TypeError !CompObj is not a function

Getting the above error with the following code:

Excel = require('xlsjs')
try
   workbook = Excel.readFile(uploadPath)
   console.log(workbook)
catch e
   console.log(e)

Also when I try the official demo with the same file, the error pops up in the console. The file is not corrupted and it happens with all files of the same type.

Any ideas?

@chaostheory newer versions of excel are not capable of generating BIFF2-4 files. They use a newer format (BIFF5 or BIFF8) which is why re-saving the file seems to fix the issue.

@JanSchuermannPH @Mithgol as part of this fix, we also added direct BIFF2 exports and filled some missing record types. The updated write script generates an xls file compatible with Excel 2.0

@Mithgol That’s one approach, but I’m leaning towards tweaking the CFB parser to add a unique field and check for that.
