Extend supported extensions list Leave feedback
On this page
This method can be used when for some reason files have non-standard extensions or if its format is supported, but not pre-configured. For instance, all kinds of plain text files (batch, command files, etc.) could be opened. In this case you do not need to create your own format handler. As it is shown below, you can add file extension (e.g. “.dump”) as being handled by the same DocumentFormatInstance as all plain text files:
from groupdocs.redaction import Redactor
from groupdocs.redaction.configuration import RedactorConfiguration
from groupdocs.redaction.options import SaveOptions
from groupdocs.redaction.redactions import ExactPhraseRedaction, ReplacementOptions
def extend_supported_extensions_list():
# Add the .dump format to the list of supported formats, handled as plain text
config = RedactorConfiguration.get_instance()
settings = config.find_format(".txt")
settings.extension_filter = settings.extension_filter + ",.dump"
# Specify the redaction options
repl_opt = ReplacementOptions("[redacted]")
ex_red = ExactPhraseRedaction("dolor", repl_opt)
# Load the document with the newly supported extension
with Redactor("./sample.dump") as redactor:
# Apply the redaction
redactor.apply(ex_red)
# Save the redacted document
save_options = SaveOptions()
save_options.add_suffix = True
save_options.rasterize_to_pdf = True
save_options.redacted_file_suffix = "redacted"
result_path = redactor.save(save_options)
print(f"Document redacted successfully.\nCheck output in {result_path}.")
