Posted on by MJ_RT

Hello,

I have created a flow to import data from Excel to SharePoint List. this includes a date.

I have tried:

Excel field farmated as Date AND SP List formated as Date ==> Failed

Excel field farmated as General AND SP List formated as Date ==> Failed
Excel field farmated as Date AND SP List formated as Text ==> Succeed

Excel field farmated as Text AND SP List formated as Text ==> Succeed

The date now on SP List shows numbers in the format 44276 (field is a text field).
when I convert this to date using Datevalue or Text(datevalue the PowerApps lable shows wrong day and month and even the year is 44xx.

I would appreciate any help to transfer or convert it correctly into German date format (only date) dd.mm.yyyy

Regards,

Excel stores dates as the number of days since 01/01/1900. The whole number portion is the actual number of days and the decimal portion is the fractional number of days. so the calculation to convert it to a date looks like this.

DateAdd(DateTimeValue("1899-12-30 12:00:00 AM"),RoundDown(( Value(ExcelDate)* 86400),0), TimeUnit.Seconds)

You use 12/30/1899 because 1900 didn't have a leap day 2/29 and the count starts with 1/1 as the first day. So math is off by 2 if you use 1/1/1900 .

If your locale doesn't put it in German format automatically then you can force it with

Text(DateValue, ShortDateTime,"de-DE")

thanks, but where should this code go?

DateAdd(DateTimeValue("1899-12-30 12:00:00 AM"),RoundDown(( Value(ExcelDate)* 86400),0), TimeUnit.Seconds)

When you are displaying the date from Excel or saving it to SP. This will translate the serial date from Excel to an actual Date Time value.
