My Add-In sometimes crashes and takes up huge amounts of memory and is just generally bad performance while I iterate over a range and add hyperlinks.
My hyperlinks almost always follow the formula of URL + CellValue and I wonder if I can add this somehow to an entire range without looping to increase performance?
Here is an example of what I do, note, Excel doesn't seem to "respect" the screen updating, or maybe its just slow after sync, but I can watch it change cells row by row visually its so slow..
const Hyperlink_Settings_Obj = {
address: null,
documentReference: null,
screenTip: null,
textToDisplay: null,
}
context.workbook.application.suspendScreenUpdatingUntilNextSync();
var key_index = 0
for (var ri = 0; ri < Used_Rng_And_Props.rowCount; ++ri) {
var val = Used_Rng_And_Props.values[ri][key_index]
var cell = Used_Rng_And_Props.getCell(ri, key_index)
var hlink_obj = JSON.parse(JSON.stringify(Hyperlink_Settings_Obj))
hlink_obj.address = URL + val
hlink_obj.textToDisplay = val
cell.hyperlink = hlink_obj
}
I have a custom function that hides/shows columns in my tabulator. The column I click on is supposed to hide and several other columns are shown. I have this function working correctly from onclick on an object in a custom cell formatter, but I would like to call it from clicking on the column header. It works except that I can't seem to get a handle of the column I clicked on from column header in order to hide the column.
I'm trying to get the column object and pass it to my function so I can hide that column while I show the others. I'm open to other ways to do this.
this works (cell formatter)
var showForecastCell = function(cell, formatterParams, onRendered){
...
span.onclick = function(){showForecast(cell.getColumn())};
return span
}
this doesn't work (column titleFormatter)
var showForecastHeader = function(t,e,o,i,n){
...
span.onclick = function(){showForecast(t.getColumn())};
return span
}
Is there any way to pass the column object from clicking on the column header? otherwise, if there is a simpler way to hide the column after clicking on the header, I am open to suggestions. I must admit that javascript isn't my strongest language and if I am overlooking something basic, please let me know.
You can check this JsFiddle it hides all other columns except the one you click
for Column call backs you can check documentation here and here
const hideAllButThis = function(e, column) {
const showField = column._column.field;
const columns = column._column.table.columnManager.columns;
for (let i = 0; i < columns.length; i++) {
if (columns[i].field !== showField) {
table.hideColumn("" + columns[i].field + "")
}
}
};
I'd like to be able to delete an entire row in a Google Spreadsheets if the value entered for say column "C" in that row is 0 or blank. Is there a simple script I could write to accomplish this?
Thanks!
I can suggest a simple solution without using a script !!
Lets say you want to delete rows with empty text in column C.
Sort the data (Data Menu -> Sort sheet by column C, A->Z) in the sheet w.r.t column C, so all your empty text rows will be available together.
Just select those rows all together and right-click -> delete rows.
Then you can re-sort your data according to the column you need.
Done.
function onEdit(e) {
//Logger.log(JSON.stringify(e));
//{"source":{},"range":{"rowStart":1,"rowEnd":1,"columnEnd":1,"columnStart":1},"value":"1","user":{"email":"","nickname":""},"authMode":{}}
try {
var ss = e.source; // Just pull the spreadsheet object from the one already being passed to onEdit
var s = ss.getActiveSheet();
// Conditions are by sheet and a single cell in a certain column
if (s.getName() == 'Sheet1' && // change to your own
e.range.columnStart == 3 && e.range.columnEnd == 3 && // only look at edits happening in col C which is 3
e.range.rowStart == e.range.rowEnd ) { // only look at single row edits which will equal a single cell
checkCellValue(e);
}
} catch (error) { Logger.log(error); }
};
function checkCellValue(e) {
if ( !e.value || e.value == 0) { // Delete if value is zero or empty
e.source.getActiveSheet().deleteRow(e.range.rowStart);
}
}
This only looks at the value from a single cell edit now and not the values in the whole sheet.
I wrote this script to do the same thing for one of my Google spreadsheets. I wanted to be able to run the script after all the data was in the spreadsheet so I have the script adding a menu option to run the script.
/**
* Deletes rows in the active spreadsheet that contain 0 or
* a blank valuein column "C".
