csv url-decoder

world's simplest csv tool

Free online URL-encoded CSV to URL-decoded CSV converter. Just upload your URL-encoded CSV in the form below and it will automatically get URL-decoded. You can URL-decode CSV files line-by-line or as a single large blob. Created by programmers from team Browserling.

What is a csv url-decoder?

This tool converts CSV files that were previously URL-escaped back into the original readable CSV format. URL escaping is a method for using special characters, such as spaces, commas, and semicolons in web addresses (URLs). These characters are replaced with a specific code format, which is the percent sign followed by two hexadecimal digits. For example, spaces get replaced with "%20" (because the ASCII code of a space character is 0x20 in hex), commas get replaced with "%2c" (because the comma's ASCII code is 0x2c in hex), and semicolons get replaced with "%3b" (because semicolon's ASCI code is 0x3b in hex). This conversion ensures proper interpretation of these characters when they are transmitted as part of a web address in its path or GET arguments. However, if you want to read or edit data stored in a URL-escaped CSV file, it's necessary to decode these special characters back to the original characters. In this program, you can do exactly that and obtain regular, human-readable comma-separated data that you can analyze and edit. If you need to perform the reverse operation and URL-escape a CSV file, you can use our URL-escape CSV tool. Neat fact: because of this percent sign, the encoding is known as percent-encoding. Csv-abulous!

URL Unescape CSV Data

In this example, we URL-unescape a CSV file containing singular and plural forms of invariable nouns (nouns that have the singular and plural forms equal). The input is URL-escaped, meaning special characters like spaces, commas, and newlines are replaced with specific percent-encoded hex values. After decoding these symbols, we obtain a regular comma-separated CSV that is easy to view, edit, analyze, and import in spreadsheet software.

singular%2Cplural%0Asheep%2Csheep%0Adeer%2Cdeer%0Afish%2Cfish%0Amoose%2Cmoose%0Ashrimp%2Cshrimp
singular,plural sheep,sheep deer,deer fish,fish moose,moose shrimp,shrimp

Decode a Multiline CSV

In this example, we use our tool to decode a CSV list containing information about cities, their iconic landmarks, and the annual number of visitors (in millions). The input data has an unconventional format, consisting of a URL-encoded line per CSV record. This format makes it easy to copy and paste individual lines to URL addresses. Despite this multi-line encoding, the tool successfully decodes the data, producing a clear CSV that can be used in further processing.

city%2cattraction%2cvisitors%20(millions) Paris%2cEiffel%20Tower%2c7 Rio%20de%20Janeiro%2cChrist%20the%20Redeemer%2c2 Beijing%2cGreat%20Wall%20of%20China%2c10 Sydney%2cSydney%20Opera%20House%2c10 New%20York%2cStatue%20of%20Liberty%2c4

Fully Encoded Data

In this example, we're working with a completely URL-encoded CSV file. Even regular text characters, including letters and numbers, are percent-encoded. We successfully decode this file and obtain a CSV containing information about various technology companies, their founding years, and their headquarters.
