How to Filter Date Column with #N/A Value

Hi All,

My Scenario is to Filter the date column With #N/A Value and Update with 0.00.

Please find attached snipet:

I Used below code using Linq:
io_monthlyrollDT.Select(“3/31/2021=’#N/A’”).ToList().ForEach(Sub(row) row(“3/31/2021”)=“0.00”)

I am getting error like this:
RemoteException wrapping System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. —> RemoteException wrapping System.Data.SyntaxErrorException: Syntax error: Missing operand after ‘’’’ operator.
at System.Data.ExpressionParser.Parse()

It’s better to view your datatable, As I tried the same by keeping few #N/A and it is showing as empty insted of #N/A

So if you are getting the same in your case too, then use below expression

dt.AsEnumerable.Where(Function(row) String.IsNullOrWhiteSpace(row(“3/31/2021”).ToString.Trim)).ToList().ForEach(Sub(row) row(“3/31/2021”)="0.00")

This will result you as below

Hope this may help you

Thanks

Hi Srini,

I am getting the below error if i am using this query.
dt.AsEnumerable.Where(Function(row) String.IsNullOrWhiteSpace(row(“3/31/2021”).ToString.Trim)).ToList().ForEach(Sub(row) row(“3/31/2021”)=“0.00”)

RemoteException wrapping System.ArgumentException: Column ‘3/31/2021’ does not belong to table DataTable.

@surya_teja.k

In Read Range activity enable add headers

Or you can replace with index of the Column too

Hope this may help you

Thanks

Hi Srini,

Thanks for replying, i have used with index, i am not getting any error but upadate is not happening.
May i know how this value is getting filtered.
#N/A.

please find the query which is used in invoke code.
io_dt.AsEnumerable.Where(Function(row) String.IsNullOrWhiteSpace(row(7).ToString.Trim)).ToList().ForEach(Sub(row) row(7)=“0.00”)

please find the attached snipet for reference after running with index.

@surya_teja.k

Can you remove your filter and check
Also can you share your sample excel file to see the issue?

Thanks

Ya, its removed srini. there is no filter no w its just a filter syombol.

@surya_teja.k

Can you share where still #N.A is there?

Usally if you check the expression, as i told you before #N.A is showing as empty rows

so I placed string.IsNullOrWhiteSpace which will check for Null values

Hope this will understand, as I asked you if you can provide a sample excel, so that I can check the issue

Thanks

Thanks for replying.
Please find the sample excel.
Filter.xlsx (5.4 MB)

sheet1 contains which need to be filtred.
sheet2 contains output after filtering.

Thanks

@surya_teja.k

If you are using Invoke Code for the expression then make sure that your datatable argument is in/out and make sure you are passing the same datatable variable to write range activity

Still it is not updating then better share your xaml file with project.json file

Hope this may help you

Thanks

yes did the same, please find the same
Main.xaml (6.7 KB)
project.json (1.4 KB)
Thanks
surya

@surya_teja.k

The output of the invoke code is io_dt, but you are trying to write the old dt, replace dt as io_dt in Write range and see

Mark as solution if this helps

Thanks

How can we use io_dt its an invoke code argumet right?

I tried creating both variable and argument. but still didnt work can u share your xaml file?

@surya_teja.k

Can you try to use Workbook activities instead of Excel application scope activities and check
It’s working

Hope this may help you

Thanks

I tried same issue over there, please share a xaml file it will be helpful.

Thanks,

Hi Please check the workflow.

project.json (1.4 KB)
Main.xaml (9.3 KB)

and share the changes where i have to do.

Thanks
