How to show time with milliseconds in Excel?
For example a recorded time contains milliseconds, such as 10:33:50.235. When I type this time into a cell in Excel, the time shows as 33:50.2. After changing to the time format, the time shows as 10:33:50 AM with milliseconds disappearing. Is there any way to show time normally with remaining milliseconds in Excel? Yes, the following method will help you solve it easily.

This method will walk you through creating a custom time format to show time with milliseconds in Excel. Please do as follows:

2. In the opening Format Cells dialog box, go to Number tab, click to highlight the Custom in the Category box, and then type the format code hh:mm:ss.000 into the Type box.

Tip: Save the formatted time as Auto Text entry, and reuse its formatting in future easily
Normally we can apply custom format for cells with adding custom format code in the Format Cell dialog box in Excel. However, this custom format code is only saved in this workbook, and we can’t apply the custom format in other workbooks directly. Kutools for Excel’s AutoText utility enables us to save a formatted data/cell as an Auto Text entry, so that we can copy its custom format to other ranges of any workbooks directly.
