I want to import the data in .xlsx format

i have tried to import data in .xlsx format but it is not importing,so please help me

.xlsx is supported, but very often will fail if the required columns are incorrectly structured or if required pieces are missing. I cannot comment on the v11 import, as I am on v10, but I find it is best to create at least one item as required and export a template WITH data…then fill in the import data on that template, and import it back in.
Also, make sure that you create the referring items before importing (eg. if you plan to import a lot of products into a category, the category MUST exist before you try the import)
