This module provides a function for reading .xlsx files

Documentation

toXlsx :: ByteString -> Xlsx

Reads Xlsx from raw data (lazy bytestring)

toXlsxEither :: ByteString -> Parser Xlsx

Reads Xlsx from raw data (lazy bytestring), failing with Left on parse error

toXlsxFast :: ByteString -> Xlsx

Reads Xlsx from raw data (lazy bytestring) using xeno library using some "cheating":

• not doing 100% xml validation
• replacing only predefined entities and Unicode character references (without checking codepoint validity)
• almost not using XML namespaces

toXlsxEitherFast :: ByteString -> Parser Xlsx

Fast parsing with Left on parse error, see toXlsxFast
