If you "cat" an .xls file, you will notice that unix understand it as binary file, and you won't see relevant content. Instead, you can rely on "comma separated value format" and alter such file. Otherwise, you can use Excel's macros, thus putting yourself in need of writing on Visual basic.

NAME
ssconvert - a command line spreadsheet format converter SYNOPSIS
ssconvert [OPTIONS] infile outfile ssconvert [OPTIONS] --merge-to outfile infile1 infile2 ... DESCRIPTION
ssconvert is a command line utility to convert spreadsheet files between various spreadsheet file formats. It is a companion utility to Gnumeric, the powerful spreadsheet program created by the GNOME project. ssconvert accepts either file names or URIs as infile outfile. The special URIs fd://0 and fd://1 can be used for standard input and stan- dard output respectively. OPTIONS
This program follows the usual GNU command line syntax, with single letter options starting with a single dash (`-') and longer options starting with two dashes (`--'). Main options --recalc Recalculate all cells before writing the result. --list-exporters List the available exporters (file formats that can be written). -T, --export-type=ID Specify which exporter to use; see below for a list. This is only necessary when the right format does not follow from the output file name. -O, --export-options=optionsstring Specify parameters for the chosen exporter. optionsstring is a list of parameter=value pairs, separated by spaces. The parameter names and values allowed are specific to the exporter and are documented below. Multiple parameters can be specified --list-importers List the available importers (file formats that can be read). -I, --import-type=ID Specify which importer to use; see below for a list. This is only necessary when the right format does not follow from the input file name. -E, --import-encoding=STRING Specify an encoding for imported content. -M, --merge-to=FILENAME Merge a collection of workbooks into one. Sheet size will expand to the largest in all the workbooks. Names in the scope of indi- vidual workbooks will end up in the scope of the merged workbook. The merge will be aborted if there are name conflicts. -S, --export-file-per-sheet Export a file for each sheet if the exporter only supports one sheet at a time. The output filename is treated as a template in which sheet number is substituted for %n and/or sheet name is substituted for %s. If there are not substitutions, a default of ".%s" is added. Help options -v, --version Display ssconvert's version. -h, --help, --usage Display a brief usage message. --help-all Show all help options. --help-libspreadsheet Show Gnumeric options. Path options -L, --lib-dir=STRING Set the root library directory. -D, --data-dir=STRING Adjust the root data directory. LIST OF IMPORTER

OPTIONS FOR THE CONFIGURABLE TEXT (*.txt) EXPORTER sheet Name of the workbook sheet to operate on. eol End Of Line convention; how lines are terminated. "unix" for linefeed, "mac" for carriage return; "windows" for carriage return plus linefeed. charset The character encoding of the output. Defaults to UTF-8. locale The locale to use for number and date formatting. Defaults to the current locale as reported by locale(1). Consult locale -a out- put for acceptable values. quote The character or string used for quoting fields. Defaults to """ (quotation mark / double quote). separator The string used to separate fields. Defaults to space. format How cells should be formatted. Acceptable values: "automatic" (apply automatic formatting; default), "raw" (output data raw, unfor- matted), or "preserve" (preserve the formatting from the source document). This deals with the difference between a cell's contents and the way those contents are formatted. Consider a cell in a Gnumeric input document that was input as "4/19/73" in a US locale, with a format set to "d-mmm-yyyy" and thus formatted as "19-Apr-1973". With the default format setting of "automatic" it will be output as "1973/04/19". With "preserve", the formatting will be preserved and it will be output as "19-Apr-1973". With "raw" it will be output as "26773" (Gnumeric's internal representation: days since an epoch). transliterate-mode How to handle unrepresentable characters (characters that cannot be represented in the chosen output character set). Acceptable values: "transliterate", or "escape". quoting-mode When does data need to be quoted? "never", "auto" (puts quotes where needed), or "always". Defaults to "never". quoting-on-whitespace Controls whether initial or terminal whitespace forces quoting. Defaults to TRUE. EXAMPLE
To convert the Gnumeric file foo.gnumeric to a Microsoft Excel(TM) format file foo.xls: ssconvert foo.gnumeric foo.xls The export format can be specified explicitly, to override the default (which is based on the file extension): ssconvert --export-type=Gnumeric_stf:stf_csv foo.xls foo.txt To convert an Excel format file statfuns.xls to a text file, specifying the semicolon as the separator character: ssconvert -O 'separator=; format=raw' samples/excel/statfuns.xls statfuns.txt LICENSE
