What Is a CSV to Base64 Converter?

This tool converts CSV (Comma Separated Values) data into the base64 encoding format. While CSV files are great for storing and sharing data in a human-readable format, they can be cumbersome to embed in HTML documents, use in tests, or store in variables (when programming). Base64 encoding allows CSV data to be used in all these cases easily as it converts newlines, quotes, and special symbols that appear in CSV into alphabet letters. The base64 output can have a long continuous sequence of characters or it can be divided into several chunks of a certain length. The number of characters per chunk can be specified in the options. When the base64 output is chunked, it's more convenient to manage as the lines aren't that long and certain protocols, such as MIME, require that base64 data is split into chunks of 76 characters. You can also turn the output into a valid data URI, prefixed with "data:text/csv;base64,". If you already have data encoded in base64 and want to decode it, you can use our reverse tool Convert Base64 to CSV. Csv-abulous!

Base64-encode CSV Countries Data

In this example, we encode a CSV file containing information about countries, their official languages, and currencies into the base64 format. The resulting base64 output is a single continuous string without line breaks, providing a new representation of the original CSV data.

country,language,currency France,French,Euro Brazil,Portuguese,Real Japan,Japanese,Yen India,Hindi,Rupee Germany,German,Euro

Chunked Base64 CSV

In this example, we base64-encode a three-column CSV dataset with detailed information about music genres, their origins, and key instruments. To make the encoded data easier to share, we activate the option to split it into chunks, with each line containing 20 characters.

genre,origin,key_instrument Rock,1950s,Electric guitar Hip-Hop,1970s,Turntable EDM,1980s,Synthesizer

Create a Data URL CSV

This example transforms CSV data containing details about artists, songs, genres, streaming statistics, and release years into a compact base64 encoding. By activating the data URL option, the output data gets the prefix "data:text/csv;base64," making it suitable for direct embedding into HTML documents and programs that require valid data URLs.
