The `MS-XLSB` specification covers the basics of the file format, and other
specifications expand on serialization of features like properties.
### OpenDocument Spreadsheet (ODS/FODS)
### Delimiter-Separated Values (CSV/TXT)
Excel CSV deviates from RFC4180 in a number of important ways. The generated
CSV files should generally work in Excel although they may not work in RFC4180
compatible readers. The parser should generally understand Excel CSV.
Excel TXT uses tab as the delimiter and codepage 1200.
### Other Workbook Formats
Support for other formats is generally far XLS/XLSB/XLSX support, due in large
part to a lack of publicly available documentation. Test files were produced in
the respective apps and compared to their XLS exports to determine structure.
The main focus is data extraction.
#### Lotus 1-2-3 (WKS/WK1/WK2/WK3/WK4/123)
The Lotus formats consist of binary records similar to the BIFF structure. Lotus
did release a whitepaper decades ago covering the original WK1 format. Other
features were deduced by producing files and comparing to Excel support.
#### Quattro Pro (WQ1/WQ2/WB1/WB2/WB3/QPW)
The Quattro Pro formats use binary records in the same way as BIFF and Lotus.
Some of the newer formats (namely WB3 and QPW) use a CFB enclosure just like
BIFF8 XLS.
#### OpenDocument Spreadsheet (ODS/FODS)
ODS is an XML-in-ZIP format akin to XLSX while FODS is an XML format akin to
SpreadsheetML. Both are detailed in the OASIS standard, but tools like LO/OO

### OpenDocument Spreadsheet (ODS/FODS)
### Delimiter-Separated Values (CSV/TXT)
Excel CSV deviates from RFC4180 in a number of important ways. The generated
CSV files should generally work in Excel although they may not work in RFC4180
compatible readers. The parser should generally understand Excel CSV.
Excel TXT uses tab as the delimiter and codepage 1200.
### Other Workbook Formats
Support for other formats is generally far XLS/XLSB/XLSX support, due in large
part to a lack of publicly available documentation. Test files were produced in
the respective apps and compared to their XLS exports to determine structure.
The main focus is data extraction.
#### Lotus 1-2-3 (WKS/WK1/WK2/WK3/WK4/123)
The Lotus formats consist of binary records similar to the BIFF structure. Lotus
did release a whitepaper decades ago covering the original WK1 format. Other
features were deduced by producing files and comparing to Excel support.
#### Quattro Pro (WQ1/WQ2/WB1/WB2/WB3/QPW)
The Quattro Pro formats use binary records in the same way as BIFF and Lotus.
Some of the newer formats (namely WB3 and QPW) use a CFB enclosure just like
BIFF8 XLS.

SpreadsheetML. Both are detailed in the OASIS standard, but tools like LO/OO
