESIGN
Files you open are processed on your device. Nothing is uploaded unless you choose to save a file to your cloud storage. No ads, no data selling — privacy isn't a premium feature.

CLOUD SYNC & SHARING
Save CSVs to your OpenCSV account and they're available on every device — phone, tablet, and at opencsv.io in any browser. Generate a read-only link to share a spreadsheet with anyone; revoke it any time.

WORKS WITH YOUR WORKFLOW

WHO IT'S FOR
Anyone who receives CSV exports and just wants to see and fix the data: small business owners checking order exports, marketers cleaning mailing lists, developers eyeballing data dumps, students working with datasets — without waiting for a heavyweight spreadsheet suite to boot.
