What is Base64?

Base64 is a binary-to-text encoding scheme that uses 64 characters and a padding symbol (“=”) to convert data into a format that can be stored or transported in a text-only environment.

The Base64 solution is used in many areas, such as web pages, to reduce the number of requests needed by not having to call a new file on the server. It is now also used in various protocols or for sending email attachments.

What is CSV?

A CSV (Comma Separated Values) file is a plain text file that stores data by delimiting entries with commas. These files are frequently used to share information across applications such as databases and contact managers.

Each line of the file normally represents one record, and each record is made up of the same number of fields, which are separated by commas in the CSV file. CSV files are intended to be readily exported and imported into other programs, and the generated data is human-readable and viewable in a text editor or spreadsheet tool.

What is Encoding & Decoding?

Encoding and decoding are two complementary processes that convert data from one format to another.

Encoding is the conversion of data from one format to another, usually to store the data in a more efficient form.

Decoding is the process of converting encoded data back to its original form.

What is a CSV to Base64 Converter?

The CSV to Base64 Converter is a program that converts CSV files into their Base64 encoded text equivalent. This conversion enables CSV files to be encoded using the Base64 algorithm.

How do I use the Online CSV to Base64 Encoder?

  1. First, upload your CSV file.
  2. No need to press a button, just wait until the encoding is complete. For large files, this may take longer.
  3. The Base64 result will automatically appear in the Output field.
  4. If you want, you can copy the result using the Copy button.

Is it secure to use your CSV to Base64 Converter?

The application is designed in such a way that it runs exclusively on the client side. This means that all conversions take place within the user’s browser and no data is sent to the servers about your conversion. Using this method assures the confidentiality and control of user data during the conversion process.
