After importing data, it’s not uncommon to want to clean up and normalize data values, especially text fields that may have all types of inconsistencies. Unfortunately, Airtable doesn’t support in-place transformations where formulas can be applied to modify the field contents of all cells.
This is where the Field Tweaker script block can help. It supports in-place text transformations including upper case, lower case, and title case modifications across all records for select fields. The script is published below and this base provides a simple sales table to experiment with and also includes the script block.
