ExcelExport | Classes to generate Excel/CSV Report in ASP.NET Core | CSV Processing library

I have 2 forms, one is the main one and the other one opens in a modal window. I need my second form to get the company session value (AIGN_EMP_ID), however, I don't know how to send this value when I call my form from the Context.

I downloaded the data and read by StringBuilder and achieved this result (The content of my StringBuilder)

I have a Kendo grid that uses Export-to-excel and Export-to-pdf.

One particular column consists of data with padded zeros (so that column sorting works). Then, this column uses a template to display the data without the padded zeros (a business requirement). This is perfect for the grid.

Now, the export functions do not export the template, they export the underlying data (this is documented in the Known Limitations). So my exports show the data with padded-zeros. But... I need to show the data without padded zeros. So I have been looking for a workaround.

Workaround attempt A) I created two columns padded and non-padded. The idea was this: Column i/ Data = padded; Grid view = non-padded; do not export. Column ii/ Data = non-padded; Grid view = hidden; export.

However, this doesn't work for two reasons. Column i/ columns: exportable: { pdf: false, excel: false } doesn't actually seem to work(!!!) Column ii/ This isn't legal anyway. If you hide the data in the grid you can't export it anyway.

Workaround attempt B) In the excelExport() function I did this:

i am trying to export data from my table to excel file using php excel library, my controller is like below:

I am writing C# code in which at the end I would want to export the resulting array to Excel. For this I looked up example codes to run first mock results to then use for my code. I tried implementing the codes using Interop Excel and while the code does run, can open/create a workbook, open/create a worksheet, rename worksheets, save the results down I cannot alter the cells. Neither value changes nor formatting changes work for me. It saves down a blank Excel file with the changes to the worksheets lets say.

Please see below the example codes I tried to run: I am using Rider but tried the results and failed in Visual Studio as well. Also tried from multiple computers and didn't work. .NET framework is 4.0.3 and the Interop package installed is the most recent 15.0.4795 (while also Microsoft Office Core is installed with the most recent 15.0.0 version). CSV writing did work (see the commented part in the first snippet).

I do not know what else to try, if I can give further context I am very happy to. Thank you for your help!

I'm facing a problem and I can't find a solution for it. I make a couple auf AJAX requests in my project and all work fine. But now, this AJAX request (build as the other ones) doesn't work.

The below code works fine with apache poi version 4.0.1 but after upgrading apache poi to the latest versions (version 4.1.2 or version 5.0.0) the xls file generated is corrupted and when i try to open it i cannot find any data inside. (the size of the xls file after upgrading the poi.jar was updated from 4KO to 0KO.)

There is a red underlined with the message: Incompatible types. Required: ...model.Constants Found: java.util.Optional on jpa findById method.

I use findById is here:

I have a working html/js datatable example jsfiddle that has two working buttons for exporting data; excel and csv. I declare my datatable like so:
