recently importation of blooger to wordpress has been disabled due to the fact that google has upgraded its OAuth 1.0 API to 2.0. so the only solution is to contact wordpress to upgrade the blogger importation plugin or do it yourself. but this is alway stressful and can be confussing to a non developer. i did some research and got a better wordpress plugin that can be used to import your blogger into wordpress in few minutes.

its called blogger importer extended which can be downloaded from https://wordpress.org/plugins/blogger-importer-extended/ It works like a charm.

Blogger Importer Extended can:

*Import posts
*Import pages
*Import tags
*Import comments
*Import images
*Import links
*Convert formatting
*Preserve slugs

Notes:

*Due to Google APIs daily quota limitations the importer can be unavailable, try later.
*Due to Google policies, Blogger API v3 are only accessible through manually approved web services, so, any imported content (posts, pages, comments, etc...) go through our web service, only public contents are processed, no private data, no anything else.
