Uncaught TypeError: Cannot read property 'length' of undefined about sheetjs HOT 6 CLOSED

@chethiya Thanks for pointing this out!

This is actually a Web Worker issue. The SSF object is currently locked to the XLS instance, and there are actually two floating around: one from the index.html and one from the webworker. When the csv function is called, the XLS instance is the local one (not the worker), so it has no information regarding custom formats.

To verify that this isn't a library issue, disable the Worker by changing the line if(typeof Worker !== 'undefined') { to if(0) {. Alternatively, if you have node, the xlsjs module provides a command xls2csv which you can run. If you still see a problem, please post a file so I can take a look

The right thing to do here is to attach the format metadata to the workbook object (so that the formats are contained and the data can pass through the WebWorker divide), and the straightforward fix will be pushed after some tests (and some much-needed sleep)

from sheetjs.

Thanks for the detailed explanation.

It worked both ways fine!
