    English Answer：
    Excel Score Conversion to Grade.
    Excel is a powerful tool that can be used for a variety of tasks, including converting scores to grades. This can be a helpful feature for teachers and students alike, as it can save time and effort.
    There are two main ways to convert scores to grades in Excel: using a formula or using a lookup table.
    Using a Formula.
    The formula for converting a score to a grade is:
    =IF(score>=90,"A",IF(score>=80,"B",IF(score>=70,"C",IF(score>=60,"D","F"))))。
    This formula compares the score to a series of thresholds and returns the corresponding grade. For example, if the score is 90 or higher, the formula will return "A". If the score is between 80 and 89, the formula will return "B". And so on.
    Using a Lookup Table.
    A lookup table is a table that contains a list of scores and their corresponding grades. To use a lookup table to convert a score to a grade, you simply need to find the score in the table and look up the corresponding grade.
    You can create a lookup table in Excel by using the VLOOKUP function. The VLOOKUP function takes three arguments: the value you want to look up, the table you want to look up the value in, and the column number in the table that contains the value you want to return.
    For example, the following formula would create a lookup table that converts scores to grades:
    =VLOOKUP(score,A1:B6,2)。
    In this formula, A1:B6 is the range of cells that contains the lookup table, and 2 is the column number in the table that contains the grades.
    Which Method Should You Use?
    The best method for converting scores to grades in Excel depends on the specific needs of your project. If you need to convert a large number of scores quickly and easily, then using a formula is the best option. However, if you need to convert scores to grades that are not based on a simple threshold system, then using a lookup table is the best option.

    Excel 分数转化等级。
    Excel 是一款功能强大的工具，可用于多种任务，包括将分数转换为等级。这对老师和学生来说都是一项有用的功能，因为它可以节省时间和精力。
    在 Excel 中将分数转换为等级主要有两种方法，使用公式或使用查表。
    使用公式。
    将分数转换为等级的公式为：
    =IF(score>=90,"A",IF(score>=80,"B",IF(score>=70,"C",IF(score>=60,"D","F"))))。
    此公式将分数与一系列阈值进行比较，并返回相应的等级。例如，如果分数为 90 或更高，公式将返回 “A”。如果分数在 80 到 89 之间，公式将返回 “B”。依此类推。vlookup的使用方法图解
    使用查表。
    查表是一个表格，其中包含分数及其相应等级的列表。要使用查表将分数转换为等级，您只需在表中到分数并查相应的等级即可。
    您可以在 Excel 中使用 VLOOKUP 函数创建查表。VLOOKUP 函数需要三个参数，要查的值、要查值的表格以及表格中包含要返回的值的列号。
    例如，以下公式将创建一个将分数转换为等级的查表：
    =VLOOKUP(score,A1:B6,2)。
    在此公式中，A1:B6 是包含查表的单元格区域，2 是表中包含等级的列号。
    您应该使用哪种方法？
    在 Excel 中将分数转换为等级的最佳方法取决于您项目的特定需求。如果您需要快速轻松地转换大量分数，那么使用公式是最佳选择。然而，如果您需要将分数转换为不基于简单阈值系统的等级，那么使用查表是最佳选择。
