Parsing a file with a large number of rows

[apitts]

Parsing 5,000 rows takes a few seconds but 30,000 rows just seemed to hang / not work. I stopped it after a few minutes though. I would have thought time would scale linearly with the number of rows but that appears not to be the case?

I have the same problem!
If I try to parse a file that has more than 5000 rows, I get this error:

.../node_modules/excel/node_modules/node-promise/promise.js:147
throw new Error("This deferred has already been resolved");

More than 11 months nothing changed, so is this module still alive?
Would be great if you can solve the the problem because its a great module!
I really appreciate any help you can provide.

Is it alive? It appears to be useful to some still, but nothing is being done to improve it.

You might have better luck with https://github.com/mgcrea/node-xlsx.

Same issue. Seems that it doesn't scale linearly. Will try to get it work with another lib.

@beflori I know it's been a long time, but out of curiosity, do you (and did you at the time you were looking into this) know about https://github.com/SheetJS/js-xlsx? If so, why use excel.js instead of that? I haven't worked on this in a long time, and I wonder if I should just point people to that other option, or if there's something compelling about excel.js that I should make more clear or enhance.

[beflori]

It worked for us with node-xlsx and I wasn't aware of a better lib back then. Parsing Excel files seems to be error prone.
