The Problem:
Trying to open CSV file that my app had generated kept causing the following message to appear in Excel:
Excel has detected that ‘balhblah.csv’ is an SYLK file, but cannot load it. Either the file has error or it is not a SYLK file format. Click OK to try to open the file in a different format’ , you may also get the message SYLK: File format is not valid
The solution:
After many hours of pulling my hair out trying to work it out I discovered that if you make the first letters “ID” of a text file Excel incorrectly assumes you are trying to open an SYLK file (whatever one of those is!).
Hope that helps!
PS Microsoft have a page on this now… http://support2.microsoft.com/kb/323626
I ran into this problem when creating a CSV file with the requirement that columns 1-2 of the first record – representing the first cell of the spreadsheet must contain uppercase “ID”.
I kept getting “Unable to load SYLK file…” Ichanged that to “Id” – but that was not acceptable to the program into which this file was input.
For the moment I have got around it by setting up the field as “ ID “ and seeing whther the next program is rigidly expecting :ID” in cols 1-2, or is it a “free-format field which allows for “ID” as floating characters.
One can only hope and pray!!!
waooo thanks for saving…!
Great job! TNX!

good, still helping… but after six years Microsoft has not yet solved the bug ?
Microsoft will tell you it’s a feature 🙂
Thank you Alun for sharring this info – it has saved me pulling my hair and spending many hours to figure this out….
Thank you and bless you for sharring this info.

saved me today (7/18/18)
The way to fix this for a programmer is to put the apostrophe character (’) as the first character of the CSV file. Then when Excel opens it, it won’t say, “Error: its a SYLK file gone bad”.
Thanks.
Put an apostrophe at the beginning of the first field and this irritating error goes away
Another code warrior salutes you!
Thanks ! it helped..
refering to #5 above, the solution is not for the programmer or enyone else in the world to avoid using the characters ID in a CSV header. The solution is for Microsoft the remove such a stupid hard-coded logic.
Looking at the MS knowledge base this should be fixed in the most recent versions of excel
http://support.microsoft.com/kb/323626
It’s not.
Still at 16 Feb 2017, it’s not.
Still at 25 Jan 2018, it’s not.
Still at 26 April 2018, it’s not.
Still not fixed as of today. Just ran into this exporting to Excel from a sql proc…a random piece of dumb luck I named the files starting with “ID”.
Not dumb at all! Lots of frameworks WANT you to name the key ID!!

i cant save excel file in .csv format error you cant save multiple sheet in format
how to save
plz reply me.
Hi Khandu
You can’t save a multi-sheet excel file as a CSV because csv’s don’t support multiple pages. Simply save each worksheet as a desperate CSV and name them in a sensible way for the other person to import e.g. mydata_sheet1.csv, mydata_sheet2.csv and so on
Good luck!
Alun
THANK YOU , THANK YOU , THANK YOU
Thanks!! Still useful!
Wow, 2 years and a bit on and it’s still proving useful! Glad to have helped
This didn’t help me for my requirements…
What did help was this:
—Save file as a .csv and close it.
—Right click on the .csv file and Open with>Notepad
—Go to File>Save As
—Under Ecoding: select UTF-8
—Click Save
Thanks – this fixed it for me!
This helped me as well. Thank you!
Same here — thanks!
Thank you Mitch. Life saver. And thank you Alun for starting the whole topic.
HELL YEAH!!! Thanks.
Helped again, thanks
Yup, still helping.
Thanks!
Thank you!
Still a big help. Keep this alive (Incase you were thinking that no one is using this anymore)
received the error message during import of a custom csv file about 3 minutes ago.
googled it and this article resolved it in less than 60 secs.
thanks!!!!
And there was me thinking it was my programming skills that sucked. Microsoft, as usual. Pfft. Suckers.
On a serious note, thanks for the tip. I dread to think how many circles I would have went round if I didn’t discover it.
Changing ID to lower case id should also fix the problem.
We had to change from upper to lowercase to when saving from xlsx to csv. Other wise we would get the error.
That’s useful to know! Thanks
Thank you – this helped me out as well!
You are the best ! Thank you!!!!
Thank God for Google that found this.. I was pulling my hair out on this!
Thank you!!!! You saved me much frustration.
You saved my day. Lot of thanks. I have a csv file that has a column with header=“ID”. It was giving me SYLK error. But once I changed it to “Id”, it worked like magic.
Just ran into this problem. I have cell A1 of each of my CSV files as “ID”. Would’ve never figured this out on my own. Glad this post is still available here after so many years. Thank you so much for sharing. Cheers!
Glad to still be of help
Thank you !
I’m just thinking…thank GOD for the Internet!
Just another drive by thank you. This is more helpful than the offical MS help page on this topic.
GOD , Would have never figured out this.. wasted one whole day.
Thanks mate.
Thanks for saving me hours of investigating.
I want to have your babies. I love you. Thanks
Let’s us know how that works out! Thanks!
It’s the “The file you are trying to open, ‘x.csv’ is in a different format than specified by the extension…” that gets me.
Thanks for preventing me going blind looking for obscure and non-existent unprintable characters…
Wow. I never would have guessed that was the issue. I changed the first cell from “ID” to “dbID” and now the error is gone. lol
Thanks!
This is amazing. Thanks!
This is awesome help!
Thanks a lot!
Thank you!
thank you, thank you, thank you!
wow Thanks! still not fixed I see. and still helping…………

Thank you so much. Found this and fixed the error.

