Ensure Privacy by Redacting your Classified Data

GroupDocs.Redaction for Java library empowers developers to redact text and images from supported documents by employing a variety of redaction types. To use our Redaction API is simple and straight forward.

The following code example uses a tabular document such as Microsoft Excel spreadsheet where the scope of redaction can be limited to a specific worksheet and/or column. It uses filters to redact the second column with emails on a worksheet “Customers”, leaving all other emails untouched in the document.

// Create an instance of Redactor class
final Redactor redactor  = new Redactor("sample.xlsx");
    CellFilter filter = new CellFilter();
    Pattern expression = Pattern.compile("^\\w+([-+.']\\w+)*@\\w+([-.]\\w+)*\\.\\w+([-.]\\w+)*$");
    // Apply redaction
    RedactorChangeLog result = redactor.apply(new CellColumnRedaction(filter, expression, new ReplacementOptions("[customer email]")));
    if (result.getStatus() != RedactionStatus.Failed)
        SaveOptions so = new SaveOptions();
finally { redactor.close(); }
