How to run app script function from first row to last row with delay 5 seconds for each row

Google App Script to run app script function in Google Spreadsheet from firstRow to lastRow with delay 5 seconds

To run an Apps Script function from the first row to the last row with a delay of 5 seconds for each row, you can use a loop to iterate through each row of data and use the Utilities.sleep() method to pause the script execution for 5 seconds before processing the next row.

Here’s an example code snippet that demonstrates how to run function with delay for the whole spreadsheet column selected:

function ProcessRowsWithDelay () {
var sheet = SpreadsheetApp.getActiveSheet();
var dataRange = sheet.getDataRange();
var numRows = dataRange.getNumRows();
var values = dataRange.getValues();

for (var i = 0; i < numRows; i++) {
// Process data for each row
// …

// Pause for 5 seconds before processing the next row
Utilities.sleep(5000);
}
}

In this example, we first retrieve the active sheet and the range of data in the sheet using the getDataRange() method.

We then get the number of rows in the data range and the values in the range using the getNumRows() and getValues() methods, respectively. We then use a for loop to iterate through each row of data and process it as needed. In the loop, we include a call to Utilities.sleep(5000) to pause the script execution for 5 seconds before processing the next row.

Note that if you are processing a large amount of data, you may need to consider using batch processing techniques to avoid hitting execution time limits.

How to use batch processing to retrieve the values and prevent the script from exceeding execution time limits

To include batch processing for processing data in the range A2:A1000, you can use the getRange() method to retrieve the specific range and then use the getValues() method to retrieve the values. Then, you can use a batch processing technique like processing the data in chunks of 100 rows at a time to avoid hitting execution time limits.

Here’s an example code snippet that demonstrates how to use batch processing technique:

function ProcessRowsWithDelay () {
var sheet = SpreadsheetApp.getActiveSheet();
var range = sheet.getRange(“”A2:A1000″”);
var values = range.getValues();

var batchSize = 100;
var numRows = values.length;

for (var i = 0; i < numRows; i += batchSize) {
// Process data for each batch of rows
var batchValues = values.slice(i, i + batchSize);
for (var j = 0; j < batchValues.length; j++) {
// Process data for each row in the batch
// …

// Pause for 5 seconds before processing the next row
Utilities.sleep(5000);
}}}

In this example, we first retrieve the specific range A2:A1000 using the getRange() method and then get the values in the range using the getValues() method

We then define a batchSize variable to specify the number of rows to process at a time and get the total number of rows using the length property of the values array. We use a for loop to iterate through each batch of rows, where we slice the values array to get a batch of rows and process each row in the batch using another for loop. Within the inner for loop, we process each row of data as needed, and include a call to Utilities.sleep(5000) to pause the script execution for 5 seconds before processing the next row.

Using batch processing in this way can help prevent the script from exceeding execution time limits, especially when processing a large amount of data.
