Easily Resolve Spill Formula Behaving As in Office

When Office stops working as expected, start with the shortest official checks before you reinstall anything.

Problem Description: Spill Formula Behaving As

Got a bit of a big formula and it's not behaving at all as I'd expect, or as it does when taken in smaller chunks as a test for the final version. Not sure if it's a bug I'm running in to or my formula not being written correctly. The last thing I do is use a bycol() to merge multiple rows into 1, but it's giving me the answer over the same number of rows as the input to the bycol() which I thought wasn't what it should be doing. This is the result I'm getting;  I am baffled why bycol() is giving 4 rows as an answer. I've tried to post the contents of cell A2 but it keeps rejecting the edit as me not being authenticated or when I tried to include it in the original post it flat out refused to let me post at all... not at all sure what's going on there... will it let me post it as a picture?  Removing that last line of hstack() and using tmp in the last bycol() gives me this (column headings edited accordingly);  and as you can see the last column is now formatting correctly and not as #N/A. If I change that last bycol() to simply output tmp, then this is the result;  As you can clearly see, tmp is 4 rows. I'm trying to get the multiple rows from this to output into one row so I can use 1 row per "customer" as a summary line, but obviously that's not working the way I'd expect it to. Also having column A be the date for the "End of the week it's calculated for" would also be great without losing the last column as that's going to be for if a customer changes their order and I can see when to go from old order to new order.

Quick Answer for Office Won't Complete Task

Follow the recommended Microsoft steps below for excel & data problems, then retry the original task.

Likely Causes Behind Common Excel Triggers

• The Microsoft account or license context may not match the purchase or device.

• Cached credentials, outdated builds, or damaged local components can trigger excel & data problems.

• A file-specific corruption or add-in conflict can mimic a broader application failure.

Recommended Solution: Restoring Office After Errors

When to use this: Apply these steps when the symptoms match and you can access the relevant Microsoft account or administrator.

1. Record the exact error message, Office version, and operating system.

2. Retry from a trusted device with the correct Microsoft account.

3. Contact Microsoft Support or your administrator if the issue persists.

Alternative Solutions for Broader Excel Workarounds

1. Test the same action in a private browser session or a new blank file to isolate account vs file issues.

2. Capture exact error text and screenshots before contacting Microsoft Support or your administrator.

Working with WPS Office: Using WPS While Office Is Unavailable

WPS Office cannot replace Microsoft account, activation, or cloud fixes for this scenario. It remains one of the best free Microsoft Office-compatible alternatives for opening and editing local files.

1. Download and install WPS Office from the official website.

2. Open local Word, Excel, PowerPoint, or PDF files in the matching WPS app.

3. Save a working copy locally while Microsoft-side issues are resolved.

4. Return to Microsoft Office after the primary fix succeeds.

If you need a practical local workspace in the meantime, try WPS Office.

Prevention Tips for Avoiding Repeat Excel

• Keep one primary Microsoft account for subscriptions and Office sign-in.

• Install updates for Office and Windows before retrying failed workflows.

• Back up important files before repair, reset, or reinstall actions.

• Document exact error messages before the next troubleshooting attempt.

FAQs About Spill Troubleshooting FAQ

Can WPS Office fix this excel & data problems issue directly? Only when the WPS steps match the formatting or file task. Account, activation, and cloud issues stay on the Microsoft side.

Should I reinstall Office before trying these steps? Not first. Confirm account, license, and the exact error before reinstalling.

What should I send to Microsoft Support? The affected account email, device type, Office version, exact error text, and screenshots with personal data hidden.
