What is CSV Formatter & Viewer?

The CSV Formatter & Viewer is a professional-grade online utility designed for data analysts, developers, and excel users. It provides a secure, client-side environment to parse, validate, and visualize CSV (Comma-Separated Values) files. Unlike simple text editors, this tool offers an interactive grid view, allowing you to sort, filter, and analyze tabular data effortlessly. It fully supports the RFC 4180 standard, handling complex edge cases like multiline fields and escaped quotes. Additionally, it serves as a powerful converter, enabling instant transformation of CSV data into JSON format for web development or API integration.

Key Features

  • Smart Parsing: Automatically detects or allows custom delimiters (comma, tab, pipe, semicolon).
  • Interactive Grid: View data in a sortable, responsive table layout.
  • Data Conversion: Instantly convert CSV to JSON array of objects.
  • Statistics: Real-time count of rows, columns, and total data cells.
  • Validation: Checks for malformed CSV lines and quoting issues.

How to Use

  • 1. Paste your CSV data into the input editor or load a sample.
  • 2. Adjust configuration (Delimiter, Header row, Quote char) if needed.
  • 3. Click 'Format / View' to render the data table.
  • 4. Use 'Export JSON' to get the JSON representation of your data.
