In template documents, a
Data types of comma-separated values are determined automatically upon their string representations. So in template
documents, you can work with typed values rather than just strings. The engine is capable to automatically recognize
values of the following types:
Note that for automatic recognition of data types to work, string representations of comma-separated values should
be formed using invariant culture settings.
To override default behavior of CSV data loading, initialize and pass a Example:
Document doc = new Document(getMyDir() + "Reporting engine template - CSV data destination (Java).docx");
CsvDataLoadOptions loadOptions = new CsvDataLoadOptions(true);
loadOptions.setDelimiter(';');
loadOptions.setCommentChar('$');
loadOptions.hasHeaders(true);
loadOptions.setQuoteChar('"');
CsvDataSource dataSource = new CsvDataSource(getMyDir() + "List of people.csv", loadOptions);
buildReport(doc, dataSource, "persons");
doc.save(getArtifactsDir() + "ReportingEngine.CsvDataString.docx");
