Sorry for my English, I know it's very bad :)

I need a utility or macros that can convert all frames in document to
equivalent textboxes.

I will attempt to explain why this necessarily to me.
We are using Crystal Reports 8 for reporting. Sometimes users want to
export report in a word document and edit it. In this case Crystal
presents each element of the report as the frame. You will imagine
multi-page invoice with 1000 frames. Introducing changes in this
document (delete or add some positions) is practically impossible.

Frames suppose work with them only on one for time. I need multiple
selection. Texboxes allow this feature. I think they solve my problem.

PS: I know that textboxes doesn't have all frame's features. It
arranges me.
