Google Apps Script Debug Repair

@onkarkulkarni8

Hello, I can help with your "Google Apps Script Debug Repair" project. I develop clean, maintainable PHP backends — core PHP and Laravel/Symfony, MySQL schema design, and well-structured REST APIs. For work involving php, javascript, data processing, google app engine, google chrome, debugging, api, google sheets, automation, api integration, I pay close attention to validation, security, and readable code, delivering in small, testable milestones. I provide clean commits and clear documentation. Can we discuss the specifics before I firm up the timeline? ⭐ 5.0/5 from a recent client: "it was great working with him, did whatever changes i asked him as per my need." Final timeline and cost will be confirmed in chat after a complete understanding and documentation of the project expectations in detail.

Hi, I'm an experienced Google Apps Scripts developer with experience in providing automation workflows for Google Workspace apps, including Google Sheets. I have experience in modern JavaScript features, including spread and rest operators, async and await keywords, and so on. I can help you debug and fix issues with your Apps Script. Share your Google Sheets with me with Editor-level access so I can inspect your code, find bugs, and fix them. Let's discuss your project with me.

Hi, how are you doing? I have considerable experience with Google Apps Script and Google Sheets automation, and I’ve debugged similar issues in data fetching, array operations, and sheet updates without rebuilding from scratch. I’ve worked on trading-related sheets and can quickly pinpoint where undefined values creep in and fix length and slice errors, plus ensure calculations update correctly. Let me know further if interested.

I've debugged dozens of Google Apps Script projects with similar undefined property errors and API data issues. I'll start by reviewing your code to identify where the 'length' and 'slice' errors are occurring (usually missing null checks or incorrect API response handling), then fix the data fetching logic and sheet update calculations. With your project already 90% complete, I expect to resolve these issues quickly and have your automation running smoothly within 24 hours. Happy to hop on a quick call to understand the exact flow first if needed.

Hi. I can fix the remaining errors in your Google Sheets Apps Script. The 'Cannot read properties of undefined (reading length / slice)' errors are almost always an API response or range read returning undefined before it is used - I'll add proper guards, fix the data-fetch handling, and repair the sheet update/calculation logic so it runs cleanly end to end. I work from a copy of your script (or a duplicate of the sheet) - no need to share your account credentials. Deliverable: the corrected script with each fix commented, plus a short note on what caused every error so it does not recur. Since it is ~90% done this should be a 1-2 day fix. Could you paste the script (or share a copy of the sheet) and the exact functions/lines throwing the errors? I'll confirm the fix against your data before you release payment. Thanks.

Hi, I can take this on. Those two TypeErrors (undefined length, undefined slice) almost always mean the script is trying to read a value from a cell or API response that came back empty or in an unexpected shape, so I'll trace back to where that data enters the script and add checks so it fails gracefully instead of breaking the whole run. For the API fetching issues, I'll check the request setup, response handling, and any rate limits or auth problems that might be causing gaps or bad data, then confirm the sheet updates and calculations are pulling from the corrected data correctly. Since this is fixing existing code rather than building new, I'll go through your script first to understand the structure before touching anything, then walk through each issue one at a time so I don't introduce new problems while fixing the old ones. Can have this working within 2 days, happy to share what I find as I go rather than just handing back a fix at the end.

Hi, I can debug your existing Google Apps Script and fix the remaining Sheets automation issues without rebuilding the project from scratch. The undefined length/slice errors usually come from missing API responses, empty sheet ranges, or assumptions about array shape, so I will trace the failing functions, add safe checks, repair the API fetch/update flow, and verify the sheet calculations after the fix. I can deliver the corrected script plus a short note explaining what changed and how to test the refresh safely.
