I need help converting my Excel VBA macro to Google Sheets using Google Apps Script. The macro works great in Excel, but I’d like to apply it in a Google Sheets document. It looks for a license plate number in one sheet and updates a corresponding job completion date in another sheet. Essentially, it identifies the vehicle registration in the “Valet” sheet and marks it as complete in the “Trades” sheet by entering today’s date.
Below is the VBA code that I want to translate:
function markComplete() {
var currentDate = new Date();
var plateNumber = SpreadsheetApp.getActiveSheet().getRange("B4").getValue();
var tradesSheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Jobs");
var searchRange = tradesSheet.getRange("A1:E25");
var searchResults = searchRange.createTextFinder(plateNumber).findNext();
if (searchResults) {
var targetCell = searchResults.offset(0, 18);
targetCell.setValue(currentDate);
}
}
What adjustments do I need to make for this to function correctly in Google Sheets?
the code’s mostly converted already. main issue - you’re pulling the plate from “B4” but mentioned the “valet” sheet. you need to specify which sheet: SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Valet").getRange("B4"). also, that offset(0, 18) seems way off unless your sheet’s really wide.
You’re trying to automate updating a Google Sheet using Google Apps Script, but your current approach using offset() with a hardcoded value is fragile and prone to errors if your spreadsheet structure changes. The original VBA macro worked well in Excel, but a direct translation doesn’t account for the differences in how Google Sheets handles data and sheet references. The script also lacks robust error handling.
Understanding the “Why” (The Root Cause):
The core issue lies in the reliance on hardcoded values and a lack of flexible data referencing. Using offset(0, 18) assumes a fixed column structure in your “Trades” sheet. If columns are added or removed, the target cell for the update will be incorrect, leading to errors or data being written to the wrong location. Similarly, using SpreadsheetApp.getActiveSheet() to get the license plate number means the script will only work correctly if the active sheet is “Valet”. Any change to the sheet structure or the active sheet will break your script. Finally, lacking error handling means that if a license plate isn’t found, the script will silently fail without informing the user.
Step-by-Step Guide:
Refactor for Dynamic Data Access: Replace the hardcoded sheet and range references with dynamic methods. This makes the script resilient to changes in your spreadsheet structure. Use getSheetByName() to explicitly select the “Valet” and “Trades” sheets, and use methods like getLastColumn() and getLastRow() to determine the actual data range instead of relying on fixed ranges like A1:E25.
function markComplete() {
var currentDate = Utilities.formatDate(new Date(), Session.getScriptTimeZone(), "yyyy-MM-dd"); // Format date correctly
var ss = SpreadsheetApp.getActiveSpreadsheet();
var valetSheet = ss.getSheetByName("Valet");
var plateNumber = valetSheet.getRange("B4").getValue();
var tradesSheet = ss.getSheetByName("Trades");
var lastRow = tradesSheet.getLastRow();
var lastColumn = tradesSheet.getLastColumn(); // Dynamic range
var searchRange = tradesSheet.getRange(1, 1, lastRow, lastColumn);
var searchResults = searchRange.createTextFinder(plateNumber).matchCase(false).findNext(); //Case-insensitive search
if (searchResults) {
//Find completion date column - more robust than hardcoded offset
var completionDateColumn = tradesSheet.getRange("1:1").getValues()[0].indexOf("Completion Date") + 1; //Assumes header row
if (completionDateColumn > 0) { //Check if column exists
var targetCell = searchResults.offset(0, completionDateColumn - searchResults.getColumn()); //Dynamic offset
targetCell.setValue(currentDate);
} else {
Logger.log("Completion Date column not found in Trades sheet!");
}
} else {
Logger.log("License plate not found in Trades sheet!");
}
}
Implement Comprehensive Error Handling: Add error handling to gracefully manage situations where the license plate is not found or the “Completion Date” column is missing. The updated code above includes Logger.log() statements to provide feedback in these scenarios. Consider using try...catch blocks for more robust error management. For production use, you might want to replace Logger.log with user-friendly alerts or email notifications.
