What is the easiest way to convert a Julian date to a Gregorian date in Excel. I need some easy steps that I can try on my number of sheets. I have a vast database and I do not want to use any addin for the same.

You cannot do that without a add-in. You have to download and install a CalDate.xla called addin for the same. Once installed, a host of new features available to the user to calculate with dates, by overcoming the limitations of Excel for dates prior to 1900. These commands allow to convert a Julian date number written in text format. There are many more other things that you can try out. And remember there is no issue with the addin compatibility.
