Copy - Update excel data from Excel Online to a Share Point List

Hello community.

 

For days and days I have been trying to get this thing to work. But this still a pain in the neck.

 

Basically I am following this video to do it. and it is partially working. I am going to explain what is working and what is not working at all.

 

1. The rows limitation of 256. I had this error but was corrected using the pagination and increasing the threshold number up to 50000. BTW my excel file has 8,000 rows.

 

2. In my excel file I have a couple of Date columns in the following format "7/30/2015  15:56 PM". I am using this formula to convert those strings into a sharepoint date values but I am getting errors and the flow doesn't work

 

addDays('1899-12-30',int(tems('Apply_to_each')?['regularTime']),'yyyy-MM-dd').

 

In my Sharepoint point column I have the field "regularTime" as a single line of text. I have tried as a date format and didn't work. Also I have removed the Time portion and in Sharepoint it shows a day before or a day after. Weird and strange.

 

Could someone PLEASE point me in the right direction?

 

Thanks in advance.

    Hi @sajarac ,

     

    Tried the below.

    1) Set ISO 8601 in your Excel List Rows action

    2) Recommend using the Convert time zone action so you don't have to play around with expressions.  Change the source to your local region.

    Hey, @eric-cheng . Thank you very much for your prompt response. Your solution works FANTASTIC!!!!. Done at the first try.

    Silly question. In my excel table I have 4 columns with the same problem. Should I add 4 "Convert Time actions" or in the Base time I can add those 4 columns?

     

    Thanks again for your help.

     

    Regards

    Hi @sajarac ,

     

    Will need 4 actions.  Its simpler but less flexible.

    Hi @eric-cheng , sorry to bother you again. I have been trying to include the rest of the dates columns but for some reason the next column is causing error:

     

    Unable to process template language expressions for action 'Convert_time_zone_lastDirSyncTime' at line '1' and column '26998': 'In function 'converttimezone', the value provided for date time string '' was not valid. The datetime string must match ISO 8601 format.'.

     

    That column has empty values but the first date column also has some empty values but it is working fine. I have checked that column to see if has a different value from date but no.

     

    Any idea?

     

    Thanks in advance

    Hi @sajarac ,

     

    Can you provide a snippet of the date valuesnin the working and non working column?

     

    Is it formatted as a date in the Excel?

    Can you screenshot your 2 DateTime actions as well.
