Automation Workshop includes the Base64 Decode Action that converts Base64-encoded data back into readable text. It supports both Standard Base64 and the URL-safe Base64URL format, with automatic format detection available when the source type is not known in advance.
Encoded input can be entered directly or supplied dynamically through Variable Wizard. Additional options control the output character set, invalid character handling, missing padding recovery, and optional result storage for use in subsequent workflow steps.
Features & highlights
- Standard Base64 and Base64URL—Decode conventional Base64 data or URL-safe values used by web applications, APIs, tokens, and filenames.
- Automatic format detection—Let the Action determine whether the input uses the Standard Base64 or Base64URL alphabet.
- Multiple output character sets—Convert decoded bytes to UTF-8, ASCII, or ISO-8859-1 text.
- Flexible input validation—Fail on unexpected characters, ignore whitespace, or discard all characters outside the selected Base64 alphabet.
- Automatic padding recovery—Restore missing trailing
=characters when the encoded input can be completed correctly. - Reusable decoded output—Access the result through Variable Wizard or store it in an existing variable for later Actions.
Usage examples
- Decode Base64 or Base64URL values received from web services, APIs, forms, and connected systems.
- Restore encoded JSON payloads, configuration values, identifiers, or message content for further processing.
- Decode values that contain line breaks, spaces, or other formatting characters introduced during transport.
- Process unpadded Base64URL strings commonly used in URLs, web tokens, and API parameters.
- Convert dynamically received encoded data and pass the decoded result to file, email, web, scripting, or validation Actions.
