Worksheet.Eachrow Break or stop

Hi, i have tried your npm package, lets assume one scenario,

i have uploading sheet and reading data, in that first record i got error, then have to send res.send error statuscode with client side message. Still now also eachrow loop continue, after i have sent the response. i need to break(stop) the loop.

worksheet.eachRow({ includeEmpty: false }, function(row, rowNumber) {

//here i'm doing some validation, the upload data was wrong. so i have to stop the loop don't want further process.

// currently i have pass the error message using res.send but the loop was hitting again and again.
and also i have getting unhandledrejection warning message how can i avoid.
});

@harloveleenKaur Using a return statement doesn’t work. A return in the iteratee doesn’t break the loop.

But you’re right about throwing an error:

try {
  worksheet.eachRow({ includeEmpty: false }, function(row, rowNumber) {
    if (/* Validation of the row fails */) {
      throw new Error();
    }
  });
} catch (error) {}

Hi @ahdigital,

This is @GRathinavelu (From Personal Id),

I have tried based on which i mention previously, after some google i have go with ALASQL, use the npm of multer move the files to my server, and use the path to get the data based on my SQL QUERIES.

npm i alasql

if i need to validate some kind of data is available or not, i have simple use select * from tbl where some quires. we don’t need to loop that, and also we create temp tables also on run time.

So, as per my case I HAVE SUGGESTED ALASQL instead of EXCELJS
