Create a workbook Example not working

[Djone124]

Could not get the example provided in the section Create a workbook with a Base64 example to function. It is saying the property result does not exist for "event.target". The code is being run in Script Lab.

@Djone124 sorry to hear that you've run into this problem. @AlexJerabek is this something that you can investigate? Thanks!

Hi @Djone124 ,

Thanks for reporting this. If you're using Script Lab, there's a full TypeScript example for this scenario in Script Lab's samples. You'll see there's some casting to get this to cleanly compile, but the JavaScript should work anyway. Try that out and let me know if there are still problems.

That said, I should clean up the JavaScript in this sample. The type of event.target is ambiguous. According to this comment, we'll get the same behavior by calling reader.result.toString(). I'll update the code in both the docs and Script Lab to do that and avoid the need to cast.

As for the compilation error for myFile.files[0], you'll have to cast it in TypeScript. We do that in the Script Lab sample, but can't really the in the JS sample.

I'm going to open PRs in this repo and office-js-snippets for the code changes described above. Please let me know if you're able to get the sample working in Script Lab.

Hello Alex, Thank you! I was able to get the sample to work perfectly. I must have glanced right over that sample in the Samples pane in Script Lab. I really appreciate the help, Danny

Hi Danny,
I'm glad everything's working. I'm going to go ahead and close the issue, as the doc changes are in the pipeline. If you encounter any other problems while developing your add-in, please reply to the thread or create a new issue.
Thanks!
