Note that older versions of IE do not support HTML5 File API, so the base64 mode
|

is used for testing. On OSX you can get the base64 encoding with:

```bash

$ <target_file base64 | pbcopy

### Note on Streaming Read
|
||||
|
||||
The most common and interesting formats (XLS, XLSX/M, XLSB, ODS) are ultimately
|
||||
ZIP or CFB containers of files. Neither format puts the directory structure at
|
||||
the beginning of the file: ZIP files place the Central Directory records at the
|
||||
end of the logical file, while CFB files can place the FAT structure anywhere in
|
||||
the file! As a result, to properly handle these formats, a streaming function
|
||||
would have to buffer the entire file before commencing. That belies the
|
||||
expectations of streaming, so we do not provide any streaming read API. If you
|
||||
really want to stream, there are node modules like `concat-stream` that will do
|
||||
the buffering for you.
|
||||
|
||||
## Working with the Workbook

||||

||||
The full object format is described later in this README.

### Note on Streaming Read
|
||||
|
||||
The most common and interesting formats (XLS, XLSX/M, XLSB, ODS) are ultimately
|
||||
ZIP or CFB containers of files. Neither format puts the directory structure at
|
||||
the beginning of the file: ZIP files place the Central Directory records at the
|
||||
end of the logical file, while CFB files can place the FAT structure anywhere in
|
||||
the file! As a result, to properly handle these formats, a streaming function
|
||||
would have to buffer the entire file before commencing. That belies the
|
||||
expectations of streaming, so we do not provide any streaming read API. If you
|
||||
really want to stream, there are node modules like `concat-stream` that will do
|
||||
the buffering for you.
