Run Ansible Task in localhost instead of inventory host

I need to check one file (/tmp/test.html) exist on localhost and if it exist execute the other tasks. Can you please help to run this first task (name: Check exist and copy) in localhost(workstation).

localhost: workstation remotehost: servera,serverb

Below is my playbook.yml

---
- name: Check exist and copy
  hosts: all
  tasks:
  - name: check if file is exists #need to execute this task in workstation
    stat: 
     path: /tmp/test.html
    register: file_present

  - name: copy to taggroup 1
    copy: 
     src: /tmp/test.html 
     dest: /tmp/dest1.html
    when: file_present.stat.exists == 0 and inventory_hostname in groups ['taggroup1']

  - name: copy to taggroup 2
    copy: 
     src: /tmp/test.html 
     dest: /tmp/dest2.html
    when: file_present.stat.exists == 0 and inventory_hostname in groups ['taggroup2']

Q: "Check file /tmp/test.html exists on localhost."

A: Module stat is not needed when paths are tested at localhost. For example, the play will fail if the file /tmp/test.html does not exist, and continue the play otherwise

- hosts: all

  vars:

    my_file: /tmp/test.html

  tasks:

    - fail:
        msg: "[ERROR] {{ my_file }} does not exist."
      when: my_file is not exists
      delegate_to: localhost
      run_once: true

    - debug:
        msg: Continue play.
      run_once: true

Try following

---

- name: Check exist and copy
  hosts: all
  tasks:
  - name: check if file is exists #need to execute this task in workstation
      stat: path=/tmp/test.html
    register: file_present
    delegate_to: localhost 

  - name: copy to taggroup 1
    copy: 
     src: /tmp/test.html 
     dest: /tmp/dest1.html
    when: file_present.stat.exists and inventory_hostname in groups ['taggroup1']

  - name: copy to taggroup 2
    copy: 
     src: /tmp/test.html 
     dest: /tmp/dest2.html
    when: file_present.stat.exists and inventory_hostname in groups ['taggroup2']

Try the following:

  hosts: all
  tasks:
  - name: check if file is exists #need to execute this task in workstation
    stat: 
     path: /tmp/test.html

  - name: copy to taggroup 1
    copy: 
     src: /tmp/test.html 
     dest: /tmp/dest1.html
    when: file_present.stat.exists and inventory_hostname in groups ['taggroup1']

  - name: copy to taggroup 2
    copy: 
     src: /tmp/test.html 
     dest: /tmp/dest2.html
    when: file_present.stat.exists and inventory_hostname in groups ['taggroup2']

See the docs.

You can use delegate_to: to run a task on a different machine than the current ansible_host.
