I am trying to read some values from excel file. For that I need to know the last row of every column. For this I am using find function. But, it is giving run time error. I am using c++. Here is the code
Excel::_ApplicationPtr app;
::CoInitialize(NULL);
app.CreateInstance("Excel.Application");
Excel::_WorkbookPtr wbk = app->Workbooks->Open("Algo_Sample.xlsx"));
Excel::_WorksheetPtr sheet = wbk->Sheets->Item[1];
Excel::RangePtr range_Ptr = sheet->GetRange("A:A");
range_Ptr->Find("Subject","A1",Excel::xlValues,Excel::xlWhole,Excel::xlByRows,Excel::xlNext,false,false);
I checked with the debugger, the error is in last line. This is the snap shot of the excel file
I will be very thankful to the person who sheds light on this issue
Note: I am using windows XP, Visual Studio 2008,office 2007,c++.
I am not sure about the link with C++, but within Excel, if you want to assign the last used row of a specific column, I use this:
MyLastRowCount = Cells(Rows.Count, "A").End(xlUp).Row
Here the variable MyLastRowCount is assigned the row number of the last used cell in column A.
What it does is, jump to the last available cell (A65536 for xl03, or A1048576 for xl07/10) in column A and then jump up to the first occupied cell from below.

Robert Ilbrink

Goal: I have a bunch of keywords I'd like to categorise automatically based on topic parameters I set. Categories that match must be in the same column so the keyword data can be filtered.
e.g. If I have "Puppies" as a first topic, it shouldn't appear as a secondary or third topic otherwise the data cannot be filtered as needed.
Example Data: https://docs.google.com/spreadsheets/d/1TWYepApOtWDlwoTP8zkaflD7AoxD_LZ4PxssSpFlrWQ/edit?usp=sharing
Video: https://drive.google.com/file/d/11T5hhyestKRY4GpuwC7RF6tx-xQudNok/view?usp=sharing
Parameters Tab: I will add words in columns D-F that change based on the keyword data set and there will often be hundreds, if not thousands, of options for larger data sets.
Categories Tab: I'd like to have a formula or script that goes down the columns D-F in Parameters and fills in a corresponding value (in Categories! columns D-F respectively) based on partial match with column B or C (makes no difference to me if there's a delimiter like a space or not. Final data sheet should only have one of these columns though).
Things I've Tried:
I've tried a bunch of things. Nested IF formula with regexmatch works but seems clunky.
e.g. this formula in Categories! column D
=IF(REGEXMATCH($B2,LOWER(Parameters!$D$3)),Parameters!$D$3,IF(REGEXMATCH($B2,LOWER(Parameters!$D$4)),Parameters!$D$4,""))
I nested more statements changing out to the next cell in Parameters!D column (as in , manually adding $D$5, $D$6 etc) but this seems inefficient for a list thousands of words long. e.g. third topic will get very long once all dog breed types are added.
Any tips?
Functionality I haven't worked out:
if a string in Categories B or C contains more than one topic in the parameters I set out, is there a way I can have the first 2 to show instead of just the first one?
e.g. Cell A14 in Categories, how can I get a formula/automation to add both "Akita" & "German Shepherd" into the third topic? Concatenation with a CHAR(10) to add to new line is ideal format here. There will be other keywords that won't have both in there in which case these values will just show up individually.
Since this data set has a bunch of mixed breeds and all breeds are added as a third topic, it would be great to differentiate interest in mixes vs pure breeds without confusion.
Any ideas will be greatly appreciated! Also, I'm open to variations in layout and functionality of the spreadsheet in case you have a more creative solution. I just care about efficiently automating a tedious task!!
Try using custom function:
To create custom function:
1.Create or open a spreadsheet in Google Sheets.
2.Select the menu item Tools > Script editor.
3.Delete any code in the script editor and copy and paste the code below into the script editor.
4.At the top, click Save save.
To use custom function:
1.Click the cell where you want to use the function.
2.Type an equals sign (=) followed by the function name and any input value — for example, =DOUBLE(A1) — and press Enter.
3.The cell will momentarily display Loading..., then return the result.
