By default, Excel displays ###### for negative time values. However, you can work around this by changing Excel’s default date system, using the TEXT function, or by using a custom format. Here are three methods you can use:
Learn how to perform date and time calculations, such as, compute cumulative hours, minutes, and seconds, find the difference between two distinct dates and/or times, add seconds, minutes, or hours to a given time. Extend days, months, or years to a specified date.
Date and time can be easily inserted into your excel workbook. Learn how to convert dates and times to serial numbers and perform operations on those numbers.
One limitation of Excel’s validation feature is that it does not allow you to dynamically update the list that serves as the validation source. Imagine how convenient it would be if you could enter a new value in a validated cell and have it automatically added to the list. This is achievable, as we will show you in the following sections.
Most Excel spreadsheets contain formulas. Sometimes you may want to force only the result of a formula to occupy a cell, instead of leaving the formula in place, where it will change if/when the data it references changes.
You can use the SUBTOTAL function to calculate subtotals in a list or table of data. It can perform various functions, such as SUM, AVERAGE, COUNT, MAX, and MIN, while ignoring (or including) hidden rows or filtered-out values.
Wouldn’t it be great if you could identify the subtotals in your worksheets so that you can find them easily? With the technique in this section, you can.
In this tutorial, we will use Excel’s subtotal capability to create subtotal values for the sorted categories. You can quickly create subtotals by using the Subtotal command on the Data tab. This command inserts subtotals for each group of data in your worksheet, based on a column that you specify.
If you are working with XML data in Excel, you might encounter a situation where you cannot save or export your data as an XML file. This can happen if the XML maps in your workbook are not exportable. In this tutorial, we will explain what causes this issue and how to fix it.
Excel supports importing and exporting data as XML files, which can be useful for sharing data with other applications. In this tutorial, we will show you how to export data as an XML file in Excel using the following steps:
