Using the data in the Alphabet Financials.xlsx workbook that was used in the chapter:

a$.$ Convert the balance sheet into a format that is suitable for a pivot table by transposing the data using Get & Transform. Don't forget to enter the word "Date" above the dates.

b$.$ Build a pivot table from the data showing Total Assets by Quarter. Add a pivot chart showing how total assets have grown over time.

c$.$ Create a calculated field that shows the current ratio in the pivot table, and format the numbers with two decimal places.

d$.$ Create a pivot chart that shows the current ratio over time. Has Alphabet's liquidity deteriorated or improved over this period? Insert a trend line into the chart to verify your results.

E$.$ Now, use a Timeline to filter the pivot table so that it only shows $2018$ to $2019.$ Now show only $2013$ to $2014.$ Is there a difference in the trend of the current ratio in the two time periods?
