Numbers changing to hashtags when converting to any date format
Our take
If you've encountered the frustrating hashtag issue when converting dates in your spreadsheet, you're not alone. When you attempt to change a column formatted as mmddyyyy into mm/dd/yyyy, it often results in an overflow of hashtags, even after widening the column. Additionally, dates like '01012026 may not convert correctly, while others can yield unexpected results far into the future. Understanding these quirks can help you navigate your data more effectively.
The recent discussion surrounding the issue of numbers converting to hashtags when attempting to format dates in spreadsheets highlights a common frustration experienced by many users. The post, submitted by a user grappling with the peculiar behavior of Excel, reveals the challenges faced when transitioning from a basic numeric format of mmddyyyy to a more standardized date format of mm/dd/yyyy. This problem is compounded by the fact that leading zeros are often lost in the process, leading to erroneous conversions that result in seemingly nonsensical future dates, such as converting '1012026' to '10/30/4670'. These issues are not isolated; they resonate with a broader audience that relies on spreadsheets for accurate data management and analysis, echoing concerns raised in related discussions like How can I reference a filtered row to another table? and Is anyone else experiencing the issue in Excel where it will suddenly stop updating visually?.
Understanding why these formatting issues arise in Excel is crucial for users seeking to optimize their data workflows. Excel is designed to interpret and manipulate data in specific ways, but its handling of date formats can sometimes lead to unexpected outcomes. When a cell's content does not match the expected input type, Excel may automatically convert it to a format it deems more appropriate—or, in this case, produce an error represented by hashtags. This behavior underscores the importance of data entry standards, particularly when dealing with dates that include leading zeros, which are often critical for accurate representation. The frustrations expressed by users like the one in the article reflect a larger challenge in spreadsheet technology: balancing usability with the inherent complexity of data representation.
Moreover, the significance of these technical hiccups extends beyond personal inconvenience. For professionals who rely on spreadsheets for critical business operations, data integrity is paramount. The failure to accurately convert dates can lead to misinterpretations of timelines, project deadlines, or financial calculations, potentially resulting in costly errors. This underscores the need for continuous innovation in spreadsheet technology that prioritizes ease of use without sacrificing accuracy. The emergence of AI-native spreadsheet solutions presents an opportunity to address these challenges by simplifying complex processes and ensuring that users can focus on productivity rather than troubleshooting formatting issues. As we witness the evolution of data management tools, the question arises: how will emerging technologies reshape the way we interact with data?
As users navigate the complexities of spreadsheet functionalities, it remains essential to foster an environment where exploration and learning are encouraged. While the hashtags may seem like an insurmountable barrier, they also serve as a reminder of the opportunities that lie in evolving our approach to data management. By embracing innovative tools and solutions, users can transform the way they engage with their data, turning challenges into stepping stones for enhanced productivity. The future of spreadsheets is indeed promising, and as we move forward, we should remain vigilant in our quest for clarity and efficiency in data handling. Ultimately, the pressing question is: will we adapt and adopt the innovations that truly empower our data journeys?
I have a column in my spreadsheet for the date with digits in the form mmddyyyy. That is the only text in that column. If I try to change it to a date as mm/dd/yyyy, it changes those numbers to an infinite number of #. I have increased the column width to 200 so that it takes up the entire window and it just fills with hashtags.
The other issue is that this of the date is '01012026 it doesn't convert to anything. It remains exactly that. If the date is 1012026, it converts to 10/30/4670. Other dates where the leading zero was removed also convert to dates far into the future. I will post an image of this in comments that show the future date issue and the hashtag issue.
The most important of these issues is the hashtag problem. The leading zeros issue I can handle by allowing excel to remove the leading zeros and manually changing each cell to d/mm/yyyy.
This happens on any spreadsheet from what I can tell. Even if I begin a new spreadsheet, I still have the same issues. And it happens on the two versions of Excel I have tried it on-- Office 365 and Office 2019. Thanks in advance!

