`xls` is a Haskell library to parse Microsoft Excel spreadsheet files. It
parses the xls file format (extension `.xls`) more specifically known as
`BIFF/Excel 97-2004`.

It can be useful for mining data from old Microsoft Excel spreadsheets.

## API
Use `decodeXls` to get a streaming Conduit. For example to convert an
xls file to comma separated csv:

```haskell
xlsToCSV :: String -> IO ()
xlsToCSV file =
      runResourceT
    $ decodeXls file
    $$ CL.mapM_ (liftIO . putStrLn . intercalate ",")
```

An `xls2csv` utility is shipped with the package.
See the haddock documentation for API details.

## Under the hood
The library is based on the C library libxls, see
[sourceforge](https://sourceforge.net/projects/libxls/) or
[github](https://github.com/svn2github/libxls).
