When I try to export to excel the following message appears: Cannot read property 'styles' of null. I'm following the documentation ui-grid-docs.
enter image description here
I am using ui-grid v4.4.11. This is a bit of a hack, but I found that docDefinition was being set to null at line 20343. I commented it out and it now works. See code same of prepareAsExcel function where I commented out docDefinition.
prepareAsExcel: function(grid, workbook, sheet) {
var docDefinition = {
styles: {
}
};
if ( grid.options.exporterExcelCustomFormatters ){
//docDefinition = grid.options.exporterExcelCustomFormatters( grid, workbook, docDefinition );
}
if ( grid.options.exporterExcelHeader ) {
if (angular.isFunction( grid.options.exporterExcelHeader )) {
grid.options.exporterExcelHeader(grid, workbook, sheet, docDefinition);
} else {
var headerText = grid.options.exporterExcelHeader.text;
var style = grid.options.exporterExcelHeader.style;
sheet.data.push([{value: headerText, metadata: {style: docDefinition.styles[style].id}}]);
}
}
return docDefinition;
},

I have a custom excel output class that I'm using to parse the grid, and in some cases replace the data in the grid with template data. In this particular instance, the data i want to output is multi-line. I have it working to that point but the exported sheet is one line high so you can't see lines two thru-seven in the field.
desired result:
actual result:
Here's a relevant section of my code. It's the parsing loop that applies the templates and strips html, but adds line breaks first.
if (me.ColumnTemplates && $.isArray(me.ColumnTemplates)) {
for (let c = 0; c < me.ColumnTemplates.length; c++) {
let ct = me.ColumnTemplates[c];
if (ct.template(dr).includes("</br>")) {
sheet.rows[r + 1].cells[ct.cellIndex - 1].wrap = true;
}
me.elem.innerHTML = ct.template(dr).replace(/<\/br>/g, "\n");
sheet.rows[r + 1].cells[ct.cellIndex - 1].value = me.elem.textContent || me.elem.innerText || "";
}
}
any help would be appreciated. I would like to either have a setting that makes this "just work" or have a way to compute the needed height and set it manually. Either is fine.
I'm not aware of a way to auto-size it, but you can set row height it via sheets.rows.height:
<script>
var workbook = new kendo.ooxml.Workbook({
sheets: [{
rows: [{
cells: [{ value: "this row is 100px high" }],
height: 100
}, {
cells: [{ value: "this row is 200px high" }],
height: 200
}]
}]
});
</script>
example found here
Updating your code to utilize each in the template html you can do something like the following:
if (me.ColumnTemplates && $.isArray(me.ColumnTemplates)) {
for (let c = 0; c < me.ColumnTemplates.length; c++) {
let ct = me.ColumnTemplates[c];
if (ct.template(dr).includes("</br>")) {
sheet.rows[r + 1].cells[ct.cellIndex - 1].wrap = true;
sheet.rows[r + 1].height = (ct.template(dr).match(/<\/br>/g) || []).length * 20 + 20; //20 was default row height.
}
me.elem.innerHTML = ct.template(dr).replace(/<\/br>/g, "\n");
sheet.rows[r + 1].cells[ct.cellIndex - 1].value = me.elem.textContent || me.elem.innerText || "";
}
}
Set column width to auto
Solution 1
When kendo grid bound to data source in JavaScript/jQuery
excelExport: function(e) {
var columns = e.workbook.sheets[0].columns;
columns.forEach(function(column){
// also delete the width if it is set
delete column.width;
column.autoWidth = true;
});
}
more details
Solution 2
When kendo grid is taking data source from action controller not bound to data source in jQuery then add event to call a JavaScript function on excel export
function exportToExcelSheetColumnWidthChange(e) {
var columns = e.workbook.sheets[0].columns;
columns.forEach(function (column) {
delete column.width;
column.autoWidth = true;
});
};
Add event to the kendo grid control
.Events(e => e.ExcelExport("exportToExcelSheetColumnWidthChange"))
There is a problem with my work. since Firebase's Web/JavaScript API always returns the full tree under the nodes that we request.
So in my case i retrieved all of existing fields from firebase including sensitive fields first and after that I want to export to excel selected fields only, not all of the fields that i got. the problem is, I always succeed exported all existing fields, including the sensitive fields.
