A business plan presentation is judged on its numbers, so Slidy never invents them. Revenue, margins, market size, loan amount, hiring plan: each figure on a slide is taken from the text you provided. If your plan mentions a break-even month but no revenue for year 3, the year 3 slot shows XXinstead of a plausible-looking guess.
This is deliberate. A banker or investor who spots one made-up number stops trusting the rest. Before exporting, search the deck for XX and either fill the value from your forecast spreadsheet or remove it. Slidy does not build your financial model or check that your forecast is realistic: that work stays with you or your accountant.
