This requires preloading CSV file content into memory but allows to edit any field at any moment. * Random read/write access to CSV fields based on object model (TCSVDocument class).

* Field-by-field building of CSV files using TCSVBuilder class. This helps to write CSV content directly to file and thus avoid using in-memory buffer.

* Both UTF-8 encoding and windows-xxx codepages can be used with CsvDocument library. The library uses ''string'' type for all string operations and will not do any encoding conversion for you.

* StringGrid-like field access with TCsvDocument.Cells[ACol, ARow]. Field access is safe, that means when you try to access non-existing field you do not get "Index out of bounds" exception, but get an empty string result. To distingush between empty and non-existing fields there are methods and properties like HasRow/HasCell and RowCount/ColCount. * StringGrid-like field access with TCsvDocument.Cells[ACol, ARow].
