After logging in to It's Deductible, choose, or create, a charity. Then go to the appropriate section, i.e. 'Women's Clothing'. Highlight the entire box, from the heading "# of items" to "Showing 1 to 84 of 84 entries", right click to 'copy' the highlighted area.
Then open your spreadsheet program. Right click in top left box, and select 'paste'. This has worked well for me.