* For more information on using the Spreadsheet API, see
* https://developers.google.com/apps-script/service_spreadsheet
*/
function readRows() {
var sheet = SpreadsheetApp.getActiveSheet();
var rows = sheet.getDataRange();
var numRows = rows.getNumRows();
var values = rows.getValues();
var rowsDeleted = 0;
for (var i = 0; i <= numRows - 1; i++) {
var row = values[i];
if (row[2] == 0 || row[2] == '') {
sheet.deleteRow((parseInt(i)+1) - rowsDeleted);
rowsDeleted++;
}
}
};
/**

* for invoking the readRows() function specified above.
* The onOpen() function, when defined, is automatically invoked whenever the
* spreadsheet is opened.
* For more information on using the Spreadsheet API, see
* https://developers.google.com/apps-script/service_spreadsheet
*/
function onOpen() {
var sheet = SpreadsheetApp.getActiveSpreadsheet();
var entries = [{
name : "Remove rows where column C is 0 or blank",
functionName : "readRows"
}];
sheet.addMenu("Script Center Menu", entries);
};
Test spreadsheet before:
Running script from menu:
After running script:
I was having a few problems with scripts so my workaround was to use the "Filter" tool.
Select all spreadsheet data
Click filter tool icon (looks like wine glass)
Click the newly available filter icon in the first cell of the column you wish to search.
Select "Filter By Condition" > Set the conditions (I was using "Text Contains" > "word")
This will leave the rows that contain the word your searching for and they can be deleted by bulk selecting them while holding the shift key > right click > delete rows.
This is what I managed to make work. You can see that I looped backwards through the sheet so that as a row was deleted the next row wouldn't be skipped. I hope this helps somebody.
function UpdateLog() {
var returnSheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('RetLog');
var rowCount = returnSheet.getLastRow();
for (i = rowCount; i > 0; i--) {
var rrCell = 'G' + i;
var cell = returnSheet.getRange(rrCell).getValue();
if (cell > 0 ){
logSheet.
returnSheet.deleteRow(i);
}
}
}
quite simple request. Try this :
function try_It(){
deleteRow(2); //// choose col = 2 for column C
}
function deleteRow(col){ // col is the index of the column to check for 0 or empty
var sh = SpreadsheetApp.getActiveSheet();
var data = sh.getDataRange().getValues();
var targetData = new Array();
for(n=0;n<data.length;++n){
if(data[n][col]!='' && data[n][col]!=0){ targetData.push(data[n])};
}
Logger.log(targetData);
sh.getDataRange().clear();
sh.getRange(1,1,targetData.length,targetData[0].length).setValues(targetData);
}
EDIT : re-reading the question I'm not sure if the question is asking for a 'live' on Edit function or a function (like this above) to apply after data has been entered... It's not very clear to me... so feel free to be more accurate if necessary ;)
There is a simpler way:
Use filtering to only show the rows which you want to delete. For example, my column based on which I want to delete rows had categories on them, A, B, C. Through the filtering interface I selected only A and B, which I wanted to delete.
Select all rows and delete them. Doing this, in my example, effectively selected all A and B rows and deleted them; now my spreadsheet does not show any rows.
Turn off the filter. This unhides my C rows. Done!
There is a short way to solve that instead of a script.
Select entire data > Go to menu > click Data tab > select create filter > click on filter next to column header > pop-up will appear then check values you want to delete > click okay and copy the filtered data to a different sheet > FINISH
reading your question carefully, I came up with this solution:
function onOpen() {
// get active spreadsheet
var ss = SpreadsheetApp.getActiveSpreadsheet();
// create menu
var menu = [{name: "Evaluate Column C", functionName: "deleteRow"}];
// add to menu
ss.addMenu("Check", menu);
}
function deleteRow() {
// get active spreadsheet
var ss = SpreadsheetApp.getActiveSpreadsheet();
// get active/selected row
var activeRow = ss.getActiveRange().getRowIndex();
// get content column C
var columnC = ss.getRange("C"+activeRow).getValue();
// evaluate whether content is blank or 0 (null)
if (columnC == '' || columnC == 0) {
ss.deleteRow(parseInt(activeRow));
}
}
This script will create a menu upon file load and will enable you to delete a row, based on those criteria set in column C, or not.
