app.vue

<template>
<div id="app">
        <ejs-treegrid ref='treegrid' :dataSource='data' height='220' childMapping='subtasks' :treeColumnIndex='1' :allowPaging='true' :pageSettings='pageSettings' :allowExcelExport='true' :toolbar='toolbarOptions' :toolbarClick='toolbarClick'>
            <e-columns>
                <e-column field='taskID' headerText='Task ID' width='90' textAlign='Right'></e-column>
                <e-column field='taskName' headerText='Task Name' width='160'></e-column>
                <e-column field='startDate' headerText='Start Date' width='90' format="yMd" textAlign='Right'></e-column>
                <e-column field='duration' headerText='Duration' width='80' :visible='false' textAlign='Right'></e-column>
            </e-columns>
        </ejs-treegrid>
</div>
</template>
<script>
import Vue from "vue";
import { TreeGridPlugin, Page, Toolbar, ExcelExport } from "@syncfusion/ej2-vue-treegrid";
import { sampleData } from "./datasource.js";

Vue.use(TreeGridPlugin);

export default {
  data ()  {
    return {
      data: sampleData,
      toolbarOptions: ['ExcelExport'],
      pageSettings: { pageSize: 7 }
    };
  },
  methods: {
      toolbarClick(args) {
        if (args['item'].text === 'Excel Export') {
          let excelExportProperties = {
            includeHiddenColumn: true
          }
          this.$refs.treegrid.excelExport(excelExportProperties);
        }
    }
  },
  provide: {
      treegrid: [ Page, Toolbar, ExcelExport ]
  }
}
</script>

Show or hide columns on exported excel

You can show a hidden column or hide a visible column while printing the treegrid using toolbarClick and excelExportComplete events.

In the toolbarClick event, based on args.item.text as Excel Export. We can show or hide columns by setting column.visible property to true or false respectively.

In the excelExportComplete event, We have reversed the state back to the previous state.

In the below example, we have Duration as a hidden column in the treegrid. While exporting, we have changed Duration to visible column and StartDate as hidden column.

<div id="app">
        <ejs-treegrid ref='treegrid' :dataSource='data' height='220' childMapping='subtasks' :treeColumnIndex='1' :allowPaging='true' :pageSettings='pageSettings' :allowExcelExport='true' :toolbar='toolbarOptions' :toolbarClick='toolbarClick' :excelExportComplete='excelExportComplete'>
            <e-columns>
                <e-column field='taskID' headerText='Task ID' width='90' textAlign='Right'></e-column>
                <e-column field='taskName' headerText='Task Name' width='160'></e-column>
                <e-column field='startDate' headerText='Start Date' width='90' format="yMd" textAlign='Right'></e-column>
                <e-column field='duration' headerText='Duration' width='80' :visible='false' textAlign='Right'></e-column>
            </e-columns>
        </ejs-treegrid>
</div>
</template>
<script>
import Vue from "vue";
import { TreeGridPlugin, Page, Toolbar, ExcelExport } from "@syncfusion/ej2-vue-treegrid";
import { sampleData } from "./datasource.js";

Vue.use(TreeGridPlugin);

export default {
  data ()  {
    return {
      data: sampleData,
      toolbarOptions: ['ExcelExport'],
      pageSettings: { pageSize: 7 }
    };
  },
  methods: {
      toolbarClick(args) {
        if (args['item'].text === 'Excel Export') {
          this.$refs.treegrid.ej2Instances.grid.getColumns()[2].visible = false;
          this.$refs.treegrid.ej2Instances.grid.getColumns()[3].visible = true;
          this.$refs.treegrid.excelExport();
        }
      }
      excelExportComplete() {
        this.$refs.treegrid.ej2Instances.grid.getColumns()[2].visible = true;
        this.$refs.treegrid.ej2Instances.grid.getColumns()[3].visible = false;
      }
  },
  provide: {
      treegrid: [ Page, Toolbar, ExcelExport ]
  }
}
</script>

File name for exported document

You can assign the file name for the exported document by defining fileName property in ExcelExportProperties.

app.vue

<template>
<div id="app">
        <ejs-treegrid ref='treegrid' :dataSource='data' height='220' childMapping='subtasks' :treeColumnIndex='1' :allowPaging='true' :pageSettings='pageSettings' :allowExcelExport='true' :toolbar='toolbarOptions' :toolbarClick='toolbarClick'>
            <e-columns>
                <e-column field='taskID' headerText='Task ID' width='90' textAlign='Right'></e-column>
                <e-column field='taskName' headerText='Task Name' width='160'></e-column>
                <e-column field='startDate' headerText='Start Date' width='90' format="yMd" textAlign='Right'></e-column>
                <e-column field='duration' headerText='Duration' width='80' textAlign='Right'></e-column>
            </e-columns>
        </ejs-treegrid>
</div>
</template>
<script>
import Vue from "vue";
import { TreeGridPlugin, Page, Toolbar, ExcelExport } from "@syncfusion/ej2-vue-treegrid";
import { sampleData } from "./datasource.js";

Vue.use(TreeGridPlugin);

export default {
  data ()  {
    return {
      data: sampleData,
      toolbarOptions: ['ExcelExport'],
      pageSettings: { pageSize: 7 }
    };
  },
  methods: {
      toolbarClick(args) {
        if (args['item'].text === 'Excel Export') {
          let excelExportProperties = {
            fileName:"new.xlsx"
          }
          this.$refs.treegrid.excelExport(excelExportProperties);
        }
    }
  },
  provide: {
      treegrid: [ Page, Toolbar, ExcelExport ]
  }
}
</script>

Persist collapsed state

You can persist the collapsed state in the exported document by defining isCollapsedStatePersist property as true in TreeGridExcelExportProperties parameter of excelExport method.

app.vue

<template>
<div id="app">
        <ejs-treegrid ref='treegrid' :dataSource='data' height='220' childMapping='subtasks' :treeColumnIndex='1' :allowPaging='true' :pageSettings='pageSettings' :allowExcelExport='true' :toolbar='toolbarOptions' :toolbarClick='toolbarClick'>
            <e-columns>
                <e-column field='taskID' headerText='Task ID' width='90' textAlign='Right'></e-column>
                <e-column field='taskName' headerText='Task Name' width='160'></e-column>
                <e-column field='startDate' headerText='Start Date' width='90' format="yMd" textAlign='Right'></e-column>
                <e-column field='duration' headerText='Duration' width='80' textAlign='Right'></e-column>
            </e-columns>
        </ejs-treegrid>
</div>
</template>
<script>
import Vue from "vue";
import { TreeGridPlugin, Page, Toolbar, ExcelExport } from "@syncfusion/ej2-vue-treegrid";
import { sampleData } from "./datasource.js";

Vue.use(TreeGridPlugin);

export default {
  data ()  {
    return {
      data: sampleData,
      toolbarOptions: ['ExcelExport'],
      pageSettings: { pageSize: 7 }
    };
  },
  methods: {
      toolbarClick(args) {
        if (args['item'].text === 'Excel Export') {
          let excelExportProperties = {
              isCollapsedStatePersist: true
          }
          this.$refs.treegrid.excelExport(excelExportProperties);
        }
    }
  },
  provide: {
      treegrid: [ Page, Toolbar, ExcelExport ]
  }
}
</script>
