Hello dear community,

I will show you how to edit .csv files using Notepad++. It is very easy to mod.

Please note that not all games are made in CSV.

First of all, you need:

Notepad++ installed on your computer. Download it from here:

https://notepad-plus-plus.org/download/

WinRAR installed on your computer. Download it from here:

App Backup & Restore app installed on your Android device. Download it from here:

Understand how CSV files work. You can read about it here:

Part 1: Extract CSV files from the APK file

In this tutorial, the app "Piano Tiles 2" will be used as example.

Backup the APK file using App Backup & Restore, connect your device to your computer, and transfer the APK file to your computer

Right click on the APK file, select Open with -> Choose another app (see screenshot below):

Now click on "More apps" and look for another app on your PC (see screenshots below):

Find the path where WinRAR is installed (usually C:/Program Files/WinRAR) and click "Open". This way, WinRar will show you the content of the .apk file (see screenshot below):

Part 2: Extract .csv files

Find the .csv files inside the APK file. If you find it, select all .csv files and copy them into a path (or folder) that you can easily access (see screenshot below):

Part 3: Open .csv files with Notepad++

IMPORTANT: Do not open .csv files with Excel because it will ruin the whole .csv format.

Right click on a .csv file and select Edit with Notepad++ (see screenshot below):

the .csv file will open inside Notepad++.

exp.csv

Remember how CSV file works. I drawed red lines so you can easliy understand how it works. If you still don't understand, please read: http://creativyst.com/Doc/Articles/CSV/CSV01.htm

change them all to 9999 except Lv (see screenshot below):

This way you'll get 9999 exp after every song (see screenshot below):

Life.csv

In LifeRecovery data, change all to 3 which means the game gives you 1 life every 3 seconds, or you can change Life data to 999999 (see screenshots below):

gold.csv

Change all to 999999 to get Unlimited Coins (see screenshots below):

task.csv

This csv file is about daily rewards. Change life, gold and exp data to 999999 and claim the daily rewards to get unlimited everything (see screenshots below):

level.csv

Now this is a bit harder. You have to manually count the columns one by one to find the correct data (see screenshot below):

Example: I count up to NeedDiamond and the NeedDiamond is #8 (see screenshot below):

And in data values section, I counted up to 8 and i see there is the value "10" in NeedDiamond which means a song costs 10 diamond. Remove the 10 or replace it as 0 so it costs nothing (see screenshot below):
