In this case it is usually easier to start again from the beginning, wasting the work done previously. Without documentation, the original purpose and methodology is often unclear and difficult to decipher.

Many users prepare a simple worksheet which then develops into something much moreĬomplicated over time. Lack of documentation is a very common failing. Breaking complex formulas down into more managable parts, described below, also helps to minimize errors and aid troubleshooting. What-if type calculations also are simplified: what if the exchange rate varies from 0.75 to 0.70 or 0.80? No formula editing is needed and it is clear what rate is used in the calculations. It is much easier to set up an input cell with the exchange rate and reference that cell in any formula needing the exchange rate.

If you input a formula in cell C1 of =0.75*B1 (for example to calculate the value in Euros of the USD dollar amount in cell B1), you will have to edit the formula when the exchange rate changes from 0.75 to some other value. For example, conversion from one currency to another requires knowledge of the current conversion rate.

Many users set up long and complex formulas with fixed values typed directly into the formula.

Not incorporating a system of checking to verify that the formulas do what is intended.

Not including notes and comments describing what the system does, including what input is required and where the formulas come from (if not created from scratch).

If you are setting up more than a simple one-worksheet system in Calc, it is worth planning ahead a little. Functions help you create the formulas needed to get the results that you are looking for. All you have to do is add the arguments, and the calculation is automatically made for you. In a spreadsheet, the variables are cell locations that hold the data needed for the equation to be completed.Ī function is a pre-defined calculation entered in a cell to help you analyze or manipulate data in a spreadsheet. Formulas are equations using numbers and variables to get a result. To handle this situation, we use a third type of data: the formula. Often the contents of one cell depends on the contents of other cells. However, we will not always know what the contents should be. In previous chapters, we have been entering one of two basic types of data into each cell: numbers and text.
