tblr is a free Chrome add-on designed to streamline the conversion of data into HTML tables. Users can easily copy data from Excel or similar applications into tblr, which then generates the corresponding HTML code for a table. The tool supports customizable delimiters for each line, making it versatile for various data formats, including CSV. Users can also decide whether to fill empty cells with spaces to prevent collapsing rows in the output table.

In addition to its conversion capabilities, tblr provides users with useful statistics about their data, such as the number of rows, columns, and empty cells. This functionality enhances the user experience by giving insights into the data being processed. Although it currently has limitations regarding the pasting of tables with line breaks from Microsoft Office Excel, the tool's potential for future updates promises to expand its features and capabilities.
