Filter data (Excel)

I have file Detail as below.
Datail Send data.xlsx (13.4 KB)

I want read column D for day round soon.
Example now 6/1/2022 —> next round = 12/1/2022
and read data in column E for filter data (filter date in column issue Date by condition date<25 Dec [red text] in file input)

File Input =
input.xlsx (9.8 KB)

Condition filter in file input :

  1. Column Status = Complete
  2. Column Count >= 15
  3. Column Issue Date <= 25/12/2021 (In B.E. 25641225)

after filter data in file input —> copy data to column in same sheet name.

File output = output.xlsx (19.5 KB)

*remark : Real data have about 30,000 rows

Please guide me about it.

Hi @fairymemay ,

Can we know what is the Column "Issue Date" in input.xlsx file.

As we have to Compare the Date i.e according to your input example 25 Dec with 25641225

What is '25641225' ? Date ? Is it some other format ? Binary ?


25641225 mean 2564 = year (in Buddhist era) , 12 = month , 25 = date

Buddhist era = Christian era + 543 (2564 = 2021 + 543)

If I want fix column name because In future if change column , I don’t want change code So I will create file config for set number column as below.
Config.xlsx (9.6 KB)

Please guide me for apply it.

Hi @fairymemay ,

I was able to Develop a workflow to generate the Output Required. However, there are a Few things to Consider/Give Importance to.

  1. The input.xlsx file contains a Duplicate Column Name, we won’t be able to read it Diectly. Hence, I have used a Snippet that Changes the name of the Duplicate Column.

The Name of the Second Status Column will be Changed to Status (1) by the Snippet.

  1. The Config file is modified and used Separately, Not along with other Configurations. This Config file should only be used to Read the Column Names of Input Excel and Output Excel.
    (Not sure whether this is the Expected Format that was desired)

  2. We perform the Filter operation on the InputDT based on the Conditions Provided with a Linq expression as below :

InputDT.AsEnumerable.Where(Function(x)x("Status (1)").ToString.ToLower.Equals("complete") and Cint(x("Count")) >= 15 and DateTime.ParseExact(x("Issue Date").ToString.Trim,"yyyyMMdd",System.Globalization.CultureInfo.InvariantCulture).AddYears(-543)<= ApproveDate).ToArray

The AddYears(-543) is done to get the Current Era year.

  1. The Output Excel Template is maintained in the Template folder. So that each time, the Output Template is copied to maintain the Output format.

  2. To Generate the Output Data, we Iterate over the Filtered Rows that Satisfies the Condition Specified and add it to the Output Datatable which is Created using the Column names in Config.

Below is the workflow. Please do check and let us know if is not the Expected Solution.

@supermanPunch File output not correct.
Now output Show as below.

But that true should show 2 rows (Mary, Jack) Because Issue Date > 25641225

And condition , If I don’t fix month=12 But I want check month now.

Remark : Real Data input have 30000 transaction , If I run it work slowly or not?

Thank you for your suggest.

Hi @fairymemay ,

According to your Initial Comparison logic, It should have been Issue Date <= Approve Date . Hence, the Output Result did not match.

We can Update the logic inside the Linq Expression as follows :

InputDT.AsEnumerable.Where(Function(x)x("Status (1)").ToString.ToLower.Equals("complete") and Cint(x("Count")) >= 15 and DateTime.ParseExact(x("Issue Date").ToString.Trim,"yyyyMMdd",System.Globalization.CultureInfo.InvariantCulture).AddYears(-543)>= ApproveDate).ToArray

It is Just a Change from <= to >= as highlighted below.

Yes, I couldn’t understand the Logic Straight away to decide which year it is to be taken in that Column. Hence, I made my own logic. We can Change it to Check by Current Month and Update the Year Accordingly.
Now, as far as I have understood, The Changes for that if Condition is as below :

Let me know if you’re unable to make these changes aand get the right output or if there is any incorrect logic.

    Please guide me about it.

  1. If I config file I want fix column name but I want fix number column in excel can it be possible?

Because I want use config same pattern (In organize).

    Example :
    input.xlsx (14.5 KB)
    Output.xlsx (28.5 KB)

Please guide me about it.

Thank you for your suggestion.

Hi @fairymemay ,
Can we know what is the Lot No. value to Compare with , and How to Compare it if the format is a different way?

Can you Explain in detail what do you mean by Fix Column Name in Number Column?

Do you want the Position of the Columns to be Kept as Specified in the Config File ? Eg : Campaign Period Column as 1st Column ?


  1. Lot No. = row that match date follow logic previous (same row Approve Date)
    I want keep Lot No in variable(string).

  2. Yes, Campaign Period Column as 1st Column , Lot send Column as 2rd Column , …

Thank you for your support me.

@supermanPunch Additional : I want keep lot No. that match in variable1 and Date Approve that match from Data ( Ex: 25641225 in variable2)

Please guide me more about it.

Hi @fairymemay ,

In the Config Excel file, I have added another Column which will be determining the Position of the Column in Excel.

Before Writing the Output Datatable, I am arranging the Columns using the Posiiton as shown below :

Also, I have Stored the Approve Date and Lot No. in variables.

Please do Check on the method and the Config file formats, and let us know if this is the Expected Output that you required. Below is the Updated Workflow.

I want output as below.

Please guide me about it.

Thank you for your support.

@supermanPunch I will waiting for your suggestion above requirements.

Hi @fairymemay ,

Apologies for the very late response, as I was busy in completing some tasks of mine.

I have updated the Workflow to meet your Expected Output.

I had to use an External Package to read only the Visible Sheets in Input Excel.

Also, the Logic remains the same, it’s just we need to loop through all the Visible Sheets to generate the correct output.

Also, The Lot Number is included in the Same Config Sheet. You can Keep it a Different Sheet if required and read the value from there.

Check below the Workflow and Let us know if it is not the Expected solution.
