Unable to import Fitbit data -- An error occurred with your upload. Please try again.

With reference to poster #36 - thanks for taking the time to document the process - it helped me a lot to do the same operation with Withings weight data, which I had been struggling with until now. One thing I can add:
It is definitely necessary to eliminate any duplicate date measurements. I had left a single duplicate in the data, and only when I finally spotted and removed it was the import successful.

I have had trouble importing weight data and found some solutions that worked for me. My data isn't coming from FitBit. But, I modeled the file. First, I discovered that the word "Body" must appear on the first line and the column names should be on the second line. The next thing is that neither of the 2 header lines should contain quotes. And, Garmin seems to be particularly picky about the data. I found some records where I had weighed twice in one day. I had to remove one of those records to proceed. I have not finished importing my data. If I find other anomalies, I'll post them.

Here's an example of the data layout I used.

Body
Date,Weight,BMI,Fat
"2018-07-01","183","25.5","21.80"
"2018-07-02","182.4","25.4","21.60"
"2018-07-03","183.6","25.6","21.90"
"2018-07-04","185.4","25.9","22.30"
"2018-07-05","185.6","25.9","22.20"
"2018-07-06","187.4","26.1","22.40"

I don't I have been able to load files up 2.2kb so far. I'm not sure if there is a file size limit. I have loaded files with spaces in the names, too. But, they all end with csv. I'm not sure that's important.

I am editing to state that I was able to load a 10.6 KB file.

Also, one little tip. If you happen to have a way to do date math, you can subtract the number of days between 2 dates and move through the sorted dates to see if you land on the date you expect. That will help you identify if you have replicated dates. For example, if you subtract the first day of the month from the last day of the month and you expect to get 31 days but when you navigate 31 rows in your data file and don't actually land on that date, it might help you narrow down where your dates are off. I happen to have access to a database and used this:
select to_date('02-06-2017', 'MM/DD/YYYY') - to_date('01-13-2017', 'MM/DD/YYYY') from dual
to get the number of days between 2 dates. You can probably find other ways like Excel or an online site that does that. Heck, Siri might tell you, if you ask her.

Thanks to greenawayj for post #36 I was able to clean my withings data and get the process started. It continued to fail with no progress until I used backdoc suggestion of adding the Body line. Then I could get the import to start, but not complete. So then I added the quotation marks (good thing I know regex, which made that easier!). Still failed at the end of the import.

So then I despite the file being under 10kb, since it had 240+ records back to 2009, I broke it into three separate 100 record files and was able to successfully import!

Thanks to all for the help... ironically, I got a reply from product support stating "this is something we have never supported" bwahahahaha

I've been trying all day to import my weight info (grabbed from Google Fit) into Garmin Connect, and thanks to this thread, finally managed to do so (after some trial and error formatting the file). I'm attaching the format which worked for me in case this helps someone in future:

* No quotes anywhere in the file.
* First line contains "Body"
* Requires data for Date, Weight, BMI and Fat, even though I only had weight data.

<snippet>
Body
Date,Weight,BMI,Fat
2019-01-04,77.90,0.00,0.00
</snippet>

(For what it's worth, the full file contained 173 records which imported fine.)

Hi all, I am struggling with Sleep Data import from Fitbit to Garmin.
It looks like Fitbit changed the format of export files.

Please, can anybody share the correct Sleep Data format which can be used for import to Garmin? (CSV or XLSX)
(By the way, I was able to import all steps from Mi Fit app (using Apple Health and then Fitbit), but no Sleep Data.)

Many thanks,
Jerry

Hi,
Is there a way to import Muscle, Water, Bone mass too ? Withings exports that in the csv.
I'm considering buying a Garmin scale, but if I can't import my historical data, I will just buy another Withings scale...
Thanks

For me the import worked with a combination of tips found in this thread:

Body
Date,Weight,BMI,Fat
2021-01-23,86.28,0.00,25.17
2021-01-23,86.29,0.00,23.60
2021-01-20,87.62,0.00,25.66
...

- No quotes
- Zeros where there is no data
- Duplicate dates are fine

I was able to import ~850 historical data points.
