Corrupt Excel files

I am extracting a lot of datawith SSIS 2005 ... DB to excel, every time i try to pull a certain date range the file is corrupt. I have even tried to go file open / repair and just Extract the data but the file is still corrupt. I have
pulled 50-60 files from the same database with out any problems and this file on extract does not throw any errors. Any ideas to get this data, or what could be corrupting the file? I am not receiving any errors on export

This is another example of improper use of Excel which is a desktop app, not a data interchange format.
I do not have any experiencing with recovering corrupt Excel files and an Excel forum could be a better place to ask.
But I suggest you try to reliably repro the issue and share with us how to corrupt then we will see how to help.
At this point in time I can only suggest you should use the IMEX=1 setting in the Excel conn string as it puts it into the Import data mode.

Corrupt Excel files in Windows 7

i use excel 2007 . most of excel files open ok . Some of them (.xls) , produced by some sql software, wont open in windows 7 . I tried everything , from compatibility modes , remove antivirus software , etc. the system says that file wont open and that is corrupted , trying to restore it nothing happens . Though in other windows versions these files works ok.

Hi,
What version of Excel were they using?
Have you tried opening it up in the latest version on Excel?
I had it in the past where says a 2003 file wouldn't open but opening it in 2007/2010/2013 it would repair it & open it ok.
Then I just saved the file to a new location.
Have you tried Open Office? might be worth a try just in case?

Corrupt Excel files created on my Mac

Help!
I recently created a basic Excel file on my iMac G5 using the Microsoft Excel program. I tried opening the spreadsheet and it states:
The file cannot be accessed. The file may be read-only, or you may be trying to access a read-only location. Or, the server the document is stored on may not be responding.
I tried re-opening as as read-only, I tried re-locating the file to my external drive and I tried opening with Word. But, with no success.
Any help would be greatly appreciated!!

Hi,
I think you need to recover the excel files. You may try Advanced Excel Repair at http://www.datanumen.com/aer/ This tool is rather useful in salvaging damaged Excel xls files.
Hope this will help.

How to make restoration of corrupted excel 2007 file?

Hi there,
When I open an excel file the following error message is displayed: “The file may be corrupted, located on a server that is not responding, or read only”.
Since this happened whenever I open any excel file, the above error message is again displayed, I must also mention that I am sure my files are not read-only and the files are stored on my hard disk and I use VM ware and my OS is windows server!
How can I solve this problem?

You may copy the file to another computer with Excel installed, and open it. If the error still exist, then your file is corrupt. Otherwise, there may be some problems with your Excel in the original computer and you need to uninstall/reinstall Excel.
If the file is corrupt, then you can try several methods to recover it:
1. First of all, you can try to repair the file manually in Excel, as follows:
(1) On the File menu, click Open.
(2) In the Open dialog box, select the file you want to open, and click the arrow next to the Open button.
(3) Click Open and Repair, and then choose which method you want to use to recover your workbook.
You may find more information about this at:
http://office.microsoft.com/en-us/ex...001034656.aspx (for Excel 2003)
http://office.microsoft.com/en-us/ex...017.aspx?CTT=1 (for Excel 2007)
http://office.microsoft.com/en-us/ex...840.aspx?CTT=1 (for Excel 2010)
http://office.microsoft.com/en-us/ex...554.aspx?CTT=1 (for Excel 2013)
2. If method 1 fails, there are still several methods to recover your Excel file manually with Excel, including writing a small VBA macro, as below
http://office.microsoft.com/en-us/ex...#_Toc337637262
3. Third, there are also free tools from third-parties that can open and read Microsoft Excel files, for example,
3.1 OpenOffice at http://www.openoffice.org. This is a very famous open source project that is designed to support Office file formats, including Excel files. The software can run under Windows.
3.2 KingSoft Spreadsheets at
http://www.kingsoftstore.com/office/free-excel. This is a free Windows tool that can open Excel files.
3.3 Google Drive at https://drive.google.com/ also support to load Excel files.
Sometimes when Excel fails to open your file, these tools may be able to open it successfully. If that is the case, then after the Excel file is opened, you can just save it as a new file which will be error-free.
4. For xlsx files, they are actually a group of files compressed in Zip file format. Therefore, sometimes, if the corruption is only caused by the Zip file, then you can use Zip repair tools such as WinRAR at
http://www.rarlab.com to repair the file, as follows:
4.1 Assuming the corrupt Excel file is a.xlsx, then you need to rename it to a.zip
4.2 Start WinRAR, go to "Tools > Repair Archive" to repair a.zip and generated a fixed file a_fixed.zip.
4.3 Rename a_fixed.zip back to a_fixed.xlsx
4.4 Using Excel to open a_fixed.xlsx.
There may still be some warnings when opening the fixed file in Excel, just let ignore it and Excel will try to open and repair the fixed file. If the file can be opened successfully, then you can just save the contents into another error-free file.
5. If all above methods do not work, then you may try third-party tools such as DataNumen Excel Repair at
http://www.datanumen.com/excel-repair/
I have used it to recover some Excel files successfully. It provides a free demo version so that you can try to see if the data you want can be recovered or not.
Good luck!

