Why it exists
Plenty of CSV apps on a phone are really viewers wearing a spreadsheet costume: they show you the first few thousand rows, then truncate the file or quietly refuse it. CSV Editor was built the other way round — start from a file that is too big, make it open in seconds, and only then add editing, filters, charts and formulas on top. Even the free version writes back every row.
Edit like a spreadsheet
- Tap to select, tap again to edit — Excel-style on touch.
- Insert, delete, and reorder rows and columns.
- Undo and redo everything.
- Freeze rows and columns so headers stay put while you scroll.
- Select ranges with drag handles, clear whole ranges at once.
Built for big files
- Opens 500,000+ row files without slowing down.
- Background loading with live progress — start reading immediately.
- Smooth flick-scrolling through the whole sheet.
Sort and filter
- Excel-style AutoFilter per column.
- Sort text, numbers, and dates the way Excel does.
- Filtered rows are protected: edits and deletes never touch hidden data.
Charts
- Turn any selection into a chart in two taps.
- Bar, line, and more.
- Save chart images to your photo library or share them.
Formula columns
- Add a computed column that fills down every row, like a spreadsheet formula.
- Reference other columns by name — e.g. [Price] * [Qty].
- Built-in functions: IF, ROUND, ABS, MIN, MAX, CONCAT, UPPER, LOWER, TRIM, LEN, CONTAINS.
- Live preview and inline error checking while you build the formula.
- Formulas save inside the CSV, so results are readable in any app.
Smart format handling
- Auto-detects delimiters, headers, and encodings.
- Opens TSV and other delimited files.
- Re-open with custom parse settings when a file is unusual.
Your file comes back whole
Your files are never truncated: even in the free version, every row of your file is preserved when you save.
Questions
- How large a CSV file can it open?
- Files of 500,000+ rows open without slowing down. Loading happens in the background with live progress, so you can start reading before the whole file has finished.
- Does the free version truncate my file?
- No. Every row of your file is preserved when you save, even in the free version.
- Can I use spreadsheet formulas?
- Yes. Add a computed column that fills down every row and reference other columns by name, such as [Price] * [Qty]. IF, ROUND, ABS, MIN, MAX, CONCAT, UPPER, LOWER, TRIM, LEN and CONTAINS are built in, with live preview and inline error checking. Formulas save inside the CSV, so the results are readable in any app.
- Does it open TSV files and unusual delimiters?
- Yes. Delimiters, headers and encodings are auto-detected, TSV and other delimited files open directly, and you can re-open a file with custom parse settings when it is unusual.
- Is it safe to edit while a filter is applied?
- Yes. Filtered rows are protected — edits and deletes never touch hidden data.
