UDataTableFunctionLibrary::FillDataTableFromJSONString

function Engine Blueprint Since unknown

#include "Kismet/DataTableFunctionLibrary.h"

Access: public Specifiers: staticBlueprintCallable

Description

Empties DataTable and repopulates it by parsing JSONString as JSON row data, optionally forcing a specific row struct for the import.

Caveats & Gotchas

• Editor-only (#if WITH_EDITOR); not available in packaged/runtime builds.
• Expects the same JSON shape UE produces when exporting a DataTable to JSON (an array of objects keyed by row name); hand-written JSON that doesn't match this shape will fail to import.

Signature

static bool FillDataTableFromJSONString(UDataTable* DataTable, const FString& JSONString, UScriptStruct* ImportRowStruct = nullptr);

Parameters

Name	Type	Description	Default
DataTable	UDataTable*	The table to empty and repopulate.	—
JSONString	const FString&	JSON text to parse as the table's new contents.	—
ImportRowStruct	UScriptStruct*	Optional row struct to force for the import; also makes the import fully automated with no dialogs.	nullptr

Return Type

bool

Example

Import JSON text into a table C++

const FString JSON = TEXT("[{\"Name\":\"Rifle\",\"Damage\":25,\"FireRate\":0.1}]");
UDataTableFunctionLibrary::FillDataTableFromJSONString(MyDataTable, JSON, FWeaponStatsRow::StaticStruct());
