Clovi's parsing algorithms for eligibility and historical data files are flexible, understanding over 150 variations of column names. However, if you still have a unique column name that you want to ensure is parsed, you can add it manually under Account > Data Import.
The Attribute is a Clovi-defined data attribute that belongs to a Participant and/or Measurement model. You can add/remove your own column name in the Column names to parse. Once you add it, press Enter and it will save. Once the mapping looks to your standard, you can proceed with uploading the Eligibility and/or Historical Data files.
