Dear Employer,
I have read and understand your requirement for this project, which requires tweeting through Excel. I reckon I could execute this project successfully.
As of me, I have enough skills in MS-Excel VBA and Twitter API, and sufficient experience to provide fruitful results for this project in a better way. Additionally, I could provide Add-On to control the behavior, and option to change the twitter account. You can see my profile.
Apart from your project specifications, I would like to confirm some data. Based on the understanding, I believe, its through MS-Excel or Google Sheets. Please clarify.
Please, let me know if any details required further, and we can discuss further.
Thank you for your opportunity.
