CleanTable - Copy Tables to Excel & Sheets

Easily detect, clean, and copy web tables into spreadsheets without broken formats or currency symbols.

CleanTable is a lightweight, privacy-friendly browser tool designed to detect, clean, and transfer web tables directly into your spreadsheets. Copying tabular data from web pages often results in numbers treated as text due to currency signs, misaligned columns caused by merged cells, or broken layouts from hidden line breaks. CleanTable automates the entire sanitization workflow right inside your browser. KEY HIGHLIGHTS • Universal Detection: Recognizes standard HTML table elements as well as modern data grids built with container divs and CSS Grid or Flexbox styling. • Cell Alignment Resolver: Automatically calculates coordinate matrices for colspan and rowspan elements to prevent jagged or offset rows when pasting. • Numerical Value Sanitization: Strips currencies and metric units while retaining mathematical signs, ensuring calculation formulas work right away without manual editing. • Number Separator Standardization: Identifies and harmonizes thousands and decimal delimiters to match your spreadsheet regional configuration. • Invisible Character Purging: Removes non-breaking spaces and cell carriage returns that commonly distort clipboard pasting. • Instant Export: Copy structured data to your clipboard for direct pasting or download standalone files in spreadsheet and structured data formats. 100% CLIENT-SIDE PRIVACY All parsing and cleaning routines run entirely in-memory on your local machine. No table content, credentials, or browsing activities leave your device.
