Hello,

I have problem with @formatDateTime forumala in compose action. I need to format date to supported flow format.

I tried these variants:

"@formatDateTime(‘custom_date_column’, 'o')"

"@formatDateTime(‘custom_date_column’)"

"@formatDateTime(concat(formatDateTime(‘custom_date_column’,'yyyy-MM-ddThh:mm:ss'),'-3:00'),'d/MM/yyyy hh:mm tt')"

"@formatDateTime(‘custom_date_column’,'yyyy-MM-dd hh:mm:ss')"

And in all variants, I receive error

'In function 'formatDateTime', the value provided for date time string (‘custom_date_column’ was not valid. The datetime string must match ISO 8601 format.'.

Maybe someone have ideas how to format date column from SharePoint Online list?

Hi @Mumbrasas,

Simply input the column name with the FormatDateTime function from SharePoint online list would not work here.

As the function is used under Microsoft Flow, we should use the Triggers/Actions and the related part from the them to identify the corresponding columns.

For example, here we take use of the When a New Item is created as the Flow trigger, then we need to use the EndTime value from the SharePoint list, we should write the formula under Compose Action as below:

"@formatdatetime(triggerBody()?['EndTime'],'yyyy-MM-ddThh:mm:ss')"

Mostly this is not so easy for end users to handle, so I would share a little tricks to find the content part:

1. Add a Compose Action after the trigger/Action, then specify the Compose input with the following format:

"@formatdatetime( ,'yyyy-MM-ddThh:mm:ss')"

2. Click at the first parameter part of the formatdatetime, then choose the corresponding dynamic content, save it,

3. Microsoft Flow won't save successfully, and would notify the error message of validation failed,which then we may find the corresponding part for the input,

4. Copy and paste the corresponding data within the braces @{ } into the function first parameter, then save the flow

Adding screenshots as reference:

Hope this helps,

Regards

This works for me, however I am only able to use it once.

I have a start and end date on my list, where I add 2 separate "Compose" actions, it ignores the second one.

How can I have both working ?

Not sure if this is your issue, but i renamed my Compose titles to be 'First Day' and 'Last Day' and they then both showed up as individual outputs for selection.

I cannot get this to work in my flow, i am trying to convert a US date format into an Australian date format with no success using the above fix. Any advice would be greatly appreciated.

Keeps emailing me like this, the bold part is my column name in my SharePoint list.

Start date: @{formatdatetime(@{triggerBody()?['Leave_x0020_start_x0020_date']},'dd/MM/yyyy')}

As per the instructions above, i think your problem is you need to remove the @{} symbols. I think you'll find you need your function to look something like this.

"@formatdatetime(triggerBody()?['Leave_x0020_start_x0020_date'],'dd/MM/yyyy')"

I actually ended up using @addhours so that i could manipulate for DLS. My code is below

"@addHours(triggerBody()?['Start_x0020_Date'],11,'dd/MM/yyyy-HH:mm')"

My Condition
if(greater(length(actionOutputs('DueDate')),0),formatDateTime(outputs('DueDate'),'yyyy-MM-dd'),''), works perfectly for valid date value, but for empty value it is no working.
The condition above mentioned getting fail if the value is empty

if(equals(empty(actionOutputs('DueDate')),false),formatDateTime(outputs('DueDate'),'yyyy-MM-dd'),''), is also generating the error :
In function 'formatdatetime', the value provided for date time string '' was not valid. The datetime string must match ISO 8601 format.'.
which hould not be the case for False condition.
Please suggect the solution.I am applying substring method to get the date.

Need to pass the null / empty string value to the date.
