are not processed by any of the core library functions. By default these cells
will not be generated; the parser `sheetStubs` option must be set to `true`.
#### Dates
By default, Excel stores dates as numbers with a format code that specifies date
processing. For example, the date `19-Feb-17` is stored as the number `42785`
with a number format of `d-mmm-yy`. The `SSF` module understands number formats
and performs the appropriate conversion.
XLSX also supports a special date type `d` where the data is an ISO 8601 date
string. The formatter converts the date back to a number.
The default behavior for all parsers is to generate number cells. Setting
`cellDates` to true will force the generators to store dates.
### Worksheet Object
Each key that does not start with `!` maps to a cell (using `A-1` notation)

use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the

within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.

liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only

@ -37,3 +37,16 @@ Type `z` represents blank stub cells. These do not have any data or type, and
are not processed by any of the core library functions. By default these cells
will not be generated; the parser `sheetStubs` option must be set to `true`.
#### Dates
By default, Excel stores dates as numbers with a format code that specifies date
processing. For example, the date `19-Feb-17` is stored as the number `42785`
with a number format of `d-mmm-yy`. The `SSF` module understands number formats
and performs the appropriate conversion.
XLSX also supports a special date type `d` where the data is an ISO 8601 date
string. The formatter converts the date back to a number.
The default behavior for all parsers is to generate number cells. Setting
`cellDates` to true will force the generators to store dates.
