Signature	Description
`NormalizeOptionalRange(value: std::string_view, parameterName: std::string_view)` → `std::string`	Normalizes an optional range string, returning empty if blank. Throws CellsException if non-blank but not a valid range.
`NormalizeRequiredRange(value: std::string_view, parameterName: std::string_view)` → `std::string`	Normalizes a required range string, throwing if blank or invalid.
`TryNormalizeRange(value: std::string_view, normalized: std::string)` → `bool`	Attempts to normalize a range string. Returns true on success.
`NormalizeOptionalText(value: std::string_view)` → `std::string`	Normalizes optional text by trimming; returns empty if blank.
`NormalizeText(value: std::string_view, parameterName: std::string_view)` → `std::string`	Validates that a text value is non-null. Throws ArgumentNullException equivalent if the value is null. Returns the value as a string.
`ParseOperatorOrDefault(value: std::string_view)` → `FilterOperatorType`	Parses an operator string, defaulting to Equal on blank input.
`TryParseOperator(value: std::string_view, operatorType: FilterOperatorType)` → `bool`	Parses an operator string, returning false on unrecognized values.
`ToOperatorName(operatorType: FilterOperatorType)` → `std::string`	Converts a FilterOperatorType to its XML attribute name, or null/empty for Equal.
`CompareFilterColumns(left: Core::FilterColumnModel, right: Core::FilterColumnModel)` → `int`	Compares two filter columns by column index.
