Hi @Jyoti Rajpurohit
As described here: Concurrency, looping, and debatching limits, for Low plans, the highest number of array items that a "apply to each" loop can process is 5000 while the number is 100000 for other plans.
Flows have different limits depending on their performance profile. There are five possible values, depending on the flow owner's plan.
Since the number of items in your excel exceeds 5000 and you may have a Low plan, this issue is caused by the limit of the “Apply to each”action. As per my knowledge, I’m afraid there is no workaround to such threshold issue unless you divide the large excel sheet into several small ones.
Also, this forum is dedicated to SharePoint related issues and I am not an expert on Power Automate Flow. You can raise a new thread in Power Automate community. Experts there will give you professional suggestion.
