How to input chapters without newpage?

Question

I have a following problem. In my main .tex I use this code:

%-----<<< MAIN MATTER >>>-----
\mainmatter                                                     %start arabic pagination from 1
\autohdr                                                                                %automatic headers for main matter
\input{02_Mainmatter/01_Intro.tex}              %input field
\input{02_Mainmatter/02.tex}
\input{02_Mainmatter/03.tex}
\input{02_Mainmatter/04.tex}
\input{02_Mainmatter/05.tex}
\input{02_Mainmatter/99_Concl.tex}
\clearpage
%-----<<< -------- >>>-----

The problem is that each chapter starts on a new page. Look:

How can I make every chapter to start below the last chapter? Without blank spaces? Thanks a lot.

EDIT: I tried to change \chapter to \section but it totally destroyed my content:

EDIT2: Here is the whole code:

that is unrelated to \input, in most document classes \chapter headings are defined to start a page, but that depends on the docuemnt class which you have not shown — David Carlisle, Sep 13 '21 at 09:47
simpler would be to use a different document class with \section as the top level not chapter — David Carlisle, Sep 13 '21 at 09:48
@DavidCarlisle thank you for your answer, see my edit please. — vojtam, Sep 13 '21 at 10:13
you have still not shown any relevant code. you have 0. in front of the section numbers because you are using a book-level document class that numbers sections within chapters. If you used an article-level document class eg \documentclass{article} then \sectionis the top level and you have no 0. and no page break. But you have not provided any information about your document so impossible to say what to change. — David Carlisle, Sep 13 '21 at 10:24
as I say use \documentclass [a4paper,12pt]{article} instead of \documentclass [a4paper,12pt]{report} unrelated but are you really using the legacy 8 bit encoding \usepackage[cp1250]{inputenc} most editors, and latex and this site all default to UTF-8 these days. — David Carlisle, Sep 13 '21 at 11:09
Maybe add the option openany to the report class. I know that it works in book and memoir, but I don't remember if it is defined in report — Luis Turcio, Sep 13 '21 at 17:05

The memoir class (a superset of book, report, and when using the article option, article classes.

\documentclass[article,...]{memoir}
...
\begin{document}
\chapter{One}  % typesets as a section
  \section{Alpha} % typesets as a subsection
... and so on
\end{document}
