Update Excel Row by DATE key column

[Sbence]

I'd like to update an Excel table based on the key column which is a DATE. I know Excel stores date as int, but how should I supply the parameter to the Excel Update Row connector?

Hi @Sbence 

I never tried to use an actual date, but I think if you pass the date formatted the same way as it is on Excel, then you'll be able to search for it. 

Ideally, you should use strings or better yet numbers to avoid issues, but if you want dates, then we can try this, and if it doesn't work, we can dig-in a little bit further.

Thanks, I've tried it, doesn't work this way. It has to be numeric

HI @Sbence 

You can calculate the number. The number 1 is January 01 1900 so we need to check the difference in seconds since that date until today. This is the value that you can send to Excel.

There is no easy way to do a difference between 2 dates, but there's another thread that can help you:

Yeah, each and every example shows how to calculate the DATE value from the INT (as stored in Excel), but not the opposite. And I'd like to avoid to loop through all the rows in flow

I couldn't find a general solution. I work with dates in 2020 only so I use this workaround

add(43830, dayOfYear(date_to_look_for)))
