How Can I Optimize Google Apps Script Processing Time to Avoid Slowdowns?

Optimizing Processing Time in Google Apps Scripts

Problem:

Excessive processing time in Google Apps scripts, particularly due to repeated use of getValue and setValue methods for range objects.

Description:

To reduce the number of calls to Google's servers and minimize the alternation of read and write operations, consider using the following optimizations:

Minimize Calls to Services:

• Move operations that can be performed within Google Apps Script itself to avoid costly network requests.

Look Ahead Caching:

• Take advantage of Google Apps Script's built-in cache by minimizing the number of reads and writes.

Minimize Alternating Read/Write:

• Avoid alternating read and write operations, as this hampers the effectiveness of look-ahead caching.

Use Arrays:

• Read data into an array with a single command and perform operations on the array, then write the data back to the sheet with another single command.

Example:

Here's an example of how to optimize the script provided:

Original Slow Script:

for (row = 0; row < lastRow; row++) {
range1 = s.getRange(row + 1, 1);
cellValue = range1.getValue();

if (dash === '-' &amp;&amp; offset3) {
s.getRange(row + 1, 1, lastRow).offset(3, 0).moveTo(range1.offset(4, 0));
};    
}

Optimized Fast Script:

const lastRow = s.getRange("A:A").getLastRow();
const range1 = s.getRange(`A1:A${lastRow}`);
let cellValues = range1.getValues();

cellValues.forEach((value, index) => {
if (value.startsWith("-") && cellValues[index + 3]) {
range1.getRange(index + 1, 1, lastRow).moveTo(range1.offset(index + 4, 0));
}   
});

By implementing these optimizations, the script significantly reduces the number of calls to services and streamlines the read/write operations, resulting in faster processing times.
