put csv data to array imacros js - web-scraping

Question

I am trying to loop through a csv file pushing each column into an array but I am not sure how to do that, I know that the tag {{!COL1}} will give me the data I want but I can't figure out how to save it into a variable I can use to push inside an array.
csvToArray = "CODE:";
csvToArray += "SET !DATASOURCE artist.csv" + "\n";
csvToArray += "SET !ERRORIGNORE YES" + "\n";
csvToArray += "SET !DATASOURCE_LINE {{CSV}}" + "\n";
csvToArray += "SET !VAR1 {{!COL1}}" + "\n";
for(i = 0; i < 10; i++){
iimSet("CSV", i);
iimPlay(csvToArray);
}
This code will allow me to loop through a csv file, and the {{!COL1}} tag gives me the data i want, how do i save this into a varialbe i can use, please someone help cant figure this one out. :(

Answer 1

To get the data of COL1 you will need to set EXTRACT = COL1, then assign your variable to iimGetLastExtract().
Add this to your macro:
csvToArray += "SET !EXTRACT {{!COL1}}";
Then add this to your js file:
var myArray = []; // place at top of file for readability
myArray.push(iimGetLastExtract()); // place at end of for loop
// puts each extraction into myArray

Answer 2

Try the below code block.
function read_file(path) {
var content = '', i = 1, f, res = '',spl;
while (1){
content = res;
if (content != "") {
spl = content.split("|");
//spl[0] will contain the Row1 and Column1 value, spl[1] will contain Row 1 and Column 2 value etc.,
/*Here you can specify your script/conditions
Example:
iimPlay('CODE:TAG POS=1 TYPE=INPUT:TEXT ATTR=NAME:login[username] CONTENT='+spl[0]);
iimPlay('CODE:TAG POS=1 TYPE=INPUT:PASSWORD ATTR=NAME:login[password] CONTENT='+spl[1]);
I used the infinite loop, so in order to come out of the loop, you need to add a condition like below
if (spl[0]=="End") {//In your input sheet if the Row1,Col1 contains the value 'End', then it will exit the loop
iimDisplay("All Rows Completed");
return;
}
*/
f = "CODE: "+"\n";
f += "SET !EXTRACT null" + "\n";
f += "SET !LOOP 3" + "\n";
f += "SET !DATASOURCE \""+path+"\" "+"\n";
f += "SET !DATASOURCE_COLUMNS 5" + "\n"; //Assume that you have five columns in the your input file
f += "SET !DATASOURCE_LINE " + i + "\n";
f += "SET !EXTRACT {{!col1}}|{{!col2}}|{{!col3}}|{{!col4}}|{{!col5}}" + "\n";
iimPlay(f);
res = iimGetLastExtract();
i++;
}
return content;
}
var file_conten = read_file("yourinputfilename.csv");
