How to export long formatted text from SAP to an excel Cell

I have created an object(ZMM_TXT_PD) and an ID(Y01) using se75 transaction.

With a Z program a store some lines in STXH table with object ZMM_TXT_PD and ID Y01.

These texts are very long and formmated.

Now I need another Z program in order to download all the stored texts in an excel file.

I have a program which is able to download an internal table to an excel. The problem is that

it only works with short texts. How could I download a long text that I get using READ_TEXT function

into an excel cell?

READ_TEXT returns an internal table like this:

i_tline TYPE STANDARD TABLE OF tline.

Thanks in advance.
