Clearly Define ObjectivesStart by clearly defining what you want the script to do. For example, "Automate updating sales data every Monday for specific cells like A2 to C100."

Organize Data StructureEnsure your data is well-organized. Specify the sheet and cell ranges involved, like "DataSheet!A2:C100".

Use Descriptive Variable NamesChoose names that make sense. For instance, instead of "x," use something like "totalSales".

Error HandlingThink about what could go wrong and add instructions. For example, "If a cell is empty, show a helpful message."

Modularize CodeBreak down your script into smaller parts. For instance, "Separate the update logic into a function called 'updateSales'."

Version ControlUse version control to track changes, like bookmarking your script. This way, you can go back if things get confusing.

Avoid HardcodingDon’t put fixed values directly into your script. For instance, "Avoid using the number '10' directly; use a variable like 'weeklyUpdateThreshold'."

Overly Complex LogicDon’t make your script like a puzzle. Break it into smaller pieces. For instance, "If your script feels like solving a big mystery, break it into smaller, solvable clues."

Excessive Script LengthScripts are like short stories. Keep them focused. For instance, "If your script is too long, think about splitting it into different chapters (scripts)."

Ignoring PermissionsMake sure your script has permission to access and change things. For instance, "Imagine your script is like a VIP pass. It needs access to the sheets; otherwise, it might get turned away."

Neglecting TestingTest your script in a safe environment. For instance, "Imagine your script is like a car. Don’t skip test drives. Test it before it hits the road (your important data)."

Overlooking DocumentationWrite down the steps and ingredients like a recipe. For instance, "Think of your script like a recipe. If someone else needs to use it, they’ll know how."
