Convert Base64 to CSV Online

This web utility converts a Base64 encoded string back into its original CSV file format. Simply upload your Base64 encoded data, and the program will do the rest, decoding the data and delivering a CSV file version of your data in no time.

What is Base64?

Base64 is a method of encoding binary data into ASCII characters to facilitate data transfer and storage.

What is CSV?

CSV is an abbreviation for “Comma-Separated Values”. It is a plain text file type that stores tabular data in a delimited text format. Each row and column in a CSV file represent a data record and a field, respectively. In a CSV file, the delimiter is a character that separates individual values inside a row. A comma is the most commonly used delimiter, but other characters such as tab characters and semicolons can also be used.

Here is an example of a CSV file:

Name,Characters,Website
Base64,64,b64encode.com
Base32,32,base32encode.com

What is Base64 Decoding?

Base64 decoding is essentially the operation of converting Base64-encoded data into its corresponding binary format. This process inverts the encoding scheme, translating characters from the 64-character ASCII set into their binary representations. Base64 decoding effectively restores the original data, enabling you to access, interpret, and utilize it as intended.

How Does Base64 Decoding Work?

Here are the steps involved in Base64 decoding:

1. Split the Base64-encoded text into groups of four characters.
2. Convert each group of four characters into a 24-bit integer.
3. Break the 24-bit integer into three 8-bit integers (bytes).
4. Convert each 8-bit integer (byte) back into its corresponding binary value.
5. Combine the three 8-bit integers (bytes) to form the original binary data.