Aargh! Thanks a lot – just wish I had seen your post a couple of hours earlier 😉
Wow!, thanks for your post! That helped so much!
D’oh!; thanks for the post. Very helpful
Thanks for taking away the pain – wish I’d checked your site YEARS ago. My previous solution was opening in Open Office then saving as .xls LOL
Omg — Thank You so much
Thank you, thank you, thank you!!!!!!!!!!!!!!
Thanks man!
Merci !!!!!! Thank you !!!!! You just saved the day !
Thanks a lot!
Thank you so much for that info! Even though I have spent a few hours pulling my hair – I would never have arrived at that conclusion without your input.
Thanks a bunch!
This still occurs in Microsoft Office Professional Plus 2010 (version 14.0.7173.5000), although Microsoft doesn’t admit it on their KB support page.
I dont know what is more funny, the solution or how many csv files must begin with “ID”. Thanks for post.
Thanks – your post came up in a google and most helpful. I am in the process of moving to Softmaker Office 2016 having previously used MS Office 2003. When moving back and forth I hit this problem and assumed incorrectly it was Softmaker trouble. Yes my database has ID for the first field (column) and hits this problem.

Running Excel 2016 in the year 2017 and this is still a problem that you helped me solve! Thank you!
thank’s bro , i just spend my 4 hours into this .
This article is now 5 years old and it’s still helping! Amazed MS haven’t fixed it but the occasional gift from my Amazon gift list and a few affiliate fees for adverts cover off the over 1200 visitors per month just to read this article!
Wow – I wasted 3 hours on this problem – As soon as I looked it up (finally – dumb of me to wait) your fix came up!
1st hit on google search, still an issue after all this time?
Thanks buddy. You saved a ton of time…

Thank you so much for pulling your hair out for us!
Thanks … would never have figured that out!!!
Another happy camper….I would never have worked that out myself
…A thousand thanks mate !!!! 🙂
Still helping, thanks a million!
I solved this issue with:
Application.DisplayAlerts = False
Workbooks.Open Filename:=path, Local:=True
Application.DisplayAlerts = True
Where ‘path’ is a string variable with the path where the file is.
Obviously this is a VBA solution.
I hope this help you.
Thanks! VBA Solution shared!!

OMG, thank you for saving me so much time.
You sir, are a gentleman and a scholar.
This resolved my issue so quickly!
Well done.
What a random error, but it also just happened to me !
Is there anything we can do about it ?
My CSV file needs to have “ID” as the first element.
There is no way around it.
Why do you need ID as the first field? If you are outputting to Excel then you can choose anything as your output format. If you need to then send it on from there it you could then rename it once it is in the system or output it using a macro which renames the first column.
Alternatively make ID the last column? most imports should sort it out for you?

Thank you so much for sharing this info.Very useful.

We have discovered if CSV is changed to UTF-8, the SYLK problem disapears (without change ID to Id)

This is still helping as of February 15, 2018 – four years later. Microsoft has disabled the solution page listed above. Users now get the Microsoft version of the 404 File Not Found error, so can anyone explain WHY Excel does this? Or has anyone found the new link to Microsoft’s explanation?
Thanks a bunch! That prevented me from suicide 🙂

Come on MS! This is a tiny task to fix – do it now!
Far too much monkey see, monkey do. Too clever by half! Are you aware that many people import csv files where the first cell contains ID? And they want them to be csv, nothing else.

I found another option.no need to change the column heading order title. Just open a new excel and than open the file which you would like to open (SYLK format file), it will open this time.

This post saved the day. It’s unbelievable that this hasn’t been fixed yet.
I think Microsoft would describe it as a feature not a bug…
Thanks for this so many years later!
I am quite certain that I told Excel that I was looking for text files (not slky or skly or ksly or Excel or any other type of file). Yes, I chose from a selection that Excel presented me with. I knew I wanted txt files… I chose a text file… even had a .txt extenstion… I told Excel this after it asked me… and wha??? It wants to tell me it’s a slksdksyr file?
How awful.
If Microsoft has any hand in building the AI that is suppose to rule the world one day, at least we now know we can just write “ID” on the bullets we shoot at the droids that come to farm us. They will have no defense.
Just change the first line of your address and your first name to ID.
They’ll never know who you are or where you live!
NEWEST issue: what if the file already was saved and I am trying to open it when I get this SYLK error?
I can’t get to the data to view it and fix it 🙁
Off the top of my head you could try opening it in a proper text editor like Sublime?
Or open a new sheet and open it as a datasource?
Big help. Thanks a lot.

What Connie says!
September 2018 …. still helping
I edited the csv in Notepad and changed the header row to have double quotes around all the headings, and it fixed the issue for my file. The quotes are not displayed when loaded in Excel and no warnings. Winning!
i.e.
“ID”,”Name”,”Email”
Yep, that’s another great way to fix the issue. Adding quotes means it’s just treated as a string and no preprocessing takes place. But like when people give you datasets with columns that have names with sql keywords like Select, from, where etc
Still helping…saved me many hours of troubleshooting…
Thanks a lot, you saved me many hours of troubleshooting.

Can someone try to OPEN A SECOND TIME the file, after Excel gives you errors and opens a blank file ?
Just, keep the file (excel) open and double clic the file again. What happens there ?

NEVER GIVE UP
for me it works, excel opens the file and displays its content
Well, it is 11.14.2018 and I just encountered the same issue! Oy vey!
