I have the Open Office, but it takes steps to get to my "Work" spreadsheet.
The old spreadsheet on my XP was fast and simple. I didn't have Excel on that? Just what it came with when I bought the cheap $400.00 Emachine computer. I think it was called Microsoft Works???
Yes and now you are between a bit of a rock and a hard place. A lot of computer manufacturer's for some reason came bundled with Microsoft Works Productivity Suite of various versions and the products (documents, spreadsheets, databases) are a bit proprietary in their file format.
The first thing you need to do is make a copy of your original file so as not to destroy or corrupt the original. Use only the copy to experiment with any type of conversion.
Open the copy in "Works" on you old XP computer and choose "Save As" depending on which version of "Works" you have your options may very, but use the drop down arrow in the files of type box and choose the latest version of the Excel (.xls) available to you.
To Convert a Works for Windows spreadsheet to Excel 97
- Open the spreadsheet file in Works for Windows.
- On the File menu, click Save As.
- Under Save File as Type, select the appropriate converter:
Works for Windows 4.0, 4.0a, 4.5, 4.5a: click Excel SS Works for Windows 3.0x: click Excel 4.0/5.0 SS
- Click Save.

Put that file on your thumb drive and transfer it to your new Windows 7 Machine where you have Open Office installed and open it and see what you end up with. Keep in mind that if it's a complex spreadsheet there may be some formatting issues, formula corrections, etc., which you may need to have to correct in order for it to function as before.
There are other options that are also available that may help.
You can perhaps export it as a "Comma Separated Value" .csv document and then import it into a new spreadsheet in Open Office.
or
You can look into the "Works Document Converter"

Again, preserve the original file and only work with a copy of the file.
EDIT: You can probably forget about the "Works Document Converter" as it seems to only work with the Works document format and not the Works spreadsheet format.
