About CSV URL Decoder

This tool decodes URL-encoded CSV data back to its original readable format. URL encoding (also called percent encoding) is commonly used when CSV data is transmitted through URLs, web forms, or API requests.

Common URL-encoded characters in CSV:

  • %2C → comma (,)
  • %0A → newline
  • %0D → carriage return
  • %20 → space
  • %22 → double quote (")

Need to work with different CSV delimiters? Try our CSV Delimiter Converter to switch between comma, semicolon, tab, and other separators.

All processing happens entirely in your browser – no data is sent to any server. Your CSV data remains completely private.

Frequently Asked Questions (FAQ)

What is URL-encoded CSV data?
URL-encoded CSV data is comma-separated values where special characters like commas, newlines, and spaces are converted to percent-encoded format (e.g., %2C for comma, %0A for newline). This encoding is commonly used when CSV data is passed through URLs or web forms.
How does URL encoding work for CSV?
URL encoding replaces unsafe characters with a percent sign (%) followed by their hexadecimal ASCII code. For CSV data: commas become %2C, newlines become %0A, spaces become %20, and quotes become %22. This tool reverses that process.
Is my data processed securely?
Yes! All decoding happens entirely in your browser using JavaScript. No data is sent to any server. Your CSV data remains private and secure on your device.
What if my CSV contains special characters?
This tool handles all standard URL-encoded characters including international characters (UTF-8), special symbols, and control characters. If decoding fails, ensure your input is properly URL-encoded.
Can I decode CSV data from a URL query string?
Yes! If you have CSV data embedded in a URL query parameter, simply paste the encoded portion into this tool. For more URL handling, check out our URL Encoder/Decoder tool.
How can I convert the decoded CSV to other formats?
After decoding your CSV, you can use our CSV to JSON Converter to transform it to JSON format, or use the CSV Viewer to visualize the data in a table.
