I removed Text Boxes, Clip Arts, Shapes but no luck still got the same error.

Also removed formulas but error remained same. Followed all possible ways to get rid of this error and checked for all possible root causes mentioned in above error but did not get success.

Finally found one column using a formula “SUMPRODUCT” and it was referring another excel sheet.

Copied data of that column pasted it as a value and removed formula.
