How do you import financial statements in annual report to excel?

I'm supposed to construct a table of balance sheet and income statement and project it for 5 years by using financial ratios e.g. COGS/sales or sales growth rate. I also have to state my assumptions and construct at least 2 sensitivity analyses for areas which might concern the CFO (e.g. debt). I also have to calculate the NPV of FCF and estimate the valuation of the company based on FCF
