## Writing Options
|
|
|
|
|
|
|
|
|
|
The exported `write` and `writeFile` functions accept an options argument:
|
|
|
|
|
|
|
|
|
|
| Option Name | Default | Description |
|
|
|
|
|
| :---------- | -------: | :-------------------------------------------------- |
|
|
|
|
|
| type | | Output data encoding (see Output Type below) |
|
|
|
|
|
| cellDates | `false` | Store dates as type `d` (default is `n`) |
|
|
|
|
|
| bookSST | `false` | Generate Shared String Table ** |
|
|
|
|
|
| bookType | `"xlsx"` | Type of Workbook (see below for supported formats) |
|
|
|
|
|
| sheet | `""` | Name of Worksheet for single-sheet formats ** |
|
|
|
|
|
| compression | `false` | Use ZIP compression for ZIP-based formats ** |
|
|
|
|
|
|
|
|
|
|
- `bookSST` is slower and more memory intensive, but has better compatibility
|
|
|
|
|
with older versions of iOS Numbers

- The raw data is the only thing guaranteed to be saved. Features not described
|
|
|
|
|
in this README may not be serialized.

|
|
|
- `cellDates` only applies to XLSX output and is not guaranteed to work with
|
|
|
|
|
third-party readers. Excel itself does not usually write cells with type `d`
|
|
|
|
|
so non-Excel tools may ignore the data or blow up in the presence of dates.
|
|
|
|
|
|
|
|
|
|
### Supported Output Formats
|
|
|
|
|
|
|
|
|
|
For broad compatibility with third-party tools, this library supports many
|
|
|
|
|
output formats. The specific file type is controlled with `bookType` option:
|
|
|
|
|
|
|
|
|
|
| bookType | file ext | container | sheets | Description |
|
|
|
|
|
| :------- | -------: | :-------: | :----- |:--------------------------------- |
|
|
|
|
|
| `xlsx` | `.xlsx` | ZIP | multi | Excel 2007+ XML Format |
|
|
|
|
|
| `xlsm` | `.xlsm` | ZIP | multi | Excel 2007+ Macro XML Format |
|
|
|
|
|
| `xlsb` | `.xlsb` | ZIP | multi | Excel 2007+ Binary Format |
|
|
|
|
|
| `ods` | `.ods` | ZIP | multi | OpenDocument Spreadsheet |
|
|
|
|
|
| `biff2` | `.xls` | none | single | Excel 2.0 Worksheet format |
|
|
|
|
|
| `fods` | `.fods` | none | multi | Flat OpenDocument Spreadsheet |
|
|
|
|
|
| `csv` | `.csv` | none | single | Comma Separated Values |
|
|
|
|
|
|
|
|
|
|
- `compression` only applies to formats with ZIP containers.
|
|
|
|
|
- Formats that only support a single sheet require a `sheet` option specifying
|
|
|
|
|
the worksheet. If the string is empty, the first worksheet is used.
|
|
|
|
|
|
|
|
|
|
### Output Type
|
|
|
|
|
|
|
|
|
|
The `type` argument for `write` mirrors the `type` argument for `read`:
|
|
|
|
|
|
|
|
|
|
| `type` | output |
|
|
|
|
|
|------------|-----------------------------------------------------------------|
|
|
|
|
|
| `"base64"` | string: base64 encoding of the file |
|
|
|
|
|
| `"binary"` | string: binary string (`n`-th byte is `data.charCodeAt(n)`) |
|
|
|
|
|
| `"buffer"` | nodejs Buffer |
|
|
|
|
|
| `"file"` | string: name of file to be written (nodejs only) |
|
