Method 1 – Use the IF Function to Check If One Cell Equals Another and Return Another Value Case 1.1 – Returning the Exact Value of Cell We have a dataset of someFruitswith two columns. Every row has a specific Value. We will find the rows whereFruits 1andFruits 2are matched and dis...

In the Value_if_true field, type the value you want to be entered in your cell if B2 equals “Y”. In our example, I’ll click cell C3. In the Value_if_false: field, enter the value the cell should have if B2 does not have a “Y”. I’ll enter 0. I could leave it blan...

This is the exact opposite functionality of the equals sign (=), which will output TRUE if the values on either side of it are equal and FALSE if they are not.Let's take a look at the "does not equal" operator in action to see how we can use it in a simple formula:...
EEC是线程不安全的它不支持多线程读写,同时其为流式设计且只能顺序向后,这意味着不能通过指定行列坐标来随机读写,通常可以使用EEC来做一些日常的导入/导出功能,推荐在大数据量或性能/内存要求较高的场景或者没有随机读写的场景下使用。 目前已实现worksheet类型有以下七种,也可以继承已有Worksheet来实现自定义数据源...
