Unable to delete or load data with Sheets

Remove the web1.GET on both and try

it still exits me out of app. One time I saw a notification say "given URL is not valid"

Do You want to delete the row by web get request? (Scripturl) or by spreadsheet component?

I want to delete the row that has the chosen value (listviewer selection)

for ex: If I chose team A, then whatever row says "team A" would delete.

All the rows to be delete whichever col B has the text Team A?

I imagine that the text present in col B and in such case, in your existing codes pls add this and deploy it once again then through script url method delete it.

function deleteAllRowsByColumnB(dataArray, sheet) {
    var values = sheet.getDataRange().getValues();
    var toDeleteValue = dataArray[0][1]; // Extract Column B value (Index 1)
    var deleted = false;

    for (var i = values.length - 1; i >= 0; i--) {
        if (values[i][1] === toDeleteValue) { // Check if Column B value matches
            sheet.deleteRow(i + 1); // Delete row (1-based index)
            deleted = true;
        }
    }
    
    if (deleted) {
        return ContentService.createTextOutput('All matching rows deleted successfully.');
    } else {
        return ContentService.createTextOutput('No matching row found.');
    }
}

Or share your existing code in which i will make changes and give you

here you can see the data is in column B,
All rows are listed in listviewer too,
if user selected a certain team (for example, row4 Varsity girls soccer)
row4 would be deleted.

ok I will try code.

It seems you will be sending partials data, in such case you should try this code

function deleteAllRowsByPartialColumnB(dataArray, sheet) {
    var values = sheet.getDataRange().getValues();
    var partialText = dataArray[0][1]; // Extract the partial text from Column B (Index 1)
    var deleted = false;

    for (var i = values.length - 1; i >= 0; i--) {
        if (values[i][1] && values[i][1].toString().includes(partialText)) { // Check if Column B contains the partial text
            sheet.deleteRow(i + 1); // Delete row (1-based index)
            deleted = true;
        }
    }
    
    if (deleted) {
        return ContentService.createTextOutput('Matching rows deleted successfully.');
    } else {
        return ContentService.createTextOutput('No matching row found.');
    }
}

what do I do after the code is deployed
How do I use scripturl method to delete?

Is there any way to delete selected data without code?

After listview picking 
Set web2url to script url?+partialText={ListViewSelection}
Call Web2.get

When web2 got text
If get response code =200
Then set notification to "Success"
function doGet(e) {
    var sheet = SpreadsheetApp.openById("YOUR_SHEET_ID").getSheetByName("YOUR_SHEET_NAME");
    var partialText = e.parameter.partialText; // Get partial text from the URL parameter

    if (!partialText) {
        return ContentService.createTextOutput("Error: No search text provided.");
    }

    var dataArray = [[null, partialText]]; // Format data for the delete function
    return deleteAllRowsByPartialColumnB(dataArray, sheet);
}

Your sheet name is not Sheet1.

See the dump procedure for the real name.

You still need the proper credential file to do a component delete row.
(The Get Sheet block can work without it.)

By the way, this is how you prevent blank input:

I replace the AND with an OR.

(Besides lining the two clauses up for readability)

There is also a problem with how you remove a row.

The filter result is a LIST of row numbers.

The remove row block can only accept a single row number, so you have to check if the list of row numbers has a list length > 0 and then use item 1 of that list as the row number for the delete row.
