can't find end of central directory

[wlpeter]

I upload one file which had about ten thousand lines of text, but it throw error. The error is "can't find end of central directory".

ERROR 24471 nodejs.Error: Corrupted zip : can't find end of central directory (uncaughtException throw 1 times on pid:24471)

@wlpeter This is reproducible with leading characters PK followed by two tab characters:

require('xlsx').read("PK\t\t123", {type:"binary"})

The fix is in bits/87_read.js:

-               case 0x50: if(n[1] === 0x4B && n[2] < 0x20 && n[3] < 0x20) return read_zip(d, o); break;
+               case 0x50: return (n[1] === 0x4B && n[2] < 0x09 && n[3] < 0x09) ? read_zip(d, o) : read_prn(data, d, o, str); break;

Well, repeated again with npm package xlsx (version 0.12.10)

@superlbr can you upload a file ?

Can't reproduce the issue against 0.12.10:

$ xlsx --version
0.12.10
$ xlsx ~/Downloads/0427.xlsx | sed 's/,*$//'

yeah, the file is ok.
But little change in saving from request's file stream.
Look out when fs.createWriteStream deal with xlsx file

Got this error using SZip v3.2.1 when using jszip.min.js

Can't find end of central directory : is this a zip file ? If it is, see

https://stuk.github.io/jszip/documentation/howto/read_zip.html

If I use jszip.js (not minified version) it works!

workbook.xlsx.readFile ..... will try to load xlsx file

that is a compressed excel file
so it will fail with this message :

_stack:'Error: Can't find end of central directory_

only try to use it on compressed excel file

if you want to load a csv file you need to use : _workbook.csv.readFile_
if you want a regular excel (uncompressed) then : _workbook.excel.readFile_
