I did some performance test, just compare exceljs with https://github.com/SheetJS/js-xlsx/ and xlsx-populate js lib.
js lib and version:
xlsx.js@0.14.3
exceljs@1.11.0
xlsx-populate@1.19.1
I tested it on web browser.
exceljs vs xlsx.js vs xlsx-populate
parse .xlsx file:
1MB file parse:
882.985107421875ms
2481.923583984375ms
1339.385009765625ms
15MB file parse:
13153.964111328125ms
exceljs crashed
22480.077880859375ms
exceljs is so slowly.
any plan with better performance?
thank you.
