Description

CSVProcess reads an input csv by reading each line, filters the rows based on a condition, modifies the values, and writes the value. The function is applicable to only arrayofjavaarray and arrayofCFarray output formats.

Returns

None

History

ColdFusion (2025 release): Added the function.

Syntax

CSVProcess(filePath,rowProcessor,rowFilter[,csvFormatConfiguration])

CSVProcess(filePath,rowProcessor,rowFilter[,csvFormatConfiguration])

Parameters

Example 3

Using nullstring in the struct

Example 3

Using csvformatconfiguration={"quoteMode":"ALL","quotecharacter":"'"}

valuesProcessed = 0;
