Formula

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")
