## Interface
|
||
|
|
|
||
|
|
`XLSX` is the exposed variable in the browser and the exported node variable
|
||
|
|
|
||
|
|
`XLSX.version` is the version of the library (added by the build script).
|
||
|
|
|
||
|
|
`XLSX.SSF` is an embedded version of the [format library](https://github.com/SheetJS/ssf).
|
||
|
|
|
||
|
|
### Parsing functions
|
||
|
|
|
||
|
|
`XLSX.read(data, read_opts)` attempts to parse `data`.
|
||
|
|
|
||
|
|
`XLSX.readFile(filename, read_opts)` attempts to read `filename` and parse.
|
||
|
|
|
||
|
|
Parse options are described in the [Parsing Options](#parsing-options) section.
|
||
|
|
|
||
|
|
### Writing functions
|
||
|
|
|
||
|
|
`XLSX.write(wb, write_opts)` attempts to write the workbook `wb`
|
||
|
|
|
||
|
|
`XLSX.writeFile(wb, filename, write_opts)` attempts to write `wb` to `filename`.
|
||
|
|
In browser-based environments, it will attempt to force a client-side download.
|
||
|
|
|
||
|
|
`XLSX.writeFileAsync(filename, wb, o, cb)` attempts to write `wb` to `filename`.
|
||
|
|
If `o` is omitted, the writer will use the third argument as the callback.
|
||
|
|
|
||
|
|
`XLSX.stream` contains a set of streaming write functions.
|
||
|
|
|
||
|
|
Write options are described in the [Writing Options](#writing-options) section.
