I'm trying to make my own worksheet to object-array in node with exceljs. Basically I want to turn the rows to objects with the first row's values being the key and the actual row's values being the value. I get back an object with the right keys but always the same values (namely the last row's values).

What am I doing wrong? Is it the async? Also ignore the empty item, I know it's bad index.

How to save excel workbook using Javascript

Asked 2021-Dec-13 at 14:54

I have created an HTML form that takes in user data and using exceljs and a few other libraries I store this data into an excel spreadsheet. This part of my code works perfectly fine. However, when I refresh the server, the data stored in the excel file previously gets deleted.

I believe the reason is that I could not save the excel workbook....but when I searched up for some code to achieve this and executed it...the code didn't work.

Here is the code that collects user data into the excel worksheet:

ANSWER

Answered 2021-Dec-13 at 14:54

Your code is working fine. The issue is, each time your server is restarted, you are recreating a new excel file with same name.

You have to implement some extra logic to check if the file already exists in the server. If so, then don't create the file, just append the new row to the existing file otherwise create a new file and save the data.

I have added below working example:
