Need to hide sensitive data in your EDI files?

EDI File Scrubber provides a fast and easy way to hide sensitive data in EDI files.



Main Features

  • Scrubs any EDI file (X12 and EDIFACT)
  • Fast parsing and scrubbing speeds
  • Creates an EDI Document object after scrubbing is completed for easy access to EDI data
  • Option to scrub EDI data from the file system or in-memory strings


Sometimes there is a need to mask sensitive data in EDI files.  IDs, social security numbers, names and  addresses are just a few items that developers may want to hide before sending EDI files to other vendors.  The EDIFileScrubber allows developers to quickly do this without having to understand the X12 or EDIFACT standards.

For example, let’s take a simple X12 ISA segment

ISA*00*          *00*          *ZZ*ASHTB          *ZZ*01017          *040315*1005*U*00401*004075123*0*P*:~

After processing the EDI file any element could be masked using the EDI File Scrubber.  For example:

ISA*QQ*QQQQQQQQQQ*QQ*QQQQQQQQQQ*ZZ*ASHTB          *ZZ*01017          *040315*1005*U*00401*004075123*0*P*:~

As shown below we have just masked element 1,2,3 and 4 by replacing their values with the letter ‘Q’.  Notice that the lengths of the elements remain the same.  Developers can figure any element or composite element value to be masked.

Scrubbing from a File or In-Memory String

EDIFileScrubber can scrub files from the file system using the EDIFile property as well as from a string of EDI data using the EDIDataString property.

Auto Detection of Delimiters

EDIFileScrubber has a Delimiter property that can be set if these delimiters are known beforehand.  It also has a property called AutoDetectDelimiters.  By enabling this property EDIFileScrubber detects the special delimiter characters while scrubbing is being performed.  Parsing is then performed from this point as usual.

Accessing Scrubbed Data

Because EDIFileScrubber does not use any rules file, there is no validation on the EDI data.  More importantly there is no proper hierarchy data conforming to the EDI implementation guides as you would find in the EDIValidator component.  There is only one main loop containing all the scrubbed segments and elements that exist in the EDI file.  This gives developers the flexibility to consume this data however they please


// Create a new instance of EDIFileScrubber
EDIFileScrubber scrubber = new EDIFileScrubber

scrubber.AutoDetectDelimiters = true;

// Set the type of EDI file that you are about the scrub
scrubber.EDIFileType = FileType.X12; //Or FileType.EDIFACT

// Set the source of EDI data, whether you are scrubbing from an in-memory string or a file.  If you are scrubbing from a string then set the EDIDataString property to the EDI data
scrubber.EDISource = EDISource.File // Or EDISource.DataString

// Set the EDI file path to scrub
scrubber.EDIFile = "C:\\EDIFile.txt

// Set the scrubbing rule (s)

// Set element 0,1,2,3 of the ISA segment to be replaced by the character 'Q'
ScrubRule rule = new ScrubRule();
rule.SegmentName = "ISA";
rule.ReplaceCharacter = 'Q';
rule.ScrubPositions.Add(new ScrubPosition(0));
rule.ScrubPositions.Add(new ScrubPosition(1));
rule.ScrubPositions.Add(new ScrubPosition(2));
rule.ScrubPositions.Add(new ScrubPosition(3));

// Set composite element 0 element 0 of the SVC segment to be replaced by the character 'W'
ScrubRule rule2 = new ScrubRule();
rule2.SegmentName = "SVC";
rule2.ReplaceCharacter = 'W';
rule2.ScrubPositions.Add(new ScrubPosition(0,0));


// scrub the data
EDILightWeightDocument doc = scrubber.Scrub();