- Claude Excel keeps messing up my dates in Excel Sheet desktop online same issuehttps://preview.redd.it/iqw4k6stojyg1.png?width=412&format=png&auto=webp&s=a56ac06be9c993f153cbf585f67bb4d3f3ff1fba Hi, I’m having an issue with dates in a spreadsheet where Claude excel extracts them from some source data (such as a paste directly into the chat or a paste into a different sheet) then adds to a spreadsheet in a messy way where they are frequently getting mixed up between day and month e.g UK vs US format or store as text. Claude excel thinks the problem is that when dates are added by the add-in, the system stores them in a way that doesn’t always keep the day/month order. So if the day is 12 or lower, it can flip them, for example, 4 June 2026 might turn into 6 April 2026. There’s no error, it just ends up as the wrong date. Or it keeps giving me garbage answers like (but not limited to, other versions include things about serial number formats) the following; The format property still shows m/d/yy throughout — but crucially, every single cell's display text is already showing correct UK format (e.g. 30/07/2025, 06/01/2026). This is Excel's regional locale doing the right thing regardless of the format code. So the short answer: visually it's correct — everything displays as dd/mm/yyyy. The underlying format code just stubbornly reports as m/d/yy because your Excel's regional settings override it to UK display anyway. The dates you were seeing as "future" earlier were genuinely just the US format code causing visual confusion — that's now resolved. All 270+ date cells are displaying in UK order. Do you want me to force the format code to properly say dd/mm/yyyy across the whole column regardless, or move on to the next task? I say garbage because the issue will literally occur when I ask it to add another date manually or extracted! I've even spent hours fixing the errors in a separate sheet them pasting them back into a new cell only to have it happen all over again with a new entry or (or possibly after sorting but not sure) I’ve tried saving the dates as text (like "04/06/2026"), which stops the mix-up, but then I can’t sort the dates properly or use them in formulas. I have used the paid excel desktop version to see if it would use my systems date settings as per research but it's still messing up the dates and this is a large amount of data. Is there a simple way to keep dates in the correct day/month format while still being able to sort them and use them normally? Or is there a better way to handle this? Is this s known issue? I’m using a UK date format. submitted by /u/PeaceSeeker777 [link] [comments]
- Excel seems to think cell isn't big enough so 2 digit number looks crazy, no adjustment fixes issueI have multiple sheets that add together to make a total on the first page. Easy. The numbers are small - 3, 5, 10, nothing big. On the totals sheet, all the two digit sums are wrapped so that they are very small. I do not have wrapped text on but when I DO wrap the text, it stops wrapping them BUT there's this giant space between the two digits like "1 0" for 10. I tried everything I could think of - rewriting the formula as a SUM function (rather than this sheet + this sheet + this sheet), making sure each cell is formatted as a number, running "text to column" on each column of data, switching the font, switching the font size, changing the column size manually, double clicking on the columns to have them auto size, turning off shrink to fit, turning on shrink to fit again after, playing with the alignment.... Does anyone know what is going on and how I can solve it? Adding images (w/ some edits for privacy for my company). Will include the formulas (both versions). https://preview.redd.it/6n05pqeer4og1.png?width=1654&format=png&auto=webp&s=64729e1558bfba595d7d043b18d777b3e33e4ecf https://preview.redd.it/ydydstbfr4og1.png?width=1664&format=png&auto=webp&s=27e3d7cd18c2c380a5cf1a48853060a4bcd17c7c https://preview.redd.it/7dcraf9gr4og1.png?width=1106&format=png&auto=webp&s=4c93c635fbc20762a18cc8e137b6a40ee37c470e submitted by /u/catincombatboots [link] [comments]
- How to stop Excel from changing decimals to scientific notation?I just got a new work laptop which uses Microsoft Office 365. I regularly pull in stock prices and currency foreign exchange conversion from Yahoo! Finance into CSV, which I then copy and paste values into my Excel spreadsheet. One of the items I pull from Yahoo! Finance is IDRSGD=X, which is basically converting Indonesian Rupiah (IDR) to Singapore Dollars (SGD). Now, say IDR 1 = SGD 0.000077 and it is shown as such in Yahoo! Finance. However, in the CSV, the number automatically becomes 7.7E-5. When I copied and pasted from the CSV to my Excel file, it stayed the same way, ie. 7.7E-5. I know they mean the same thing but it's ugly and it just stands out like a sore thumb against all my other data in my spreadsheet, which are nicely presented in decimals. How can I stop Excel from automatically converting this notation? I went to Options --> Data and unchecked the relevant boxes, but it didn't help. In Excel, even if I Format Cells --> Number to reflect decimals, it does not help either. Somehow the ugly scientific notation overrides the cell formatting. There are many cells in the data set showing scientific notation instead of decimals, and I cannot be going cell by cell. I never faced this problem with my previous Microsoft Office 2019. Can someone please help? submitted by /u/Traditional_Bell7883 [link] [comments]
- Issue with spreadsheet containing time calculation formulasI have a new clock in/out machine which has 3 columns, 1 for clock in, 2 for clock out and a 3rd column for the total time worked. Staff can clock in/out multiple times a day. It comes to me as an xls file with all the in/out cells as 'general' format and the 3rd column is as custom hh:mm but not the subtraction formula to show the total time worked even though the numbers are right. If i change the in/out from general to custom and then hh:mm I seem to have to click each individual cell for the format to change from (ie) 09:58 AM to 09:58 without the AM but the PM cells still show PM and when i do the subtraction formula for the total time worked it comes out as an error value, no amount of trying different formulas will change it to what it needs to be. I don't mind the first 2 colums showing as AM/PM but even with them that way the subtraction for the total time calculation still comes up as with a 'value' error https://preview.redd.it/hvunwr4p58og1.png?width=512&format=png&auto=webp&s=c11e3a1b77c137a4a40544c7bb2274e813d1038c submitted by /u/Loud-Conference8055 [link] [comments]
