LaTeX no hyphenation and justification in book class like in Microsoft word

Question

There have been already several questions on this point, but still I could not find what I am looking for. I am working with book class and compiling tex file with LuaLaTeX engine. The packages babel, fontspec are also loaded. I am looking for

1. Justification of paragraph text like in Microsoft word. The lengthier space between words is okay like it is done in Microsoft word.
2. No hyphenation for entire content of the book.
3. Uniform spacing between sections, subsections, paragraphs etc.

What I have tried so far is this.

1. Setting \hyphenpenalty to 1000. It causes extra white-space between sections, subsections, paragraphs etc.

2. \usepackage[none]{hyphenat} This causes words going out of margins. I am using geometry package with custom margins.

3. \usepackage[none]{hyphenat} with \sloppy macro. It causes extra white-space between sections, subsections, paragraphs etc.

4. \usepackage[english=nohyphenation]{hyphsubst} also does not work.

The following is the MWE. The overleaf link.

\documentclass[fontsize=12bp,twoside,a4paper]{book}
\usepackage{fontspec,blindtext,setspace,scrextend,longtable,booktabs}
\hyphenpenalty=10000
\usepackage[hmargin=2.54cm,vmargin=2.54cm]{geometry}
\setmainfont{Times New Roman}
\setstretch{1.42}
\begin{document}

\chapter{Test}
some text some text some text


    \begin{longtable}{ccp{12cm}}
    \toprule[1.2pt]
    \textbf{A} & \textbf{B} & \textbf{C} \\
    \midrule
    a & b & \blindtext \\ \midrule
    a & b & \blindtext \\ 
    \bottomrule[1.5pt]
    \caption{Some Caption}
    \label{tbl:sometbl}
    \end{longtable}
    
    \blindtext[2]
    
    \subsection{Some Section}  \blindtext
    
    \subsection{Some Section}  \blindtext
    \end{document}

I have also attached the screenshot of some part of second page. I understand the fact that it may not be in the spirit of LaTeX to do some ugly formatting. However, sometimes we have these requirements posed by the institute or some journal. The problem is to have justified text in paragraph like Microsoft word and no hyphenation. Any help would be quite helpful. Thank You.

Answer 1

If you disable hyphenation then naturally you will not get publication quality typesetting, but you can make some adjustments to compensate.

Add \sloppy to allow horizontal white space to stretch more, and add microtype to enable micro adjustments to character widths to reduce the amount of white space stretching needed.

The vertical space issues are unrelated, you can add \raggedbottom so any excess vertical space does not cause spaces mid-page to stretch.

Answer 2

I will try to address the particular issues that the person is experiencing. LaTeX can be challenging for new users.

No hyphenation for entire content of the book.

You can discourage the hyphenation of words at the end of a line via \hyphenpenalty. The maximum penalty is 10000 so \hyphenpenalty=10000 would prevent almost every hyphen. Of course, the spaces between words may have to be stretched more in compensation so this would likely require a larger value for tolerance or emergencystretch.

Uniform spacing between sections, subsections, paragraphs etc.

The standard way to adjust spacing between headings is the titlesec package. Overleaf has pretty good documentation for this:
https://www.overleaf.com/learn/latex/Sections_and_chapters
The standard way to adjust spacing between paragraphs is the parskip package. For example, \usepackage[skip=6pt]{parskip} would insert 6pts of empty space between paragraphs. Also if you want "uniform spacing" you need to use \raggedbottom instead of the default \flushbottom.

\usepackage[none]{hyphenat} This causes words going out of margins. I am using geometry package with custom margins.

If words are sticking into the margins, it means La(TeX) cannot justify the text with the given parameters without causing typographic issues that are too severe. The philosophy of TeX is that the user should fix this via reformatting, rewriting, hyphenation (I know you said you don't want this for this project), tolerance, and other parameters listed here:
