Creating a Custom Export for use in the REIN Matrix system

MLS export files that are uploaded to Spark must be in a specific format in order to provide both accurate data and all possible fields.

Follow the instructions below to complete the one-time setup for Spark in the REIN Matrix system.  Contact us here if you have problems with the file setup and we'll be glad to help.

  • Hover your mouse over 'My Matrix' and select 'Settings'.

  • Click on 'Custom Exports' then click on 'Add Export'.

  • Name the export 'Spark'.

  • IMPORTANT: Verify toward the bottom that 'Label' and 'Comma' are chosen. The 'Label' button is TO THE RIGHT of the word 'Label'.
    Looks like this:      None ( )     Label (●)     Name ( )
    No need to enter a description.
  • Double-click on each of the following features individually (you can also click on each one and click 'Add'). Once you are done, the categories will appear on the right side of the window. The list is long but once this is set up in your MLS you'll never have to do it again.

How to Export your Data

  • Verify that the search you are exporting includes the sales/listings/rentals you want to put into the grid(s) of your appraisal report.

  • On the results page of your search choose the listings/sales/rentals you want included (using the check box to the left) or click 'All' if you want all of them.

  • Click 'Export' which is on the bottom row of buttons.

  • Verify the custom export you made is selected in the drop-down which should be 'Spark' then click 'Export'.

  • Save the file by whichever file name and into whichever folder you prefer (depending on browser settings you may not be given the option to choose the file name/location).

  • Now load Spark by going to and follow the steps.

Note: Spark can input a maximum of 30 properties for each grid (sales grid/listing grid/rental grid) and a maximum of 10,000 for your 1004MC files (Competing and/or Neighborhood File).

IMPORTANT FOR MULTI-FAMILY: Spark does not support multi-family in this MLS due to limitations in how this MLS exports multi-family data. However, there is a work-around to get some of the multi-family information into your report. Simply, export the information like normal and choose the 1004 form in Spark. Even though you chose 1004, Spark will recognize the multi-family data and load as much data as possible into your report given that Spark does not have full support or have access to all the multi-family data in this MLS. Keep in mind that some data, including individual unit information, will not be available and some property feature information (e.g. pools, fireplaces, etc) that works fine for SFR and Condos may not be exported from the MLS the same when it comes to multi-family. Be sure to verify all of the information.
