JSON-Base64 import/export


Imports and exports files in the JSON-Base64 (*.jb64) file format.

This Excel task pane application imports and exports files stored in the JSON-Base64 (*.jb64) file format.

The JSON-Base64 file format, aka JB64, was invented for performing clean data transfers of database records and spreadsheet values across a wide variety of Internet hosts, software programs, and programming languages. JB64 is encoded in a stream-ready format, follows a clearly defined specification, and the file format and reference implementations are public domain.

JB64 (.jb64) is a serious replacement for the aging CSV (.csv) file format. With JSON-Base64, applications that support table-like data (i.e. rows and columns) can send data to each other and encounter far fewer issues that require manual user intervention or custom-built software to handle.
