Documentation

toXlsx :: ByteString -> Xlsx Source #

Reads Xlsx from raw data (lazy bytestring)

toXlsxEither :: ByteString -> Parser Xlsx Source #

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

toXlsxFast :: ByteString -> Xlsx Source #

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 Source #

Fast parsing with Left on parse error, see toXlsxFast

data ParseError Source #

Constructors

InvalidZipArchive String
