I am attempting to import a custom theme file I created and I get the error:
Error importing theme file
There was a problem importing your theme file. Please try again or choose another file.
I can switch to themes downloaded from the custom theme gallery just fine but whenever I try to import one that I have made I receive this same error. I have no idea what I am doing wrong? I am saving my custom themes as JSON files on notepad++. I have also tried taking successful custom themes and simply editing them with my desired colors which still results in this error.
Solved! Go to Solution.
@Anonymous,
You miss "#" for some data colors in your JSON file, please use the following JSON instead.
{ "name":"ArK2", "dataColors":["#ffd809", "#3cb371", "#bab76d", "#962222", "#519488", "#26fd2c", "#ffffff", "#d79212", "#c5a236", "#d1d1d2", "#00ff00", "#057b10"], "background":"#ffffff", "foreground":"#f2f2f2", "tableAccent":"#5bd078" }

@Anonymous,
I can't reproduce your issue, do you use the latest version of Power BI Desktop(2.49.4831.521)? Could you please share your JSON file to us?
Regards,
Lydia
Yes I am on the latest version of Desktop.
This is what I have on the file:
{
"name": "ArK2",
"dataColors": [ "#FFD809", "#3CB371", "#BAB76D", "#962222", "#519488", "#26FD2C", "#FFFFFF", "#D79A12", "C5A236", "D1D1D2", "00FF00", "#057BE0" ],
"background":"#FFFFFF",
"foreground": "#F2F2F2",
"tableAccent":"#5BD078"
}
Thank you for your time
