Ansible : how to read hosts from txt or CSV or JSON file

Question

I have written the below playbook to uninstall agents on linux hosts and it is working, currently its reading hosts from /etc/ansible/hosts file(hardcoded) but I want to read hosts dynamically from txt/csv/json files while running playbook, please suggest.

playbook

---
- hosts: Linux
  name: "Uninstall oneAgent on Linux hosts."
  tasks:

   - name: stop oneAgent service
     become: true
     ansible.builtin.service:
      name: oneagent.service
      state: stopped
     register: result3

   - name: Printing service status
      debug:
        msg: "{{result3}}"

   - name: "Uninstall oneAgent"
     become: true
     command: "sh /opt/dynatrace/oneagent/agent/uninstall.sh"
     register: result1

     debug:
       msg: "{{result1}}"

   - name: Declaring variable stdout_lines
     debug:

   - name: Printing Uninstallation status with stdout_lines
     debug:
