Can't get Appendix before A on TOC, when using appendix package with titlesec and titletoc

Question

I'm writing my thesis and Appendices have to say “Anexo” before chapter letter. I tried using \usepackage[titletoc]{appendix}, but it didn't work. Also tried to comment command from titlesec and titletoc, but even with this I couldn't make it work.

Here is my MWE:

\documentclass[12pt]{report}
\usepackage[utf8]{inputenc}
\usepackage[spanish]{babel} % pone el idioma en español
\usepackage[titletoc]{appendix}
\renewcommand{\appendixname}{Anexos}
\addto\captionsspanish{\renewcommand{\appendixname}{Anexo}}
\usepackage{titlesec} 
\titleformat{\chapter}[display] 
{\large\bfseries\centering}{\MakeUppercase\chaptertitlename\ \thechapter}{1em}{\MakeUppercase}{} % Cambios en Capitulo
\titleformat{\section}{\large\bfseries}{\thesection.}{1em}{}
\usepackage{titletoc}
\titlecontents{chapter}[0em]
{\vspace{0em}}
{\normalfont\normalsize\contentslabel[\thecontentslabel.]{2em}\uppercase}
{\hspace{-2em}\uppercase}
{\titlerule[.75em]{.}\contentspage}
\titlecontents{section}[2em]
{\vspace{0em}}
{\normalfont\normalsize\contentslabel[\thecontentslabel.]{2em}}
{\hspace{-2em}}
{\titlerule[.75em]{.}\contentspage}
\usepackage[]{hyperref} % Opción para que aparesca el indice en el pdf
\begin{document}
\tableofcontents
\chapter{text}
\section{text}
\appendix
\chapter{text}
\end{document}

The output is shown in the picture, and I need to print "Anexo A":

Edit 1: I tried adding some code to manually add "Anexo #:" to the titletoc code, without good results:

\appendix
\titlecontents{chapter}[0em]
{\vspace{0em}}
{\normalfont\normalsize\contentslabel[Anexo \thecontentslabel:]{2em}\uppercase}
{\hspace{-2em}\uppercase}
{\titlerule[.75em]{.}\contentspage}
\chapter{text}
\chapter{text}

The result:

Is there a way to move the chapter title to the right, to make this solution viable?

Answer 1

Borrowing heavily from two other answers on the site

• Unexpected interaction of titletoc and appendix?
• Properly aligning TOC entries using titletoc

The following seems to do what you want:

\documentclass[12pt]{report}
\usepackage{etoolbox}
\usepackage[spanish]{babel} % pone el idioma en español
\newlength{\toclabelwidth}
\setlength{\toclabelwidth}{2em}
\addto\captionsspanish{\renewcommand{\appendixname}{Anexo}}
\usepackage{titlesec,titletoc}
\setcounter{tocdepth}{3}
\titleformat{\chapter}[display] 
{\large\bfseries\centering}{\MakeUppercase\chaptertitlename\ \thechapter}{1em}{\MakeUppercase}{} % Cambios en Capitulo
\titleformat{\section}{\large\bfseries}{\thesection.}{1em}{}
\makeatletter
\appto\appendix{\addtocontents{toc}{\setlength{\toclabelwidth}{5em}\gdef\protect\@chapapp{\protect\appendixname}}}
\appto\contentsfinish{\gdef\@chapapp{\chaptername}}
\makeatletter
\usepackage{titletoc}
\titlecontents{chapter}
[\toclabelwidth]
{\normalfont\renewcommand\chaptername{}}
{\contentslabel[\@chapapp~\thecontentslabel\quad]{\toclabelwidth}\MakeUppercase}
{}
{\titlerule*[.75em]{.}\contentspage}
\makeatother
\titlecontents{section}
[4em]
{}
{\normalfont\normalsize\contentslabel[\thecontentslabel.]{2em}}
{\hspace*{-2em}}
{\titlerule*[.75em]{.}\contentspage}
\begin{document}
\tableofcontents
\chapter{text}
\section{text}
\subsection{text}
\appendix
\chapter{text}
\section{appendix}
\subsection{appendix}
\end{document}
