jfliistro after rereading your post I gather you wanted something free but if you free to look at and use our Replacement Cost Calculator free for 30 days. It will permit you to print a nice report as well as compute the valuation. The standalone version is $99 a year and permits you to print out the report. It is the same module that is included free with our PowerClaim XML estimating solution.
I do not think from your post you are interested in doing underwriting valuation reporting but we have a per use ($5 in lots of 20) or annual fee ($250) based web version that will permit you to do the same as with the stand alone but without installing any software plus you can attach digital photos and write an underwriting report by web to go along with the valuation report. The carrier/TPA or who ever can just log into the website and view or print your completed underwriting report including the photos.
While this can be viewed as a commercial you may be interested if you do many so you do not have to manually create your reports if you do many each year. Clearly the $99 is not a get rich scheme but it helps some look more profession and gives numbers that can be supported in a court of law in that the database comes directly out of the Craftsman Book Company National Building Cost manual.
Since you are new to CADO you may want to do a search because I remember there was some free Excel tool adjusters were sharing during the hurricanes but I just do not remember what it was for but it let you plug in numbers for some part of handling a claim. If I hear of something that is floating around that is free but could meet your needs I will post it.
Could you spell out in a little more detail what you want the Excel spread sheet to do for you because I am sure there is some that has created something like that but many use estimating software today that includes that reporting feature.
