CSV Editor & Converter

Open, edit, and validate CSV files with auto-detected encoding, then export clean data to CSV or JSON

macOSUtilities$9.99v1.1

Working with CSV files means dealing with encoding problems, inconsistent delimiters, and data that needs cleanup before it is usable. CSV Editor & Converter handles the structural work automatically so you can focus on the data.

What it does

Everything you need. Nothing you don't.

🧭
Automatic file detection

Encoding (UTF-8, UTF-16, ASCII, Latin-1, CP1252), delimiter (comma, semicolon, tab, or pipe), and header row are detected on open.

📝
Spreadsheet-style editing

Click any cell or header to edit it inline, with full undo and redo and an unsaved-changes indicator.

✅
Column validation

Columns are typed as string, integer, decimal, boolean, date, email, or URL, and mismatched rows are flagged as warnings you can step through.

🔎
Search and replace

Filter rows by any text, enable case-sensitive matching, and replace exact strings across the whole table in one operation.

📤
CSV and JSON export

Choose encoding, delimiter, and header for CSV — or emit a JSON array with pretty-printing and native typed values.

📊
Column profiling

Select any column header to view a type-distribution summary of that column's data at a glance.
