Q: Whether can I extract the central points while converting the text dataset into point dataset?

A: Yes, you can. Firstly, you need to open the attribute table of the text dataset, select all records in the attribute table, right click and save them as a tabular dataset. In the tabular dataset, you can find fields for bounds of all text objects: SmSdriN, SmSdriS, SmSdriW, SmSdriE. Create double-precision attribute fields X, Y, and update the column with following formulas: X= W+E/2; Y=N+S/2. Then convert attributes to points using field X and Y as coordinates X and Y.
