input CSV, including those
typically not considered
as special in URLs (such
as letters and digits).

What Is a CSV URL-encoder?

This tool converts Comma Separated Values (CSV) data to URL-encoding (also known as URL-escaping or percent-encoding). URL-encoding allows CSV files to be used in URLs as parts of the path and as GET parameters. As URLs can handle only a limited set of characters, several special characters such as commas (,), semicolons (;), and spaces can confuse web browsers and servers if they are included directly in the URL. URL-encoding solves this issue by transforming these special characters into a format understandable by all browsers. This encoding format essentially replaces all special characters in your CSV with specific hex codes that are prefixed with the percent symbol and look like this "%XX", where "XX" is the hex character code (it can be from "00" to "FF"). This tool also offers you several customization options for the encoding process. By default, it encodes only special characters, but you can enable the "Escape All Characters" option to URL-encode all input characters in the CSV file. You can also activate the "Line-by-line" option that preserves the original multiline format of your CSV without encoding newline characters. Additionally, you can choose whether the encoded hex codes will be displayed in uppercase or lowercase letters. For the reverse operation, you can use our URL-decode CSV tool. Csv-abulous!


CSV URL-encoder Examples

URL-escape CSV with Chess Openings

In this example, we load a CSV file containing information about various chess openings and their associated winning chances. Since this data contains many special characters, such as commas (,), spaces ( ), percent signs (%), and newline characters, it cannot be used directly in a URL. Therefore, we apply URL encoding to the CSV, replacing the listed special characters with lowercase hexadecimal codes.

Percent-encode CSV Recipes

In this example, we convert a CSV file containing recipe information (including recipe names, ingredients, and quantities) into percent-encoded data. We enable the "Encode All Characters" option and replace not only the special characters but also all other input characters as well. Additionally, we enable the "Use Uppercase Letters" option to make the percent-encoded data uppercase.

recipe,ingredient,quantity Pasta Carbonara,Spaghetti,200g Caesar Salad,Romaine Lettuce,150g Chocolate Cake,Flour,300g
%72%65%63%69%70%65%2C%69%6E%67%72%65%64%69%65%6E%74%2C%71%75%61%6E%74%69%74%79%0A%50%61%73%74%61%20%43%61%72%62%6F%6E%61%72%61%2C%53%70%61%67%68%65%74%74%69%2C%32%30%30%67%0A%43%61%65%73%61%72%20%53%61%6C%61%64%2C%52%6F%6D%61%69%6E%65%20%4C%65%74%74%75%63%65%2C%31%35%30%67%0A%43%68%6F%63%6F%6C%61%74%65%20%43%61%6B%65%2C%46%6C%6F%75%72%2C%33%30%30%67

Line-by-line Mode

This example converts CSV to URL encoding using the line-by-line mode. The input CSV contains data about various gemstones, their colors, and their hardness rated from 1 to 10 on the Mohs scale. To clearly separate each data record for each gemstone, we enable the multi-line mode, which URL-encodes each record separately. As a result, we get the same 5 lines of data, only with special characters converted to hex codes on each line.