Recovery a password protect excel file.

I have a password protected excel file and now it's corrupted and i can't open it. I tried to open_and_repair feature of excel2010 and different other stuffs, without success. I was wondering if there's a way to remove the password without opening the excel
files (i know the password). In this way maybe it'll be easier to repair the file. Is there a way to do this? What other things i could try?

Hi,
There are several methods to recover Data in Corrupted Excel Files.
We can use the following methods to troubleshoot problems with opening or using Excel
files:
Use a recovered copy of the document.
Use the
Open and Repair command.
Save the file in HTML format.
Save the file in XML Spreadsheet format.
If a chart is linked to the corrupted file, use a macro to extract the data.

How to repair excel file?

I have a corrupted excel file, in the sense , when I try to open my excel file, it says it is corrupted and the file has some Unsupported data and if I proceed to open, it says the Unsupported data cannot be repaired or removed. Function Open and Repair
doesn't help me. I'm using MS Excel 2013 on Windows 7 Ultimate.

Have a look here:
http://www.excelrepairtoolbox.com/
Still facing same problem then I will recommend you to try Excel Repair Toolbox
The following steps might help recover your file:
1. Click the File menu
2. Click Open
3. Locate the file, but do not click the Open button. Instead, click the drop-down arrow next to the Open button.
4. Click "Open and Repair"
5. In the dialog that pops up, choose "Repair". If that does not work, try the "Extract Data".
6. Let us know if this works. If not, we will see what else we can come up with for you.
Thanks

Problem repairing excel file in office 2010

Hello,
I have a problem with one of my excel file, I was working on file in excel and computer suddenly restarted due to electricity fluctuation. After computer restarted, I try to open the file but it gives error.
"Excel cannot open the file 'myfile.xlsx' because the file format or file extension in not valid. Verify that the file has not been corrupted and that the file extension matches the format of file."
I try to repair the file using repair tool of Excel 2010 but it is useless. I also tried different software to recover corrupted excel file but all useless.
Does anyone has solution to make my file useful.

Excel file on Sharepoint is corrupted.

Hi all,
I face a problem with an excel file which I share with my colleagues on the SharePoint. The file has macros and pivot tables and also a sheet that users add inputs. This sheet has data validation rules to ensure that users add certain values. The users access
the online version on the SharePoint and add their inputs in the online version.
It happens regularly that my file is corrupted. When this error occurs I take the message: "Errors were detected while saving". In addition, my code doesn't run and it appears the message "error in loading DDL".
I have also noticed that the size of the file is smaller when the file seems to be corrupted. Users are supposed to add information and not delete every week.
Could it happen because a user has a different excel version or his office program needs repair?
Could you please help if you have faced the same issue?
Thanks

You might be able to open the workbook my disabling the macros before opening the file. (Tools > Macro > Security ). I had a similar problem and this helped get me back into the file.

Excel file corrupt after saving to another disk

I have two PCs at home.: A laptop running Win-7 64-bit, and a desktop running Win-7 32-bit. Both are running Office 2010. Often, but not always, when I save an Excel workbook from one PC onto a shared hard drive on my home network and
then try to open it on the other PC, the other PC displays the "file appears corrupt, would you like Excel to try to recover/repair?" message when I try to open the file. This also happens sometimes when saving to a thumb-drive and attempting to open
it on a non-connected laptopn running XP and Ofice 2007. Most times, Excel successfully repairs/recovers the file without issue. Infrequently, it doesn't repair everything. Today it failed completely and was unable even to open the file on
another PC. I've tried various methods to copy the file. I've experienced the problem when I use Windows Explorer to copy the file from one disk to the other, and also when using both DOS COPY and XCOPY commands. The issue occurs with
many, but not every Excel file I copy. And it doesn't happen every time - only sometimes. It seems to occur more frequently with certain specific files, and and rarely or never happens with specific other files. It occurs in both directions
(i.e. with both the 64-bit Win-7 machine as the "source" machine and with the 32-bit Win-7 machine as the source machine.) All of the files I have problems with are .xlsm files. I have not tried to confirm that it happens only with .xlsm
files. It doesn't seem to matter if the destination file is being overwritten, or if it is being created from scratch by the copy source. I'm baffled. Any suggestions as to why this is happening? How I can prevent it? Thanks.

