The Gantt component allows exporting links, tasks and resources into Primavera P6.
To export data from the Gantt chart to Primavera P6, do the following:
gantt.plugins({
export_api: true
});
If you use the Gantt version older than 8.0, you need to include the https://export.dhtmlx.com/gantt/api.js on your page to enable the online export service, e.g.:
<script src="codebase/dhtmlxgantt.js"></script>
<script src="https://export.dhtmlx.com/gantt/api.js"></script>
gantt.exportToPrimaveraP6();
The method will send a request to the remote service, which will either output an XML Project file or return an url to download a generated file.

The response will contain a JSON of the following structure:
{
data: {},
config: {},
resources: [],
worktime: {}
}
The exportToPrimaveraP6() method takes as a parameter an object with a number of properties (all of the properties are optional):
gantt.exportToPrimaveraP6({
name:'custom.xml'
});
gantt.exportToPrimaveraP6({
auto_scheduling: false
});
gantt.exportToPrimaveraP6({
skip_circular_links: false
});
gantt.exportToPrimaveraP6({
project: {
'Author': 'I am!',
'MinutesPerDay': function () {
return gantt.config.hours_per_day * 60;
}
}
});
The properties of this object correspond to the appropriate properties of the Project entity. The list of supported properties can be found here. The properties may contain either fixed values or functions that will be executed when export is called.
gantt.exportToPrimaveraP6({
tasks: {
'StartVariance': function (task) {
if (task.startVariance)
return task.startVariance;
else
return 0;
},
'PercentWorkComplete': function (task) {
return (task.progress + 0.1);
},
'Custom': function (task) {
return 'Custom value';
},
'Custom 2': 'My Custom value'
}
});
The properties of this object correspond to the appropriate properties of the Task entity, here is a list of supported properties. The properties may contain either fixed values or functions that will be called for each task in the dataset when export is called.
It is expected that the start_date and end_date properties will be specified in the format which includes both the date and time (%d-%m-%Y %H:%i).
const customData = {
"data": [
{ "id": "10", "text": "Project #5", "start_date": "01-04-2025 00:00",
"duration": 3, "order": 10, "progress": 0.4, "open": true,
"end_date": "04-04-2025 00:00", "parent": 0
},
{ "id": "1", "text": "Task #67", "start_date": "02-04-2025 00:00",
"duration": 2, "order": 10, "progress": 0.6, "parent": "10",
"end_date": "04-04-2025 00:00"
},
{ "id": "2", "text": "Task #89", "start_date": "01-04-2025 00:00",
"duration": 2, "order": 20, "progress": 0.6, "parent": "10",
"end_date": "03-04-2025 00:00"
},
],
"links": [
{ "id": 1, "source": 1, "target": 2, "type": "1" },
]
}
gantt.exportToPrimaveraP6({
data: customData
});
Related sample: Gantt. Export custom data
gantt.exportToPrimaveraP6({
callback: function(res){
alert(res.url);
}
});
gantt.exportToPrimaveraP6({
resources: [
{"id":"1","name":"John","type":"work"},
{"id":"2","name":"Mike","type":"work"},
{"id":"3","name":"Anna","type":"work"}
]
});
Possible resource types are "work", "cost", "material". Resource assignments are specified using the ResourceAssignments property of the tasks configuration:
var users = [// resources
{key:'0', label: "N/A"},
{key:'1', label: "John"},
{key:'2', label: "Mike"},
{key:'3', label: "Anna"}
];
gantt.exportToPrimaveraP6({
resources: users
.filter(function(u){
if(u.key === '0')//skip the default option
return false;
return true;
})
.map(function(u){
return {
id: u.key,
name: u.label,
type: "work"
};
}),
tasks: {
ResourceAssignments: function(task){ return task.user; } }
});
The ResourceAssignments property is set as a function that takes the task object as a parameter and returns either a string/number value or an array of string/number values:
tasks: {
ResourceAssignments: function(task){
return [task.user, task.office];
}
}

});
In order to convert an XML or XER file, you need to send the following request to the export service:
The request parameters are:
For example:
<form action="https://export.dhtmlx.com/gantt" method="POST"
enctype="multipart/form-data">
<input type="file" name="file" />
<input type="hidden" name="type" value="primaveraP6-parse">
<button type="submit">Get</button>
</form>
Alternatively, you can use the client-side API, like this:
gantt.importFromPrimaveraP6({
data: file,
taskProperties: ["Notes", "Name"],
callback: function (project) {
if (project) {
gantt.clearAll();
if (project.config.duration_unit) {
gantt.config.duration_unit = project.config.duration_unit;
}
gantt.parse(project.data);
}
}
});

