Why is it important to validate the data in a worksheet before sharing it?

Validating data in a worksheet is essential primarily to ensure that the results align with the intended expressions. This process involves checking that formulas and calculations are producing accurate and expected outcomes based on the data entered. If the data has not been validated, it may lead to incorrect conclusions or decisions, as users may rely on erroneous values that don't reflect reality.

When sharing data, especially in a business context or for decision-making purposes, it’s crucial that all stakeholders can trust the integrity of the information. Accuracy in data not only fosters confidence in the results but also aids in achieving the desired objectives without complications that stem from misinformation.

Focusing on other elements, such as making the data visually appealing or reducing file size, are secondary to ensuring the data's correctness. While loading speed might be beneficial for user experience, it does not substitute the need for validating the underlying data that informs crucial business or operational decisions.
