What Convert CSV to Base64 can do:

Convert CSV to Base64 turns any CSV file into a Base64-encoded string that you can use in scripts, URLs, APIs, or data URIs. It works entirely in the browser with no upload required. You can import files, paste data, and choose whether to strip line breaks from the output all with immediate feedback and export-ready results. It’s the fastest way to get an encoded CSV string for embedding or secure transfer.

Example:

Input CSV:

Name,Age,Location
Alice,30,New York
Bob,27,London

With “Strip newlines” enabled: the Base64 string becomes one continuous line.

Common Use Cases:

Use it to embed CSV content in HTML or JavaScript, send compact data in URLs or headers, or prepare CSV for upload where only Base64 input is accepted. It’s useful for devs, analysts, or anyone dealing with file-to-string conversions for APIs, web apps, or CLI tools.

Useful Tools & Suggestions:

After encoding, use Base64 Decoder if you ever need to double-check or revert the data. And before you start, Compress a CSV File can help shrink the size so the final Base64 string isn’t massive.