Where file is an instance of File which should contain either an XML or XER Project file.
gantt.importFromPrimaveraP6 requires HTML5 File API support.
The response will contain a JSON of the following structure:
{
data: {},
config: {},
resources: [],
worktime: {}
}
To set an expected duration unit, the durationUnit ("minute", "hour", "day", "week", "month", "year") string can also be sent to the server.
<form action="https://export.dhtmlx.com/gantt" method="POST"
enctype="multipart/form-data">
<input type="file" name="file" />
<input type="hidden" name="type" value="primaveraP6-parse">
<input type="hidden" name="data"
value="{ \"durationUnit\": \"hour\" }" />
<button type="submit">Get</button>
</form>
or
gantt.importFromPrimaveraP6({
data: file,
durationUnit: "hour",
callback: function(project){}
});
To get project fields, the projectProperties input with an array of necessary fields can be sent to the server. It extracts arbitrary properties of the Project entity into the config property of the output. Here is the list of supported properties.
<form action="https://export.dhtmlx.com/gantt" method="POST"
enctype="multipart/form-data">
<input type="file" name="file" />
<input type="hidden" name="type" value="primaveraP6-parse">
<input type="hidden" name="data"
value="{ \"projectProperties\": [\"Author\", \"Title\"] }" />
<button type="submit">Get</button>
</form>
or
gantt.importFromPrimaveraP6({
data: file,
durationUnit: "hour",
projectProperties: ["Author", "Title"],
callback: function(project){
var config = project.config;
alert(config.$custom_properties.Author);
}
});
To get task fields, the taskProperties input with an array of necessary fields can be sent to the server. It extracts arbitrary properties of the Task entities. Here is the list of supported properties:
<form action="https://export.dhtmlx.com/gantt" method="POST"
enctype="multipart/form-data">
<input type="file" name="file" />
<input type="hidden" name="type" value="primaveraP6-parse">
<input type="hidden" name="data"
value="{ \"taskProperties\": [\"Contact\", \"Priority\"] }" />
<button type="submit">Get</button>
</form>
or
gantt.importFromPrimaveraP6({
data: file,
durationUnit: "hour",
taskProperties: ["Contact", "Priority"],
callback: function(project){
var config = project.config;
alert(config.$custom_properties.Author);
gantt.parse(project.data);
}
});
gantt.attachEvent("onTaskLoading", function(task) {
if (task.$custom_data) {
task.contact = task.$custom_data["Contact"];
task.priority = task.$custom_data["priority"];
delete task.$custom_data;
}
return true;
});
The following logic allows you to obtain the task type: the tasks with the Project type have the Summary: "1"
property, and the tasks with the Milestone type have the Milestone: "1"
property. We need to import the data with these properties and then set the task type depending on these properties.
The call of the import function will look like this:
gantt.importFromPrimaveraP6({
data: file,
taskProperties: [
"Summary",
"Milestone",
],
callback: function (project) {
if (project) {
console.log(project)
gantt.clearAll();
if (project.config.duration_unit) {
gantt.config.duration_unit = project.config.duration_unit;
}
console.log('import: ', project.data);
gantt.parse(project.data);
}
}
});
After that you can convert the types of tasks based on the received properties as follows:
gantt.attachEvent("onTaskLoading", function (task) {
if (task.$custom_data) {
if (task.$custom_data.Summary == "1") {
task.type = "project";
}
if (task.$custom_data.Milestone == "1") {
task.type = "milestone";
}
// delete task.$custom_data;
}
return true;
});

There are two API endpoints for the Primavera P6 export/import services:
The endpoint can be specified by the server property of the export configuration object:
gantt.importFromPrimaveraP6({
server:"https://export.dhtmlx.com/gantt",
data: file,
callback: function(project){
// some logic
}
});
If no endpoint is specified, https://export.dhtmlx.com/gantt is used by default. The following call is equivalent to the one above:
gantt.importFromPrimaveraP6({
data: file,
callback: function(project){
// some logic
}
});
In order to export or import large projects that exceed the 4MB limit, the second endpoint can be used:
gantt.importFromPrimaveraP6({
server:"https://export.dhtmlx.com/gantt/project",
data: file,
callback: function(project){
// some logic
}
});
It allows sending requests up to 40MB in size and supports Primavera P6 exports and imports. It can be used for Primavera P6 exports only.
Any other methods, for example, gantt.exportToPDF({server:"https://export.dhtmlx.com/gantt/project"}) should return a server error.
