• →Batch-convert downloaded research PDFs into searchable text files for keyword searching

📊 For analysts working with messy spreadsheets

• →Read a messy CSV export with inconsistent date formats and standardise everything to DD/MM/YYYY
• →Merge 12 monthly sales reports into one master sheet with totals calculated automatically
• →Flag rows where a value in column C is missing but column D has data (common data quality issue)
• →Build a pivot-table-style summary from raw transaction data without opening Excel at all
• →Split one large CSV into separate files by the value in a specific column (e.g. by region or category)

📋 7 real prompts that worked on my first day (copy-paste ready)

Read all files in my Downloads folder. Rename each one using the pattern YYYY-MM-DD_original-name. Don't delete anything. Show me a preview list before making any changes.

Create a simple HTML page that takes an amount and a GST rate (5%, 12%, 18%, or 28%), calculates CGST, SGST, and total, and shows the breakdown. Save it as gst-calculator.html on my Desktop.

Read the file client-data.csv in my Documents folder. Find all rows where the phone number column has fewer than 10 digits or contains letters. Save those rows as errors.csv and the clean rows as clean-data.csv.

Look at my Desktop folder. Group all files by their file extension (pdf, docx, jpg, etc.) into subfolders. Show me the plan first — don't move anything until I approve.

Create an invoice template as a Python script. It should ask me for client name, items, quantities, rates, and GSTIN. Output a formatted PDF invoice saved to my Desktop.

Read all .docx files in my Articles folder and create a spreadsheet showing filename, word count, and date modified, sorted by date. Save it as article-stats.xlsx.

Check my Photos folder for duplicate image files (same content, different names). List them in a text file — don't delete anything yet, just show me what's duplicated.

Notice the pattern: be specific, mention file paths, describe the output format, and ask for a preview before changes happen. The Claude prompting techniques guide covers the EL10 and Kill Critic methods that work inside Claude Code too.

Hardware and OS requirements

Which Claude plan you actually need — INR pricing

Route A: The Claude Desktop app (no terminal, no fuss)

This is the recommended starting point for anyone who finds the terminal intimidating. The Claude Desktop app is a regular application — you download it, install it, and Claude Code capabilities are built in.

1. 1
   Go to claude.ai/download. Download the app for your OS (Mac or Windows).
2. 2
   Install it like any other application (drag to Applications on Mac, run the installer on Windows).
3. 3
   Sign in with your Claude account. Make sure you're on the Pro plan.
4. 4
   In the app, click the "+" or "Projects" to create a new project.
5. 5
   You're ready. Claude Code features are available inside the Desktop app natively.

Route B: The VS Code extension (no terminal, more power)

VS Code is a free code editor that many non-programmers use for writing Markdown, managing files, and working with CSV data. The Claude Code extension plugs directly into it.

1. 1
   Download VS Code free from code.visualstudio.com. Install like any application.
2. 2
   Open VS Code. Press Ctrl+Shift+X (Windows) or Cmd+Shift+X (Mac) to open Extensions.
3. 3
   Search for "Claude" — install the official Anthropic Claude extension.
4. 4
   Sign in with your Claude credentials in the extension panel.
5. 5
   Open a folder (File → Open Folder) and start prompting from the Claude panel.

Route C: Terminal on Mac (if you want the full experience)

Route D: Terminal on Windows (PowerShell)

# Step 1: Enable WSL2 (Windows Subsystem for Linux)
# Open PowerShell as Administrator (right-click → Run as Administrator)
wsl --install

# Restart your computer when prompted.

# Step 2: Open WSL (Ubuntu) from Start menu
# From here, the commands are identical to Mac:

node --version           # check Node is installed
npm install -g @anthropic-ai/claude-code
claude                   # opens browser for sign-in

Common install errors and exactly how to fix them

1. CLAUDE.md — the memory file that makes Claude remember you

Claude Code has no memory between sessions by default. Close the terminal, start again, and it's forgotten everything. CLAUDE.md fixes this. It's a plain text file you create in your project folder. Anything you put in it, Claude reads at the start of every session in that folder.

# My preferences
- I am an accountant working with Indian GST and income tax
- All amounts are in INR unless otherwise specified
- GST rates I use: 5%, 12%, 18%, 28%
- My GSTIN: [leave blank, fill when needed]
- Output formats: Excel (.xlsx) for tables, PDF for reports
- Never delete any file without explicitly listing what 
  you will delete and getting my confirmation first
- When uncertain, ask me one clarifying question

2. Context windows — why long conversations slow down

A context window is Claude's working memory for a session. Every file it reads, every message you exchange, and every response it generates fills it up. Once it's full, Claude starts forgetting earlier parts of the conversation. When tasks go slowly or Claude seems confused about something it knew earlier, the context window is usually why. The fix: use /compact to summarise and clear, or start a fresh session for a new task.

3. Sub-agents — running multiple Claudes in parallel

For complex tasks, Claude Code can spin up sub-agents — separate Claude instances working on different parts of a task simultaneously. You don't control this directly; Claude decides when to use it. What matters for you: if you notice Claude saying it's "spawning" or "delegating" something, it's working efficiently, not failing. Don't interrupt it.

4. Slash commands you'll actually use

5. Permissions — when to allow, when to pause

Claude Code asks for permission before taking actions: reading a file, writing to disk, running code. Always read the permission request before clicking yes. If it says it will "delete" something, that's worth a pause. If it says it will "read" a file you recognise, approving is fine. Think of permissions like the pop-up on your phone asking an app to access your photos — you check it before tapping Allow.
