::xls2dsv::



tool: D30: [description]
  xls2dsv parses the contents of excel (.xls) files and saves
  them as delimiter-separated values (DSV). It currently
  supports BIFF8 (97 - 2007) excel files as input, and can
  output pure ASCII (no extended ASCII ), UTF-16BE or UTF-8
  encoded files. It also supports user defined parameters for
  the DSV output. It outputs one file for every worksheet on
  the excel file (workbook), naming them as follows,
  "[input filename - suffix]_[worksheet name].[suffix]"



tool: D29: [options]

1) -help, displays this message

2) encoding, choose one of the following
   a) -utf8, for UTF-8
   b) -utf16, for UTF-16BE, no BOM prepended
   c) -ascii='r', to replace characters beyond U+007F
         with 'r' ASCII character (ex. -ascii=?, -ascii=x3f)

3) delimiter, choose one of the following
   a) -csv, to output comma-delimited files, using quotation
         marks ('"', 0x22) as text delimiter
   b) -tsv, to output tab-delimited files
   c) -dsv='D','T','E', to explicitly specify the delimiter 'D',
         the text delimiter 'C', and the first letter of file
         extension to use 'E' (ex. -dsv=?,!,q, -dsv=x3f,x22,q);
         note that ',' or x63 and x09 are reserved delimiters,
         and 'c' and 't' are reserved file extensions

4) compact, choose one of the following
   a) -compact=0, to preserve the original dimension
   b) -compact=1, to discard empty rows and columns
         after non-empty ones
   c) -compact=2, to discard empty rows and columns
         before and after non-empty ones
   d) -compact=3, to discard all empty cells

5) -crlf, inserts CR+LF as newline; otherwise LF only

6) -enclose, encloses all values with the
      delimiter-collision-avoidance character

7) [source file or directory]

8) [destination directory]



tool: D23: [default]
encoding:   -utf8
delimiter:  -csv
compact:    -compact=0



tool: D34: [sample usage]

a) "./xls2dsv"
    will convert all excel files in the working directory into
    comma-delimited, UTF-8-encoded files, preserving the original
    dimension of the excel files, and saving each individual
    worksheets of every file with .csv file extension

b) ".xls2dsv -ascii=$ -dsv=?,x3d,q input.xls output -compact=3"
    will convert the "input.xls" file into question-mark-delimited, pure-
    ascii-encoded (replacing non-ASCII characters with '$' sign) files,
    ignoring all empty cells and enclosing all values containing the
    delimiter character '?', the new line character '\n', and the text
    delimiter character '"' with the text delimiter character '"',
    and saving all worksheets of the file into existing "output"
    directory with ".qsv" file extension

c) "./xls2dsv input"
    will have the same effect as a) except that input files will
    come from the "input" directory and all output will be saved
    into the same "input" directory
