# Excel output append

I currently have the following codes:

output = Grid [{{"fiscalyear", "companyname", "keyword1frequency",
"trapwordfrequency", "keyword-trapword"}, {fiscalyear,
companyname, keyword1frequency, trapwordfrequency, secondDV}}]

Export[StringJoin["C:\\Users\\MyLaptop\\Desktop\\Test\\",
TextString[fiscalyear], "_", TextString[companyname],
".csv"], output]


which gets me an excel output with a line that has fiscal year, companyname and other variables. However, this output has only one line but i want to run my main code more than 100 times such that i could append the next company's information right below (next row) each company. Could anyone help please? The above code would generate 100 excel files if i were to run the code 100 times but i would like one file with 100 rows instead!

res= Table[compute[i], {i,1,100}];