This simple code did the job for me!
function myFunction() {
var ss = SpreadsheetApp.getActiveSpreadsheet(); // get active spreadsheet
var activeRow = ss.getActiveRange().getRowIndex(); // get active/selected row
var start=1;
var end=650;
var match='';
var match2=0; //Edit this according to your choice.
for (var i = start; i <= end; i++) {
var columnC = ss.getRange("C"+i).getValue();
if (columnC ==match || columnC ==match2){ ss.deleteRow(i); }
}
}
The below code was able to delete rows containing a date more than 50 days before today in a particular column G , move these row values to back up sheet and delete the rows from source sheet.
The code is better as it deletes the rows at one go rather than deleting one by one. Runs much faster.
It does not copy back values like some solutions suggested (by pushing into an array and copying back to sheet). If I follow that logic, I am losing formulas contained in these cells.
I run the function everyday in the night (scheduled) when no one is using the sheet.
function delete_old(){
//delete > 50 day old records and copy to backup
//run daily from owner login
var ss = SpreadsheetApp.getActiveSpreadsheet();
var bill = ss.getSheetByName("Allotted");
var backss = SpreadsheetApp.openById("..."); //backup spreadsheet
var bill2 = backss.getSheetByName("Allotted");
var today=new Date();
//process allotted sheet (bills)
bill.getRange(1, 1, bill.getMaxRows(), bill.getMaxColumns()).activate();
ss.getActiveRange().offset(1, 0, ss.getActiveRange().getNumRows() - 1).sort({column: 7, ascending: true});
var data = bill.getDataRange().getValues();
var delData = new Array();
for(n=data.length-1; n>1; n--){
if(data[n][6] !=="" && data[n][6] < today.getTime()-(50*24*3600*1000) ){ //change the condition as per your situation
delData.push(data[n]);
}//if
}//for
//get first and last row no to be deleted
for(n=1;n<data.length; n++){
if(data[n][6] !=="" && data[n][6] < today.getTime()-(50*24*3600*1000) ){
var strow=n+1 ; //first row
break
}//if
}//for
for(n=data.length-1; n>1; n--){
if(data[n][6] !=="" && data[n][6] < today.getTime()-(50*24*3600*1000) ){
var ltrow=n+1 ; //last row
break
}//if
}//for
var bill2lr=bill2.getLastRow();
bill2.getRange((bill2lr+1),1,delData.length,delData[0].length).setValues(delData);
bill.deleteRows(strow, 1+ltrow-strow);
bill.getRange(1, 1, bill.getMaxRows(), bill.getMaxColumns()).activate();
ss.getActiveRange().offset(1, 0, ss.getActiveRange().getNumRows() - 1).sort({column: 6, ascending: true}); //get back ordinal sorting order as per column F
}//function
i am having difficulties with open xml sdk:
i am trying to generate excel file with several columns that have numbers and i want to have total sum at the end
i have tried to Generate Table Definition Part Content and inside define every column (id, name etC). If column has true for TotalColumn, it adds code (rough example)
var column = new TableColumn{
id = 1,
name = "example",
TotalsRowFunction = TotalsRowFunctionValues.Sum,
TotalsRowFormula = new TotalsRowFormula("=SUBTOTAL(109;[" + rowName + "])")
};
I can't get it to work, when i open excel it reports error, but it doesn't explicitly says what the problem is... I tried with microsoft validator but can't figure anything out...
I'd appreciate any help / example code since i can't google anything out
EDIT:
i use this at the end:
workbookPart.Workbook.CalculationProperties.ForceFullCalculation = true;
workbookPart.Workbook.CalculationProperties.FullCalculationOnLoad = true;
Why not use a cell formula?