Can I export selected field only and exclude the sensitive field? Below is my code:
I retrieve all of my fields include the data from firebase in my .ts file like this:
getData() {
this.dataLoading = true;
this.querySubscription = this._backendService.getDocs('report')
.subscribe(members => {
this.members = members;
this.dataSource = new MatTableDataSource(members);
this.dataSource.paginator = this.paginator;
this.dataSource.sort = this.sort;
},
(error) => {
this.error = true;
this.errorMessage = error.message;
this.dataLoading = false;
},
() => { this.error = false; this.dataLoading = false; });
}
//export func
exportAsXLSX():void{
this._backendService.exportAsExcelFile(this.members, 'sample');
}
My Backend service Code :
getDocs(coll:string,filters?:any){
this.itemsCollection=this.afs.collection<any>(this.getCollectionURL(coll));
return this.itemsCollection.valueChanges();
}
getCollectionURL(filter){
return "ReportApp/fajar/"+filter;
}
//export func
public exportAsExcelFile(json: any[], excelFileName: string): void {
const worksheet: XLSX.WorkSheet = XLSX.utils.json_to_sheet(json);
const workbook: XLSX.WorkBook = { Sheets: { 'data': worksheet }, SheetNames: ['data'] };
const excelBuffer: any = XLSX.write(workbook, { bookType: 'xlsx', type: 'array' });
this.saveAsExcelFile(excelBuffer, excelFileName);
}
private saveAsExcelFile(buffer: any, fileName: string): void {
const data: Blob = new Blob([buffer], {type: EXCEL_TYPE});
FileSaver.saveAs(data, fileName + '_export_' + new Date().getTime() + EXCEL_EXTENSION);
}
as for reference im using code from here to exporting to excel :https://medium.com/#madhavmahesh/exporting-an-excel-file-in-angular-927756ac9857
as u can see I put all of my data into this.member variable and export em, But the result is that I exported all of em, i want to export selected fields only.
You will need to "trim down" the array of member data before you send it to your exportAsExcelFile() method. Your problem is that you are passing ALL of the member data to that export function. So the solution is to remove any sensitive information before you call the export function.
exportAsXLSX():void {
// TRIM DOWN ARRAY HERE
this._backendService.exportAsExcelFile(this.members, 'sample');
}
Since you didn't provide your member database structure, or details of what you consider sensitive information, I'll provide a generic example. You have an array of members... Most likely, you've made each "member" in the array into an object... so we need to loop over that array and delete the "sensitive" property of each member object.
As a precaution, since we don't want to delete the properties from the ACTUAL array, since arrays are reference-types, and since you might need those details elsewhere... let's make a copy of the array - a deep copy to ensure even nested objects are copied.
var newMemberArray = JSON.parse(JSON.stringify(this.members))
Then, we need to loop over that new array and delete our sensitive properties:
newMemberArray.forEach(function(m){
delete m.sensitivePropertyName1;
delete m.sensitivePropertyName2;
});
and pass that "sanitized" array to your export function... so putting all this together, something like:
exportAsXLSX():void {
var newMemberArray = JSON.parse(JSON.stringify(this.members))
newMemberArray.forEach(function(m){ delete m.sensitivePropertyName });
this._backendService.exportAsExcelFile(newMemberArray, 'sample');
}

How can I export nested tree data as a CSV file when using Tabulator? I tried using the table.download("csv","data.csv") function, however, only the top-level data rows are exported.
It looks like a custom file formatter or another option may be necessary to achieve this. It seems silly to re-write the CSV downloader, so while poking around the csv downloader in the download.js module, it looks like maybe adding a recursive function to the row parser upon finding a "_children" field might work.
I am having difficulty figuring out where to get started.
Ultimately, I need to have the parent-to-child relationship represented in the CSV data with a value in a parent ID field in the child rows (this field can be blank in the top-level parent rows because they have no parent). I think I would need to include an ID and ParentID in the data table to achieve this, and perhaps enforce the validation of that key using some additional functions as data is inserted into the table.
Below is currently how I am exporting nested data tables to CSV. This will insert a new column at the end to include a parent row identifier of your choice. It would be easy to take that out or make it conditional if you do not need it.
