Adding a spreadsheet or any other LibreOffice file is easy using OLE Objects.

Here's How:

• Go to Insert→Object→OLE Object.
  
• You will be presented with this dialogue:
• As you can see at this point, you have two options, to create a new file, or to use an existing file.

Using a new file:

If you choose to create a new file, simply click okay, and you will be presented with a new, embedded file. (See below).

You can edit this as you normally would, without having to open an instance of Calc.

Using an existing file:

If you choose to use an existing file, click on the "Create from file" radio button. This will present you with some slightly different options:

• You can search for a file to use by using the "Search" button (it brings up a file dialogue where you can choose a file).

  

• You can use a local copy of the file by leaving the option "Link to file" unchecked.
  • This provides more flexibility, but takes up more space in your file.
• If you choose to link to the file:
  • It saves space
  • If you move the file, the link will be broken, so keep this in mind.
  • For best results, keep the files in the same directory.

Otherwise, everything else is the same as "Using a new file".