E.g.
cell.DataType = new EnumValue<CellValues>(CellValues.Number);
cell.CellFormula = new CellFormula(string.Format("=SUBTOTAL({0};[{1}])", "109", rowName));
//This will force a full recalculation of all the cells
workbookPart.Workbook.CalculationProperties.ForceFullCalculation = true;
workbookPart.Workbook.CalculationProperties.FullCalculationOnLoad = true;
I ended using EPPlus for this as it seems to be working simple and efficient
All,
I've been looking all day and have tried numerous solutions, but just can't get it to work. Our team projects a list that is constantly updated and we want to highlight only newly created items for 5 minutes. After 5 minutes, the row would return to normal. (FYI- the list is projected on a display and updated using AJAX asynchronous update every 15 seconds)
Basically, I want to set conditional formatting on list items created in the last 5 minutes. If the item was created in the last 5 minutes, the row will be highlighted. After the 5 minutes are up, the row would return to normal.
I tried SharePoint Designer conditional formatting by creating a calculated column in Date/Time format called "Created + 5" and tried to set an expression where the formatting is applied (row is highlighted) when "Created + 5" is greater than or equal to current date. So after 5 minutes, the row will no longer be highlighted (because the current date/time will exceed the "Created + 5" value)
Here is the expression from the SPD Advanced Condition Builder:
ddwrt:DateTimeTick(ddwrt:GenDisplayName(string($thisNode/#Created_x0020__x002b__x0020_5_x))) >=
ddwrt:DateTimeTick(ddwrt:GenDisplayName(string($Today)))
I think the problem is that the [Current Date] option ($Today in the expression builder) only accounts for date and not time. It looks like it just ends up highlighting everything that was created today, which is not very useful.
Any thoughts or help!? I have never messed with the advanced conditions because usually the basic stuff works fine for me! If anyone has any other ideas too like JavaScript or anything else that would work, I am open to that too as long as it will continuously update!
Thanks all!!!!
[Today] actually doesn't work properly in 2010, there are some workarounds though, e.g. https://abstractspaces.wordpress.com/2008/05/19/use-today-and-me-in-calculated-column/.
You can also use the approach with calculated column: https://blog.splibrarian.com/2012/06/06/using-calculated-columns-to-add-color-coding-to-your-sharepoint-lists/
Since you want this to update automatically without requiring someone to manually refresh the page, JavaScript is your best bet. You can have a function run repeatedly on a specified interval, checking the current date against the values in a date column.
Something like the following code would work, though you may need to tweak the CSS selectors specified in the calls to document.querySelector and querySelectorAll to match your particular HTML.
<script>
formatCell();
function formatCell(){
var frequencyToCheck = 2 /* num seconds between updates */
var minutes = 5; /* num minutes back to highlight */
var targetColumn = "Display name of the column you want to check";
var formatting = "background-color:darkred;color:red;font-weight:bold;";
var comparisonDate = new Date();
comparisonDate.setHours(comparisonDate.getHours() - minutes);
var tables = document.querySelectorAll("table.ms-listviewtable"); /* should get all list view web parts on the page */
var t_i = 0;
while(t_i < tables.length){
var headings = tables[t_i].rows[0].cells;
var columnIndex = null;
var h_i = 0;
while(h_i < headings.length){
var heading = headings[h_i].querySelector("div:first-child");
if(heading != null){
var displayName = heading.DisplayName ? heading.DisplayName : (heading.innerText ? heading.innerText : heading.textContent);
displayName = displayName.replace(/^\s+|\s+$/g,''); /* removes leading and trailing whitespace */
if(displayName === targetColumn){
columnIndex = h_i;
break;
}
}
h_i += 1;
}
if(columnIndex != null){ /* we found a matching heading */
var rows = tables[t_i].rows;
for(var i = (rows.length > 0 ? 1 : 0); i < rows.length; i++){
var cells = rows[i].children;
if(cells.length <= columnIndex){continue;}
var valueToEval = cells[columnIndex].innerText ? cells[columnIndex].innerText : cells[columnIndex].textContent;
if(typeof valueToEval == "undefined"){valueToEval = "";}
valueToEval = new Date(valueToEval);
if(valueToEval > comparisonDate){
cells[columnIndex].setAttribute("style",formatting);
}else{
cells[columnIndex].setAttribute("style","");
}
}
}
t_i +=1;
}
setTimeout(formatCell,frequencyToCheck * 1000);
}
</script>
One potential pitfall is that while this approach will "age" records appropriately based on their displayed values (causing them to stop being highlighted as they grow stale), it won't automatically pick up new changes to the list; you'd need to refresh the page (or at least refresh the view in the web part) whenever you want to see updated information.
