CSV Viewer

Parse and display CSV data in a table format.

Runs in your browser — your data never leaves your device

First row is header

CSV (Comma-Separated Values) is one of the most common formats for exporting tabular data from spreadsheets, databases, and APIs. This viewer parses, displays, and converts CSV files entirely in your browser so you can inspect and transform data without installing additional software.

How to View CSV Data

Paste CSV text directly into the input area, or switch to the Upload File tab and drag a .csv file into the drop zone. The tool automatically detects column headers and displays the data in a paginated table.

Use the Columns dropdown to show or hide individual columns, and the Download menu to export the data as JSON, XML, TOML, or SQL insert statements. Toggle the First row is header checkbox if your CSV does not include a header row.

Tips for Working with CSV Files

CSV files are plain text, which makes them easy to generate and share, but they have no standard for data types. A value like 00123 may lose its leading zeros when imported into a spreadsheet. Always preview your data after conversion to confirm nothing was lost.

Fields that contain commas, quotes, or newlines should be enclosed in double quotes. If you encounter parsing errors, check for unescaped quotes or inconsistent delimiters (some systems use semicolons instead of commas). This viewer handles standard RFC 4180 escaped quotes automatically.
