## Unreleased
* XLS legacy `!range` field removed
## 0.9.6 (2017-03-25)
* `sheet_to_json` now passes `null` values when `raw` is set to `true`
* `sheet_to_json` treats `null` stub cells as values in conjunction with `raw`

### Chartsheet Object
Chartsheets are represented as standard worksheets. They are distinguished with
the `!type` property set to `"chart"`.
The underlying data and `!ref` refer to the cached data in the chartsheet.
### Workbook Object
`workbook.SheetNames` is an ordered list of the sheets in the workbook

- `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. Formulae, formatting,
and other niceties may not be serialized (pending CSF standardization)
- 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.

### Chartsheet Object
Chartsheets are represented as standard worksheets. They are distinguished with
the `!type` property set to `"chart"`.
The underlying data and `!ref` refer to the cached data in the chartsheet.

@ -13,8 +13,8 @@ The exported `write` and `writeFile` functions accept an options argument:
- `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. Formulae, formatting,
and other niceties may not be serialized (pending CSF standardization)
- 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.