Hi,
The Office 2010 you used on both computers are 32-bit or 64 bit?
There are some differences between Office 32 bit and 64 bit.

Numbers 2.1 when exported as an excel file and my application tries opening it, it says file contains corrupt data.

I recently updated my iPad to the latest iOS 7 and updated my numbers app to 2.1. When i export it to a excel file and then when my C# application(using gembox library) tries reading it, i would get an error "file contains corrupt data". before making the update to iOS 7 and before updating my numbers the process worked fine!

That didn't work for me and the page times out right about 5
minutes (300 seconds). I don't have timeout checked in the CF
Administrator so I don't think it is CF that is causing the
timeout. I checked IIS also and the timeout is set to 900 seconds.
Is there a possibility that SQL Server has some sort of
connection limit and I'm using too many cfquery tags? If anyone has
experienced a similar problem I would really appreciate the help,
thanks.

Thank you. Chandu Kerai

Sorry, it's my my fault. Please try to perform the basic throubleshooting steps for Excel which lists in the link below and check if the issue still persists.
http://support.microsoft.com/kb/2758592/en-us
Most of steps have been mentioned by
Keith Ruck in the first reply but you may try the rest.
Review the event log from your initial post and the error message is general. We need to use some tool like Process Monitor for further tracking that and analyze deeply.
For the crash/hangs issue, use ADPlus.vbs to have a try.

Error reading zip file containing an excel file

Hi all,
Using servlets I am able to zip an excel file using java.util.zip package. The excel file is created using POI API.
While I save and extract the zip file on my machine and then open the file in MS Excel. Excel pops a message saying "MS Office Excel has encountered a problem and need to close" and it gives me an option to "Recover my work and restart MS Office Excel". I select the option and then MS Excel does a document recovery and I am able to view my data. I get an excel repair log file saying as follows
"Microsoft Office Excel File Repair Log
Errors were detected in file 'C:\Documents and Settings\JohnDoe\Desktop\excel\test.xls'
The following is a list of repairs:
Damage to the file was so extensive that repairs were not possible. Excel attempted to recover your formulas and values, but some data may have been lost or corrupted.

Jdcunha,
I am new to the field but encountered the same problem and recently found a solution. Hope this helps.
For my project I wanted to create individual Excel 2003 workbooks for each file I created. Excel would give me the same error it gave you when I used the same HSSFWorkbook object. I tried creating a new Workbook object each time, but ran into the same issue.
I ended up fixing the error by creating a new instance of my write-to-excel class each time I wanted to create a new workbook, instead of just recreating a new HSSFWorkbook object. It works perfectly and the Excel errors don't show. It may also be important to note I used OutputStream, I did not try it with printwriter.

After I Update to IOS 7.1 I can't open the excel file attached in my email

Hi Alex,
The trick to this whole thing is to scroll to the bottom of the message. There should be a dashed line at the bottom of the email message with text underneath it that says, "This message was downloaded as plain text." Underneath that it should say (in blue hyperlink text) "Download full message". Select that hyperlink, and the Excel file should download completely. You should then be able to select the document and have it open correctly.
I have had the same concern regardless of file format that is sent, so I do not believe your issue is with file format. Hope this helps.
I've seen the same thing happen with images, which it displays in a corrupted form. It's fixed by downloading the full message.
There's a more serious side effect of this, which I've now seen with several types of files. If one FORWARDS the email to someone else, the attached files it sends them are CORRUPTED and unopenable too. In the case of a Word files I looked at, it had dropped the last two bytes of the file.
The workaround for that is to download the full message before forwarding.
I'm seeing this happening with so many types of attachments that I'm assuming it affects them all. Please everyone report this to Apple feedback (http://www.apple.com/feedback/). It's one thing not being able to open a file on your device, it's another to have files corrupted permanently just by forwarding.

Firstly, Thanks for Your quick Response, Thomas.
Even though what ever may be the file name I am passing either info.xml or Info.xls , In error info.xls is coming.
Kindly provide me an alternative on this XML doesn't seem like it would match the 'application/vnd.ms-excel'.
what is the supported format.?