Test Thoroughly: Test the updated script thoroughly with various scenarios, including cases where the license plate is not found, the spreadsheet structure is modified, and different date formats are used. Verify that the script handles these cases gracefully and provides informative feedback.
Common Pitfalls & What to Check Next:
Spreadsheet Structure: Ensure the column names in your “Trades” sheet are consistent. The script now relies on finding the “Completion Date” column by name. If this column’s name changes, the script will fail.
Data Types: Double-check that the license plate numbers and completion dates are of the correct data type in both sheets. Inconsistent data types can lead to unexpected matching issues.
Case Sensitivity: The updated script uses matchCase(false) for a case-insensitive search. Ensure this aligns with your requirements; if case sensitivity is crucial, remove matchCase(false).
Authorization: Make sure your Apps Script has the necessary permissions to access and modify your Google Sheet.
Large Datasets: For very large sheets, consider optimizing the search algorithm if performance becomes an issue.

the code’s fine, but you’ll get permissions errors on first run. Google Apps Script needs authorization for Sheets access - just click through those scary warnings. also check your license plates for leading zeros or spaces - they constantly break sheet matching.
There’s a big disconnect between what you want and what your code actually does. You said you’re finding license plates in the “Valet” sheet, but your script pulls from whatever sheet is currently active (B4 cell). That’ll break if you’re not on the right sheet.
I’ve run into this before with cross-sheet lookups. Stop using SpreadsheetApp.getActiveSheet() and hardcode it instead: SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Valet"). This way you’re always hitting the right sheet.
That offset of 18 columns seems way off unless your Jobs sheet is massive. Sounds like you just need to find the license plate and update a completion date column nearby. Check your actual column layout and fix that offset.
One heads up - Google Apps Script can be weird with date formatting. Your script might work fine but show dates strangely depending on your locale settings.
Your code has a mismatch between what you described and what it’s actually doing. You said you’re searching columns A through E, but then you’re offsetting 18 columns to the right - that puts you in column S. That’s a huge jump for a completion date column. The offset calculation is your main problem. If license plates are in column A and completion dates are in column F, you’d want .offset(0, 5) instead of 18. Check your actual sheet structure first. Also, A1:E25 might be too small for your search range. Use getDataRange() or expand the range if you’ve got more than 25 rows. The createTextFinder() method works fine, but make sure your plate numbers match exactly between sheets - Excel formatting can mess up matching in Google Sheets.
I converted similar VBA macros last year - the syntax differences are pretty straightforward. Your biggest problem is that offset calculation. 18 columns from E puts you in column W, which probably isn’t where your completion dates live. Check your actual sheet layout first. Google Apps Script handles dates differently than VBA. Use Utilities.formatDate(currentDate, Session.getScriptTimeZone(), "MM/dd/yyyy") instead of just currentDate or you’ll get timezone headaches. Ditch that fixed A1:E25 range for something dynamic like tradesSheet.getRange(1, 1, tradesSheet.getLastRow(), 5) so it grows with your data. The createTextFinder method works well but it’s case-sensitive by default. Add .matchCase(false) if you need it. Test everything thoroughly - Google Sheets handles text comparison differently than Excel sometimes.
Here’s what everyone’s missing - you’ll be stuck maintaining this script forever. Every time your sheet structure changes, you’ll need to hunt down offset calculations and range references.
I went through this exact scenario with vehicle tracking sheets at work. Started with Google Apps Script, spent way too much time debugging when someone moved columns around or added new data fields.
What you need is proper automation that handles sheet monitoring and updates automatically. Set it up to watch for changes in your Valet sheet, automatically find matching license plates in the Jobs sheet, and update completion dates without manual triggers or brittle offset calculations.
You can add proper error handling for missing plates, duplicate entries, and data validation. Plus you get real logging so you know exactly what happened when something goes wrong.
The automation approach scales better too. When you need to add more logic or connect other sheets, you don’t have to rewrite Apps Script functions.
