Custom Formatting vs. Preset Formatting
While custom formatting provides you with added flexibility when presenting data, it should not always be the default formatting option. The benefit of custom formatting is its ability to neatly display data with added descriptors without risking the accuracy of your calculations. However, if the preset formatting options work for your data then they should be used. Preset formatting options can satisfy many situations and include general, number, percentage, date, time, currency, accounting, scientific, fraction, and text.