Code:
function matchTopic(p, str) {
var params = p.flat(); //Convert 2d array into 1d
var buildRegex = params.map(i => '(' + i + ')').join('|'); //convert array into series of capturing groups. Example (Dog)|(Puppies)
var regex = new RegExp(buildRegex,"gi");
var results = str.match(regex);
if(results){
// The for loops below will convert the first character of each word to Uppercase
for(var i = 0 ; i < results.length ; i++){
var words = results[i].split(" ");
for (let j = 0; j < words.length; j++) {
words[j] = words[j][0].toUpperCase() + words[j].substr(1);
}
results[i] = words.join(" ");
}
return results.join(","); //return with comma separator
}else{
return ""; //return blank if result is null
}
}
Example Usage:
Parameters:
First Topic:
Second Topic:
Third Topic:

I've added a new sheet ("Erik Help") with separate formulas (highlighted in green currently) for each of your keyword columns. They are each essentially the same except for specific column references, so I'll include only the "First Topic" formula here:
=ArrayFormula({"First Topic";IF(A2:A="",,IFERROR(REGEXEXTRACT(LOWER(B2:B&C2:C),JOIN("|",LOWER(FILTER(Parameters!D3:D,Parameters!D3:D<>""))))) & IFERROR(CHAR(10)®EXEXTRACT(REGEXREPLACE(LOWER(B2:B&C2:C),IFERROR(REGEXEXTRACT(LOWER(B2:B&C2:C),JOIN("|",LOWER(FILTER(Parameters!D3:D,Parameters!D3:D<>""))))),""),JOIN("|",LOWER(FILTER(Parameters!D3:D,Parameters!D3:D<>""))))))})
This formula first creates the header (which can be changed within the formula itself as you like).
The opening IF condition leaves any row in the results column blank if the corresponding cell in Column A of that row is also blank.
JOIN is used to form a concatenated string of all keywords separated by the pipe symbol, which REGEXEXTRACT interprets as OR.
IFERROR(REGEXEXTRACT(LOWER(B2:B&C2:C),JOIN("|",LOWER(FILTER(Parameters!D3:D,Parameters!D3:D<>""))))) will attempt to extract any of the keywords from each concatenated string in Columns B and C. If none is found, IFERROR will return null.
Then a second-round attempt is made:
& IFERROR(CHAR(10)®EXEXTRACT(REGEXREPLACE(LOWER(B2:B&C2:C),IFERROR(REGEXEXTRACT(LOWER(B2:B&C2:C),JOIN("|",LOWER(FILTER(Parameters!D3:D,Parameters!D3:D<>""))))),""),JOIN("|",LOWER(FILTER(Parameters!D3:D,Parameters!D3:D<>"")))))
Only this time, REGEXREPLACE is used to replace the results of the first round with null, thus eliminating them from being found in round two. This will cause any second listing from the JOIN clause to be found, if one exists. Otherwise, IFERROR again returns null for round two.
CHAR(10) is the new-line character.
I've written each of the three formulas to return up to two results for each keyword column. If that is not your intention for "First Topic" and "Second Topic" (i.e., if you only wanted a maximum of one result for each of those columns), just select and delete the entire round-two portion of the formula shown above from the formula in each of those columns.
I have a column in my table which looks like below.
ResourceIdentifier
------------------
arn:aws:ec2:us-east-1:7XXXXXX1:instance/i-09TYTYTY79716
arn:aws:glue:us-east-1:5XXXXXX85:devEndpoint/etl-endpoint
i-075656565f7fea3
i-02c3434343f22
qa-271111145-us-east-1-raw
prod-95756565631-us-east-1-raw
prod-957454551631-us-east-1-isin-repository
i-02XXXXXXf0
I want a new column called 'Trimmed Resource Identifier' which looks at ResourceIdentifier and if the value starts with "arn", then returns value after last "/", else returns the whole string.
For eg.
arn:aws:ec2:us-east-1:7XXXXXX1:instance/i-09TYTYTY79716 ---> i-09TYTYTY797168
i-02XXXXXXf0 --> i-02XXXXXXf0
How do I do this ? I tried creating a new column called "first 3 letters" by extracting first 3 letters of the ResourceIdentifier column but I am getting stuck at the step of adding conditional column. Please see the image below.
Is there a way I can do all of this in one step using DAX instead of creating a new intermediate column ?
Many Thanks
The GUI is too simple to do exactly what you want but go ahead and use it to create the next step, which we can then modify to work properly.
Filling out the GUI like this
will produce a line of code that looks like this (turn on the Formula Bar under the View tab in the query editor if you don't see this formula).
= Table.AddColumn(#"Name of Previous Step Here", "Custom",
each if Text.StartsWith([ResourceIdentifier], "arn") then "output" else [ResourceIdentifier])
The first three letters bit is already handled with the operator I chose, so all that remains is to change the "output" placeholder to what we actually want. There's a handy Text.AfterDelimiter function we can use for this.
