UNIX for Advanced & Expert Users

Hi, My client uploads an Excel file on to Unix server by using web application with more than 20 columns and more than 60000 records in it. I have to check the data in each cell when the file arrived. Is is possible to check the data in cells by running unix script? or Is there any way to convert this excel file as delimter file (programatically... purely in unix) and check by using script. Its not posible to open these files using open office or other tool etc...I need the solution purely by writing the unix script file as I need to set this as cron job.

Any one help highly appreciated and Thanks in advance.

Sireeshp,
To read each cell in the file try this:

Code:

while read InpLine
do
  echo "InpLine = "$InpLine
done < input_file
Does this help you?

Ask them to send it up as a CSV or tab-delimited file.
