Who wrote Ezekiel:

Although Ezekiel is only mentioned twice in the book of Ezekiel, very few people disagree Ezekiel, a priest held captive in Babylon after the second siege on Jerusalem, was the author. The book of Ezekiel is autobiographical recalling his time as a captive in Babylon and visions he received from God. The book of Ezekiel served as a message of warning and a call to repentance and faith.

The consistency in writing style, language, theme, and theology, all point to a single person as the author. Ezekiel dated each vision he received. This not only helps date the book of Ezekiel, it also suggests the author wrote the book as a journal.
