WriteDump
Last update:
May 18, 2026
Description
A function equivalent to the <cfdump> tag which can be used in <cfscript>.
Parameters
Same as <cfdump> tag.
Category
Function syntax
WriteDump (var, output, format, abort, label, metainfo, top, show, hide, keys, expand, showUDFs);See also
History
ColdFusion 11: Parameters passed to this function needs to be in a comma-separated format.
ColdFusion 9: Added this function.
Usage
You can call this function providing arguments as name-value pair or as positional arguments .For positional notations, the sequence must be followed exactly in the same manner as provided in the syntax. If you do not provide one of the parameters, use an empty string instead. This does not apply to Boolean values for which you must provide proper values even if you have to skip them.
Example 1
<cfscript>
myArr=listToArray("The,Quick,Brown,Fox,Jumps,Over,The,Lazy,Dog")
writeDump(var="#myArr#",format="text")

}
catch(Expression exception) {
WriteOutput("<p>An Expression exception was thrown.</p>");
WriteOutput("<p>#exception.message#</p>");
WriteLog(type="Error", file="myapp.log", text="[exception.type] #exception.message#");
}
</cfscript>Output

Real-world uses of the WriteDump function
Application development and debugging
Development teams building complex ColdFusion applications need comprehensive debugging capabilities to inspect variables, data structures, and application state during development and testing phases. Manual variable inspection through WriteOutput is time-intensive and incomplete. Complex data structures (structs, arrays, queries) are difficult to visualize and debug. Use WriteDump to instantly visualize any ColdFusion variable with complete structure details, data types, and nested relationships for rapid debugging.

</cfoutput>Production error logging and diagnostics
Production ColdFusion applications require comprehensive error logging and diagnostic capabilities for rapid incident resolution and system monitoring without impacting user experience. Standard error logging lacks detailed context about application state. Manual log parsing is time-consuming and incomplete. Production issues take 4-6 hours to diagnose due to insufficient diagnostic information. Use WriteDump to capture detailed application state, variable contents, and error context in production logs for comprehensive incident analysis.

</cfoutput>API development and integration testing
Development teams creating REST APIs and integrating with external services need comprehensive request/response inspection and data validation capabilities for reliable service delivery. API request/response debugging requires manual inspection of complex JSON structures. Integration testing lacks visibility into data transformation processes. Use WriteDump to inspect API payloads, validate data transformations, and capture integration points for comprehensive API testing and debugging.

</cfoutput>Database query analysis and performance tuning
Database administrators and developers need detailed query result inspection and performance analysis capabilities to optimize database interactions and ensure efficient data retrieval. Complex query results are difficult to analyze manually. Query performance bottlenecks are hard to identify without detailed result inspection. Database optimization takes weeks due to limited visibility into query execution. Use WriteDump to analyze query structures, inspect result sets, and capture query metadata for comprehensive database performance analysis.
