ClipboardTools – Professional Data Formatting & Conversion Tools
About ClipboardTools
ClipboardTools is a free online utility designed to save time for data analysts, developers, and database administrators. Convert spreadsheet data into Python lists, generate SQL IN clauses, transform tables to JSON arrays, and format text data with just a few clicks. All processing runs client-side—your data never leaves your browser.
How It Works
ClipboardTools uses intelligent data parsing to transform your spreadsheet columns into properly formatted code. Simply copy data from Excel, Google Sheets, or any spreadsheet application and paste it directly into the input area. The tool automatically detects whether your data contains single or multiple columns, identifies data types (strings vs. integers), and applies smart formatting rules.
Step 1: Paste Your Data
Copy a column from Excel or Google Sheets and paste it into ClipboardTools. The tool accepts newline-separated values, pipe-delimited data, and tab-separated multi-column tables.
Step 2: Configure Options
Choose your output format (Python list, SQL IN clause, JSON, CSV, or Markdown), enable duplicate removal, adjust quote styles, and apply transformations like case conversion or leading zero handling.
Step 3: Copy Result
Press Ctrl+Enter or click the Copy button to copy the formatted output to your clipboard. Paste it directly into your Python script, SQL query, or configuration file.
Unlike server-based converters, ClipboardTools processes everything in your browser using JavaScript. This means faster performance, complete privacy (your data never leaves your device), and no file size limits. The tool is particularly useful for database administrators building WHERE clauses, Python developers creating list literals for pandas filtering, and analysts preparing data for API requests.
