Can you open the file  in excel? What happens when you try? Can you open,
save, and re-open other excel files?

Before you do anything with it, copy the file and ONLY work on the copy -
otherwise you may destroy what is in the file you are using.

Do you know how it became corrupted?

Do you have another copy of the file or a backup anywhere?

If you cannot open the file you may need to

I can open the file  but there was several pages (sheets) which are
merged into a single page(sheet), I could not read the records because
all those records (both numerical and text) changed into symbolic (I
don't know ASCII or what) format. When I tried to open using repair
option the data are converted into numeric value and I could alos see
the various sheets but there is no any text (name & address of account
holders) so it is difficult to distinguish the accounts by name.

I do not understand what has happened. If you wanted to send me a copy of
the file, I could have a look at it for you - no promises I can fix it
though!

However, if the font used is a double byte font I just do not have the
relevant language packs (or knowledge) to deal with it.

If you do want me to look at it my email is yahoo at grugeon dot com dot au.

I have not been able to recover the data. I do not have excel
2007 and the file  is an xslx file. It converts to and opens in Excel 2003
but the data is clearly not what is expected.



I think it needs someone who has a binary file editor and can look inside
the file (and understands the xlsx format) to find out what is wrong.

If the problem  involves 2007 file  and 2003 Office, this may help

Thanks for the suggestion. I have the converters but the file  as converted
seems to be corrupted. It opens OK but has only one sheet and a lot of
garbage in it. I would suspect that the compression program which generated
it in the first place misfired somehow.
