Редактировать CSV в Java

// Load the CSV file into Editor with no extra loading options
Editor editor = new Editor("source.csv");

// Create edit options for delimited text and specify a mandatory separator in the constructor
DelimitedTextEditOptions editOptions = new DelimitedTextEditOptions(",");        

// Open input CSV document for edit — obtain an intermediate document, that can be edited
EditableDocument beforeEdit = editor.edit(editOptions);

// Grab CSV document content and associated resources from editable document
string content = beforeEdit.getContent();

// Send the content to WYSIWYG-editor, edit it there, and send edited content back to the server-side
// This step simulates a such operation
string updatedContent = content.replace("Cell Text", "Edited Cell Text");

// Grab edited content and resources from WYSIWYG-editor and create a new EditableDocument instance from it
EditableDocument afterEdit = EditableDocument.fromMarkup(updatedContent, null);

// Create save options for delimited text and specify a mandatory separator in the constructor
DelimitedTextSaveOptions saveOptions = new DelimitedTextSaveOptions(",");

// Save edited CSV document to the file
editor.save(afterEdit, "edited.csv", saveOptions);