// Export CSV file to download
$("#export-csv").click(function(){
table.download(dataTreeCSVfileFormatter, "data.csv",{nested:true, nestedParentTitle:"Parent Name", nestedParentField:"name"});
});
// Modified CSV file formatter for nested data trees
// This is a copy of the CSV formatter in modules/download.js
// with additions to recursively loop through children arrays and add a Parent identifier column
// options: nested:true, nestedParentTitle:"Parent Name", nestedParentField:"name"
var dataTreeCSVfileFormatter = function(columns, data, options, setFileContents, config){
//columns - column definition array for table (with columns in current visible order);
//data - currently displayed table data
//options - the options object passed from the download function
//setFileContents - function to call to pass the formatted data to the downloader
var self = this,
titles = [],
fields = [],
delimiter = options && options.delimiter ? options.delimiter : ",",
nestedParentTitle = options && options.nestedParentTitle ? options.nestedParentTitle : "Parent",
nestedParentField = options && options.nestedParentField ? options.nestedParentField : "id",
fileContents,
output;
//build column headers
function parseSimpleTitles() {
columns.forEach(function (column) {
titles.push('"' + String(column.title).split('"').join('""') + '"');
fields.push(column.field);
});
if(options.nested) {
titles.push('"' + String(nestedParentTitle) + '"');
}
}
function parseColumnGroup(column, level) {
if (column.subGroups) {
column.subGroups.forEach(function (subGroup) {
parseColumnGroup(subGroup, level + 1);
});
} else {
titles.push('"' + String(column.title).split('"').join('""') + '"');
fields.push(column.definition.field);
}
}
if (config.columnGroups) {
console.warn("Download Warning - CSV downloader cannot process column groups");
columns.forEach(function (column) {
parseColumnGroup(column, 0);
});
} else {
parseSimpleTitles();
}
//generate header row
fileContents = [titles.join(delimiter)];
function parseRows(data,parentValue="") {
//generate each row of the table
data.forEach(function (row) {
var rowData = [];
fields.forEach(function (field) {
var value = self.getFieldValue(field, row);
switch (typeof value === "undefined" ? "undefined" : _typeof(value)) {
case "object":
value = JSON.stringify(value);
break;
case "undefined":
case "null":
value = "";
break;
default:
value = value;
}
//escape quotation marks
rowData.push('"' + String(value).split('"').join('""') + '"');
});
if(options.nested) {
rowData.push('"' + String(parentValue).split('"').join('""') + '"');
}
fileContents.push(rowData.join(delimiter));
if(options.nested) {
if(row._children) {
parseRows(row._children, self.getFieldValue(nestedParentField, row));
}
}
});
}
function parseGroup(group) {
if (group.subGroups) {
group.subGroups.forEach(function (subGroup) {
parseGroup(subGroup);
});
} else {
parseRows(group.rows);
}
}
if (config.columnCalcs) {
console.warn("Download Warning - CSV downloader cannot process column calculations");
data = data.data;
}
if (config.rowGroups) {
console.warn("Download Warning - CSV downloader cannot process row groups");
data.forEach(function (group) {
parseGroup(group);
});
} else {
parseRows(data);
}
output = fileContents.join("\n");
if (options.bom) {
output = "\uFEFF" + output;
}
setFileContents(output, "text/csv");
};
as of version 4.2 it is currently not possible to include tree data in downloads, this will be comming in a later release
I have just started with Office Addins and I'm experimenting with the functionalities. I have several VBA Userforms that I would want to replace with popups from the Office add-in.
I am using the following code to enter a string into a cell(nothing fancy, I know) but I would want to check if the cell if empty before passing the value. If it is, enter (arg.message).
the problem I have encountered:
with if (range.value == "") the value is being set in "A4" even if "A3" if empty;
with if (range.value == " ") the value is not being entered in any cells.
Can anyone give me an example of how to check if a cell is empty?
I know it seems trivial but I have only found examples of how to check with col and row numbers for conditional formatting. I am trying to test all these functionalities to be able to start moving stuff from VBA to OfficeJS.
Thanks,
Mike

The Range object has a values property, but not a value property. So range.value in your condition test is undefined which does not match an empty string; hence the else clause runs.
A couple of other things:
Your condition tries to read a property of the range object. You have to load the property and call context.sync before you can read the property.
The value of the range.values property is a two-dimensional array (although it may have a single value in it if the range is a single cell). It is not a string, so comparing it with an empty string will always be false.
If I understand your goal, I think you should be testing with whether range.values (after you load it and sync) has an empty string in it's only cell. For example, if (range.values[0][0] === ""). Even better from a performance standpoint is to load the range.valueTypes property (and sync) and then compare like this: if (range.valueTypes[0][0] === Excel.RangeValueType.empty).
I am new to YUI and I want to load YUI 2 in 3 locally, not from CDN. I have pasted both 2 and 3 in same directory named Scripts. I am pasting my code below:
<script type="text/javascript" src="/Scripts/build-yui3/yui/yui-min.js"></script>
function showError(panelId) {
YUI({
groups: {
yui2: {
base: '/build-yui2/',
// If you have a combo service, you can configure that as well
// combine: true,
// comboBase: 'http://myserver.com/combo?',
// root: '/2in3/build/',
patterns: {
'yui2-': {
configFn: function(me) {
if(/-skin|reset|fonts|grids|base/.test(me.name)) {
me.type = 'css';
me.path = me.path.replace(/\.js/, '.css');
me.path = me.path.replace(/\/yui2-skin/, '/assets/skins/sam/yui2-skin');
}
}
}
}
}
}
}).use('dd-drag', 'yui2-container', function (Y) {
Y.one("#" + panelId).setStyle('display', null);
var YAHOO = Y.YUI2;
var config = {
close: true,
width: "300px",
fixedcenter: true,
modal: true
};
panel = new YAHOO.widget.Panel(panelId, config);
var keylistener = new YAHOO.util.KeyListener(
document, {
keys: 27
}, {
fn: panel.hide,
scope: panel,
correctScope: true
});
panel.cfg.queueProperty("keylisteners", keylistener);
panel.render();
});
}
But this is not working. Throwing error: "YAHOO is undefined". Please help. Thanks..
Add an onFailure: function (error) {} method to your YUI3 config object. The error it gives you will tell you which files didn't load properly. I'm guessing the base property needs to be a full path not a relative path. I've never used patterns so I'm not sure how to debug it.
