Number stored as Text error

In my code I’m formatting the numbers to strings with commas separators this way: num.toLocaleString('en') in order to get something like that: The problem is that this green sign appears and writes me “Number stored as Text” and that I need to convert it back to number manually. I didn’t find a feature that enables excel 1000 separator or ignores errors in this package. Is there something to do with it?

Hi, I was able to find solution for this. You have to return Number and numFmt should be #,#

Can you elaborate please?

When he says you need to return number, it means the type of data you are putting into exceljs for that row or column, should be a Number and not a string. Instead of using the toLocaleString, maybe you can just write in code the format you want so that it is never a string and uses something else to place decimals etc. Like in angular, I use the number pipe: {{yourField | number: ‘1.2-2’}}

When he’s talking about number formats, numFmt, I am fairly sure he is referencing actual excel number formats, which is what you put into your code when exporting. You can read about excel number formats here: https://www.excel-easy.com/examples/custom-number-format.html

For me, I had been using the method toFixed() on my data to get 2 decimal places, and it was turning it into a string. I removed that to keep it as a number, and when exported to excel, I no longer have the issue.
