Below are the instructions you need for the one-time setup of your export file in MARIS.

If, for any reason, you have trouble with the file setup below or with the data going into Spark, contact us here for assistance.

Creating a Custom Export for use in the MARIS 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 MARIS 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.
  • Click on each of the following categories individually and click 'Add' after each one. 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. *NOTE: All of these fields are required for Spark to work even if you don’t think you need them.

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).
