Haskell xls Parsing

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:

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.
