Convert PDF to csv using C#

Consider the LEADTOOLS Toolkit (https://www.leadtools.com/sdk/forms/invoice) which has features for the detection and extraction of text and numerical information from tabular forms with variable rows and columns.

You can see a video overview of these features here:

The code for creating master form would look something like this:

FormProcessingEngine processingEngine = new FormProcessingEngine();
FormPage formPage = new FormPage(1, 300, 300);
TableFormField tableField = new TableFormField();
tableField.Rules = TableRules.RowsLineSeparator;
// Create Columns
TextFormField column1 = new TextFormField();
column1.Name = "Status";
column1.Bounds = new LogicalRectangle(UpperLeftCornerX, UpperLeftCornerY, Width, Height, LogicalUnit.Pixel);
tableField.Columns.Add(new TableColumn(column1));
TextFormField column2 = new TextFormField();
column2.Name = "Panel Date";
column2.Bounds = new LogicalRectangle(UpperLeftCornerX, UpperLeftCornerY, Width, Height, LogicalUnit.Pixel);
tableField.Columns.Add(new TableColumn(column2));
// …
// Do For all Columns
formPage.Add(tableField);
//Add the page to the engine
processingEngine.Pages.Add(formPage);

Once you have a master form for the PDF with tables, you can perform recognition using code like the one described here:

Hi Rajkumar,

Try the "Spire" component in Nuget Package Manager. You can achieve your task I think. It may Help you. (Note : 100 % not sure.. Just try with that)
