I have a user who was working on an Excel 2007 file from a thumbdrive.. all of a suddem the file will not open and generates the following error:
"Excel cannot open the file 'filename.xlsx' because the file format or file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file. (OK)"
I hit Ctrl-Shift-i to get the code for that error (101590)
Any ideas how to repair?
I have tried the following to no avail:
Open and Repair tool
Opening with OpenOffice
http://office.microsoft.com/en-us/excel-help/repairing-a-corrupted-workbook-HA010097017.aspx
http://support.microsoft.com/kb/928979

First try to rename file. Go to tools, folder options, file types and check have you .xlsx extension. If not then rename the file .xlsx to .xls
Second try to look here: https://social.technet.microsoft.com/Forums/en-US/4994c2f4-ce6e-467d-a06c-d9ab7d67b706/i-have-a-case-that-the-client-work-on-an-exists-excel-file?forum=excel

I have downloaded the following file on my Linux computer:
wget https://github.com/tomwhite/hadoop-book/blob/master/input/ncdc/all/1901.gz
I tried to unzip the file using gunzip 1901.gz but it did not work. I check the file format using 'file' command and it says:
1901.gz: HTML document, UTF-8 Unicode text, with very long lines
I am quite new to Linux. May I know how can I successfully extract the data for usage?
You have downloaded a regular HTML file and you called it something.gz, hoping that that would turn it into a zipped file, but this is not how it works: your file is not a zipped file, so there's no reason trying to unzip it.

I there any unix command which will convert xls file into xlsx file?
Also i have tried using mv command, it is changing the extension as well. But then i am not able to open the xlsx file.
mv .xls .xlsx
Any suggestion will be really appreciate.
As far as I know, this is not something you can easily do with standard unix tools.
You can use LibreOffice:
libreoffice --convert-to xlsx my.xls --headless
Or maybe find an online converter and submit your file to it.

I would like to know if there is a reason to not use .xlsb file format all the time, instead of .xlsx or .xlsm?
I've looked at this post: When should the xlsm or xlsb formats be used?
and also done some basic tests myself, it seems binary format is way superior. So I'm curious to know whether I shouldn't just use .xlsb all the time and say goodbye to .xlsx or .xlsm. Is there a catch somewhere?
The only reason not to use .xlsb is for compatibility reasons since since many other software applications cannot handle the format.

I have several emails sent to me each day which all contain a hyperlink to a local file in a directory.
I would simply like it to open the link in excel but instead it opens Internet Explorer and then says 'Internet Explorer cannot display webpage'
Is there a way I can change it so it opens in Excel and not IE?
Many thanks,
Mw
check that Excel is the default program for the file extension. Alternatively you could edit the hyperlink to start with "C:\Program Files\Microsoft Office\Office12\excel.exe" with the file path following. (make sure that you edit the path for your version of Excel.

A strange thing happened. A file my father was working in one of his Excel files was corrupted while he was saving it, resulting in the file being deleted.
Of course he didn't delete the file himself. Needless to say he came to me to find a solution.
So after some Googling I came up with a file recovery tool (PC Inspector File Recovery) and I found a deleted file.
The only problem is, the size of that file is less than 1kB, but it is an .xlsx file. Among that file there are also two other .tmp files, one is dating from a minute after the .xlsx-file was last edited, the other 6 hours later from the .xlsx-file. Both files are 171kB in size.
I'm suspecting the data from the original excelfile is in those files (I think the second file, is some copy of the first tmp file).
Does anyone know if I can restore these tmp-files into the original Excel file?
Have you tried just renaming it from .tmp to .xls and seeing if it would open?
