What is the problem? Please be detailed.
I have collected data about date of vaccination but all date data are shown as 00:00:0000 after exporting the data to CSV file. I have 3000 observation and it's hard to re-enter the date again .. is there any way to solve this ?
What ODK tool and version are you using? And on what device and operating system version?
What steps can we take to reproduce the problem?
let me know please if there is any way I can have these dates in my exported file What you have you tried to fix the problem?
nothing Anything else we should know or have? If you have a test form or screenshots or logs, attach here.
Are you opening the .csv file in Excel? There's a chance that it could be a formatting issue and that Excel just isn't displaying all the date data. It could be helpful to open the raw .csv file in a text editor so you can see whether the date data is there. This forum thread seems possibly related: Date format.
I was able to fill out your form, on ODK Collect v1.11.1, send it ODK Aggregate v1.4.15, download it as a CSV with the following data.
"12","312","not_vaccinated_fake_card","Wed Nov 15 00:00:00 UTC 2017","uuid:a210a087-0450-4564-af32-363ddf234e74"
Open the CSV in a text editor and see what the date looks like. https://notepad-plus-plus.org is a free and good text editor. If the date looks like the text above, the problem is with Excel. If the date does not look like the text above, then the problem is with either the client (e.g., ODK Collect) or the server (e.g., ODK Aggregate) you are using. Telling us what versions of clients and servers you are using would then be the next step.
Excel is definitely able to manage date data, and it should be able to import date data from a .csv file. It may be that Excel is importing the data correctly, but not displaying it correctly. If that's the case, you would just need to select a date format for the date column. There are a lot of Excel resources out there, but here's one article I found on date formats in Excel:
Importing to Stata is a different process from Excel. One option is odkmeta, of which I am an author. You can download odkmeta from SSC by typing within Stata:
ssc install odkmeta
Once it's installed, type help odkmeta to view the help file. One thing that odkmeta does automatically is format date, time, and datetime variables.
To use odkmeta, you first need to export your data from your server using ODK Briefcase or an equivalent process. odkmeta expects to receive raw data: don't clean the data in Excel first, as that may alter the format of the data from what odkmeta expects.
For a simple form, you might also consider importing and formatting the data yourself using built-in Stata commands.
Good , I have solved it ..let me explain here so others can see when they face the same issue..
First , when I exported the data from the odk account, I first used the steps in the article about excel date that Mathhews have attached then used the (saved as) option. My issue was that I have saved the file before doing these steps so when I tried to use the excel steps it did not work
Thanks a lot ODK group you all are amazing and so helpful
