CodeBeautifyCSV Formatter & Beautifier
Format CSV online into an aligned, readable table view, or minify it back into compact standard CSV. Auto-detect delimiters and handle quoted fields correctly.
What is CSV?
CSV (Comma-Separated Values) is a plain-text format for tabular data, where each line is a row and fields within a row are separated by a delimiter — usually a comma. Its simplicity makes it the most common interchange format for spreadsheets, database exports, and data pipelines, but that same simplicity means there's no single strict standard: quoting rules, delimiters, and encoding can vary between the tools that produce it.
Why view CSV as an aligned table?
Raw CSV is hard to read directly — columns of different widths run together with nothing to visually separate them. This tool pads every column to the width of its longest value and lines them up with a separator, so you can scan rows and columns the way you would in a spreadsheet, without leaving your text editor or terminal.
Example
| Raw CSV | Aligned view |
|---|---|
name,age,city | name | age | city |
Frequently asked questions
How do I format CSV online?
Paste your CSV data into the input box and click Beautify. The formatter aligns every column into a readable table view instantly.
How do I beautify a CSV file?
Beautifying CSV pads each column to match its widest value so rows line up like a spreadsheet. Click Beautify and the beautifier handles alignment automatically, even with quoted fields.
Why does my CSV need quotes around some fields?
A field must be quoted if it contains the delimiter itself, a double quote, or a line break — otherwise a parser couldn't tell where that field ends. A quote character inside a quoted field is escaped by doubling it ("").
Does the aligned table view change my data?
No — padding with spaces for alignment is purely visual. Use Minify to convert back to a compact, standard CSV file with the padding removed.
