Import and export JSON-Base64 (*.jb64) files.
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.
The JSON-Base64 file format:
Supports multiple flat field types (booleans, integers, floating-point, strings, etc).
Preserves Unicode character sequences.
The first line contains a header record that defines each column name and its type.
Each line contains exactly one record.
Can be processed as a stream.
Optional hash support for detecting accidental data corruption.
Very easy to implement in most modern programming languages.
Unencumbered by patents and is public domain.
It's not glamorous, but JSON-Base64 solves the real-world, age-old problem of data conveyance. That is, moving data between two disparate software systems.
