Implementation Guide

Let’s break down the implementation into sections based on specific functionalities.

Load and Edit DSV Document

Overview: This feature allows you to load a CSV file and perform text manipulations easily.

  1. Loading the Document:

    string inputFilePath = @"YOUR_DOCUMENT_DIRECTORY\sample.csv";

using (Editor editor = new Editor(inputFilePath))
{
    // Load options are not required here.
}

  2. Editing Content: Create edit options to specify delimiters and data treatment preferences:

    Options.DelimitedTextEditOptions editOptions = new DelimitedTextEditOptions(",")
{
    ConvertDateTimeData = false,
    ConvertNumericData = true,
    TreatConsecutiveDelimitersAsOne = true
};

  3. Applying Changes: Load the document into an editable format and apply your text replacements:

    EditableDocument beforeEdit = editor.Edit(editOptions);

string updatedTextContent = beforeEdit.GetContent()
                                     .Replace("SsangYong", "Chevrolet")
                                     .Replace("Kyron", "Camaro");

List<IHtmlResource> allResources = beforeEdit.AllResources;
EditableDocument afterEdit = EditableDocument.FromMarkup(updatedTextContent, allResources);

  4. Disposal: Always ensure to dispose of the initial editable document instance manually:

    beforeEdit.Dispose();

Save Edited Document as CSV

Overview: After editing, you can save your document back in CSV format with specified options.

  1. Specify Save Options: Configure delimiter and encoding settings for saving:

    Options.DelimitedTextSaveOptions csvSaveOptions = new DelimitedTextSaveOptions(",")
{
    Encoding = System.Text.Encoding.UTF8
};

  2. Saving the Document: Use the Editor instance to save changes:

    string outputCsvPath = Path.Combine(@"YOUR_OUTPUT_DIRECTORY", "editedDocument.csv");

using (Editor editor = new Editor(inputFilePath))
{
    EditableDocument beforeEdit = editor.Edit(new DelimitedTextEditOptions(","));

    string updatedTextContent = beforeEdit.GetContent()
                                         .Replace("SsangYong", "Chevrolet")
                                         .Replace("Kyron", "Camaro");

    List<IHtmlResource> allResources = beforeEdit.AllResources;
    EditableDocument afterEdit = EditableDocument.FromMarkup(updatedTextContent, allResources);

    editor.Save(afterEdit, outputCsvPath, csvSaveOptions);

    beforeEdit.Dispose();
    afterEdit.Dispose();
}

Save Edited Document as TSV

Overview: Similar to saving as CSV, but with tab-delimited format.

  1. Set TSV Options: Configure the delimiter and trimming options:

    Options.DelimitedTextSaveOptions tsvSaveOptions = new DelimitedTextSaveOptions("\t")
{
    TrimLeadingBlankRowAndColumn = false,
    Encoding = System.Text.Encoding.UTF8
};

  2. Saving as TSV: The process mirrors saving as CSV, with changes in save options:

string outputTsvPath = Path.Combine(@"YOUR_OUTPUT_DIRECTORY", "editedDocument.tsv");

using (Editor editor = new Editor(inputFilePath))
{
    EditableDocument beforeEdit = editor.Edit(new DelimitedTextEditOptions(","));
    
    string updatedTextContent = beforeEdit.GetContent()
                                         .Replace("SsangYong", "Chevrolet")
                                         .Replace("Kyron", "Camaro");

    List<IHtmlResource> allResources = beforeEdit.AllResources;
    EditableDocument afterEdit = EditableDocument.FromMarkup(updatedTextContent, allResources);
    
    editor.Save(afterEdit, outputTsvPath, tsvSaveOptions);

    beforeEdit.Dispose();
    afterEdit.Dispose();
}

Save Edited Document as Spreadsheet (e.g., XLSM)

Overview: Convert and save your edited document into a binary spreadsheet format.

  1. Configure Spreadsheet Options: Determine the output file format:

    Options.SpreadsheetSaveOptions cellsSaveOptions = new SpreadsheetSaveOptions(SpreadsheetFormats.Xlsm);

  2. Saving as XLSM: Utilize similar steps to previous save operations, focusing on spreadsheet formats:

    string outputCellsPath = Path.Combine(@"YOUR_OUTPUT_DIRECTORY", "editedDocument.xlsm");

using (Editor editor = new Editor(inputFilePath))
{
    EditableDocument beforeEdit = editor.Edit(new DelimitedTextEditOptions(","));

    string updatedTextContent = beforeEdit.GetContent()
                                         .Replace("SsangYong", "Chevrolet")
                                         .Replace("Kyron", "Camaro");

    List<IHtmlResource> allResources = beforeEdit.AllResources;
    EditableDocument afterEdit = EditableDocument.FromMarkup(updatedTextContent, allResources);

    editor.Save(afterEdit, outputCellsPath, cellsSaveOptions);

    beforeEdit.Dispose();
    afterEdit.Dispose();
}
