Is it possible to read excel using js?

Question

JavaScript

Is it possible to read a local excel file using js or chrome api?
This must be done in the browser extension.

Answer 1

There is such a package for reading Excel, https://www.npmjs.com/package/xlsx
If you need a local file, then you cannot access the user's disk, it is prohibited by the browser.
At best, there is a sandbox ( https://developer.mozilla.org/en-US/docs/Web/API/F... ), local file requests, and a FileReader.
