If you want to do this automatically without manually opening the spreadsheet program, you can write a script for that. Save the files as CSV (Comma Separated Values) or TSV (Tab Separated Values). Excel will work with both. I will assume TSV.
Here, then, is the synopsis of the problem
. We want to copy cell A2 (second row, first column) from C:/file1.csv to C:/file2.csv.
# Script A2.txt
# Read file1.
var str content1 ; cat "C:/file1.csv" > $content1
# Get second row of content1.
var str row2 ; lex -e "2" $content1 > $row2
# Get first column of row2.
var str column1 ; wex -e "1" $row2 > $column1
# We now have the value of cell A2 in $column1. Read file2.
var str content2 ; cat "C:/file2.csv" > $content2
# Extract the first row of content2 unchanged into output.
var str output ; lex -e "1]" $content 2 > $output
# Put in the extracted value of cell A2.
echo "\n" $column1 "\t" >> $output
# Put in the rest of data from content2.
wex -e "[2" $content2 >> $output
# Output is ready. Write it back to file2.
echo $output > "C:/file2.csv"
Script is in biterscripting ( http://www.biterscripting.com
) . To try, save the script as C:/Scripts/A2.txt, start biterscripting, enter the following command.
The script can also be called from the task scheduler, if you want to schedule a monthly task. I am calling the script A2 because, we want to extract cell A2 here. But, you can change the script to extract any other cell, or even multiple cells.
