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 decodeXlsIO
to get a list of all worksheets. For example to convert all
worksheets in an xls file to comma separated csv:
import Data.List (intercalate)
import Data.Xls (decodeXlsIO)
xlsToCSV :: String -> IO ()
xlsToCSV file = do
worksheets <- decodeXlsIO file
mapM_ (mapM_ (putStrLn . intercalate ",")) worksheets
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.
