Dear Pravin Karne
Good day and a warm welcome to the Q&A forum!
Based on your information and after thorough research and testing, I regret to inform you that using a Text column in place of a People or Group column to filter items based on the current user is currently not feasible in SharePoint. I also explored the use of Calculated columns to achieve the desired outcome, but unfortunately, this method does not provide dynamic filtering based on the logged-in user.
I'm truly sorry we couldn’t achieve the desired result through these methods.
At this point, the most effective and reliable workaround would be to use Power Automate. With it, you can automatically capture and store the creator’s email in a text column at the time of item creation, which then can be used to configure a filtered view using JSON formatting or other logic.
However, in the Q&A forum, we are currently unable to determine the most precise solution for this specific case. For more advanced and tailored support, I highly recommend reaching out directly to Microsoft Power Platform Community Forum Thread. You can get more professional help; there will be very professional people to tell you about the steps on how to realize this function.
We hope this information is helpful and sincerely appreciate your understanding. Please let us know if there’s anything further, we can do to support you
