As a systems administrator, you often need to generate reports from data stored in Excel spreadsheets. Wouldn’t it be great if you could automate this process so that you could simply run a shell script and have the reports generated for you?
Luckily, this is relatively easy to do using a combination of the shell scripting language and the Excel application. In this article, we’ll show you how to use a simple shell script to automatically generate Excel reports.
First, let’s take a look at the shell script that we’ll be using. This script uses the “xls2csv” command to convert an Excel spreadsheet to a CSV file. The CSV file is then processed by the “awk” command, which extracts the data that we need and formats it into a report:
#!/bin/bash
#convert Excel spreadsheet to CSV file
xls2csv spreadsheet.xls > data.csv
#extract data from CSV file and format it into a report
awk -F, ‘{print $1 “,” $2 “,” $3}’ data.csv > report.txt
The first line of the script, “#!/bin/bash”, is known as the shebang. This tells the shell which interpreter to use to execute the script. In this case, we’re using the Bash shell.
Next, we use the “xls2csv” command to convert the Excel spreadsheet to a CSV file. The output of the “xls2csv” command is redirected to a file called “data.csv”.
Finally, we use the “awk” command to process the CSV file. The “-F,” option tells “awk” to use commas as the field separator. We then print the first, second, and third fields from the CSV file (which correspond to the columns in the Excel spreadsheet) and redirect the output to a file called “report.txt”.
Now that we’ve seen the script, let’s try running it. First, make sure that the script is executable by running the “chmod” command:
$ chmod +x script.sh
Then, simply run the script:
$ ./script.sh
If everything went well, you should now have a file called “report.txt” in the current directory. This file contains the data from the Excel spreadsheet, formatted into a report.
As you can see, it’s relatively easy to automate the generation of Excel reports using a shell script. This can be a great time-saver if you need to generate reports on a regular basis.

How do I make an Excel spreadsheet a shell script?
There is no built-in way to make an Excel spreadsheet into a shell script. However, there are a few ways to accomplish this:
1. Use a third-party utility, such as xl2sh from http://xl2sh.sourceforge.net/.
2. Save the spreadsheet as a CSV file, then use a CSV-to-shell script converter utility, such as csv2sh from http://csv2sh.sourceforge.net/.
3. Use a general-purpose scripting language that can read Excel files, such as Perl, Python, or Ruby. Then use the language’s facilities to convert the spreadsheet data into shell script code.
