xlsx CP932 Incorrect output

[Đào Văn Hùng]

This is my file: test.xlsx
This is my code:

cosnt wb = XLSX.read(await file.arrayBuffer(), { cellText: false, cellDates: true });

the output for Japanese: *���[���A�h���X and A-F�����N, very strange
it work well if I change to csv

The linked file is a CSV, not an XLSX file.

If you want to use CP932, you have to specify it:

cosnt wb = XLSX.read(await file.arrayBuffer(), { cellText: false, cellDates: true, codepage:932 });

If you are using ESM, you need to manually load the encodings. https://docs.sheetjs.com/docs/getting-started/installation/nodejs#usage describes the configuration in more detail.

@SheetJSDev
thank you
but sometimes, I'm not sure about the input file's encoding
so set codepage: 932 as default is quite risk, have any way to make it auto-detect or I need to implement that logic?
cptable is able to do it?

Unfortunately "auto-detecting encoding" is out of scope. Excel automatically applies the computer regional settings when reading files. That is analogous to the codepage option.
