This processor computes new columns using formulas based on other columns (like in a spreadsheet). The formula language provides:

  • Math functions

  • String manipulation functions

  • Date handling functions

  • Boolean and conditional expressions for rules creation

Usage examples

  • Compute a numerical expression: (col1 + col2) / 2 * log(col3)

  • Manipulate strings : toLowercase(substring(strip(mytext), 0, 7))

  • Create a rule-based column: if (width > height, "wide", "tall")