Text.AfterDelimiter([ResourceIdentifier], "/", {0, RelativePosition.FromEnd})
This tells it to take the text after the first / (starting from the end). Replace "output" with this expression and you should be good to go.
I have a data set of around 3000 columns, but some of the columns have several cells that contain cells "na". These rows have no importance since they don't have data that I will need, is there a command in google sheets that can either highlight the entire row that contains that text or delete the entire row containing that text?
Any help would be appreciated.
https://docs.google.com/spreadsheets/d/1u8OUfQOzgAulf1a8bzQ8SB5sb5Uvb1I4amF5sdGEBlc/edit?usp=sharing
My document ^.
you can use this formula to color all na rows:
=ARRAYFORMULA(REGEXMATCH(TRANSPOSE(QUERY(TRANSPOSE($A1:$Z),,999^99)), " na "))
This answer based on what I understand, sorry if I'm wrong. You can use conditional formatting to highlight all NA text
This is what rules I used
Here are another answers that may help you
Delete a row in Google Spreadsheets if value of cell in said row is 0 or blank
Google Sheets: delete rows containing specified data
Deleting Cells in Google Sheets without removing a whole row
Sorry for bad English.
I'm not sure if my understing is well but see below what you can do.
This is a google script function which color the whole column where "na" is in
function myFunction() {
//get the spreadsheet where the function is running
var ss = SpreadsheetApp.getActive()
//Replace "the name of your sheet" by your sheet name" be careful its case sensitive.
var sheet = ss.getSheetByName("The name of your sheet")
//Get all your data as an array (If your sheet has no header, change 2 by 1 and (sheet.getLastRow()-1) by sheet.getLastRow())
var values = sheet.getRange(2,1,(sheet.getLastRow()-1), sheet.getLastColumn()).getValues();
//For each column
for (var i = 0; i< sheet.getLastColumn(); i++){
//using function map is helping to select one column by one column
var mapValues = values.map(function(r){return r[i]});
//Searching your keyword in the column, in your case it's "na"
var position = mapValues.indexOf("Put the string that you are looking for, in your case 'na'");
//if at least there is one "na" inside the column
if( position >-1){
//then this color have to get red color as a background
var wholeColumn = sheet.getRange(2,(i+1),(sheet.getLastRow()-1));
wholeColumn.setBackground("red");
}
}
}``
Let me know if it works
I have issues with cell protection.
I would like to protect just one column, B for example.
So I tried:
$sheet->getProtection()->setSheet(true);
$highestRow = $sheet->getHighestRow();
$sheet->getStyle('A1:J2000)->getProtection()->setLocked( PHPExcel_Style_Protection::PROTECTION_UNPROTECTED );
for($i=1;$i<=$highestRow;$i++)
{
$sheet->getStyleByColumnAndRow(1,$i)->getProtection()->setLocked(PHPExcel_Style_Protection::PROTECTION_PROTECTED);
}
But it's really slow, and not good because if I need to open my sheet again
$highestRow = $sheet->getHighestRow(); will return "J".
Another solution would be to get the last non-empty column, do you know how to do that? Because getHighestRow(Column) return the columns unprotected or empty.
The loop is slow because you're applying the style to each individual cell, rather than to the range of cells demonstrated in your
$sheet->getStyle('A1:J2000)->getProtection()->setLocked( PHPExcel_Style_Protection::PROTECTION_UNPROTECTED );
line
: one call to set the style for a range of 1000 cells is more that 1000 times faster than applying it to each of 1000 cells individually.
$sheet->getHighestDataRow();
will return the highest row in the worksheet that contains actual data values
$sheet->getHighestDataColumn();
is the column equivalent
First you can protect complete sheet. After that you can uprotect others. This code will protect the first column and first
$objPHPExcel->getActiveSheet()->getProtection()->setSheet(true);
$objPHPExcel->getActiveSheet()->getStyle('B2:Z400')->getProtection()->setLocked(PHPExcel_Style_Protection::PROTECTION_UNPROTECTED);
I have a bunch of cells whose font size I'd like to tweak if their content is overflowing, until it all fits. I'd like to write a macro to do this, unless there's a conditional formatting or other formulaic way of doing it. Is there a property that tells whether a cell is overflowing? If so, what is it?
'open office 3
'get current document
oDoc = ThisComponent
' get first work sheet
oSheet = oDoc.getSheets().getByIndex(0)
'first cell in the work sheet
Cell = oSheet.getCellByPosition(0, 0)
MsgBox Cell.CharHeight
Happy Coading :))
