Open CSV — Viewer & Editor

Spreadsheet view for CSV — open, edit, sort, filter. No account needed.

CSV Viewer & Editor lets you open, view, and edit CSV files right on your phone — even large or broken ones. Whether you're a data analyst, developer, student, or business professional, this app makes working with CSV data effortless.

💾 SAVES YOUR FILE THE WAY IT FOUND IT
• Line endings are preserved — a CRLF file stays CRLF, an LF file stays LF
• The UTF-8 byte order mark is kept, so spreadsheets still read your accents and Cyrillic correctly
• A trailing newline stays exactly as it was — clean diffs in Git, no phantom changes
• Editing changes the data in your file, not its encoding

🔧 OPENS CSVs THAT REFUSE TO OPEN
• Repairs broken or malformed CSV automatically so it opens instead of failing
• Auto-detects the delimiter — comma, tab, semicolon, or pipe (PSV/TSV)
• Large-file mode pages through very big exports instead of running out of memory
• Tells you plainly when a file is too big to load in full — never silently drops rows
• Reads only the file you pick — no "full storage access" demand, fully offline

📊 POWERFUL TABLE VIEW

✏️ FULL EDITING
