How to Open and Edit a CSV File on iPhone

Short answer: to open and edit a CSV file on an iPhone, use CSV Viewer and Editor. It opens CSVs from Files, the clipboard or a URL, detects the delimiter and header row on its own, lets you edit cells, and compares two files cell by cell. It works offline.

Why CSVs are awkward on a phone

A CSV is plain text with commas, semicolons, tabs or pipes between values. Opened as text it is unreadable, and spreadsheet apps often mangle encoding or require a large import step.

How to open a CSV on iPhone

Install a CSV viewer from the App Store.
Open the file from Files or the share sheet, paste it from the clipboard, or fetch it from a URL.
The app detects the delimiter (comma, semicolon, tab or pipe) and the header row automatically.
Explore it as a sortable table, or switch to the raw view.

What to look for in a CSV app

Automatic delimiter and header detection.
Sortable table view with row search.
Quick stats: row count, column count, empty rows, unique values, and min, max, average and sum for numeric columns.
Cell editing, with add and delete for rows and columns.
Repair of malformed files, such as short rows and unclosed quotes.
A diff of two CSVs, down to the cell level.
Offline operation.

CSV Viewer and Editor includes each of these.
