Convert the PDF document into an Excel file where each paragraph is placed in a separate row. Create one column for the heading, another column for the subheading, and a third column for the paragraph content.

There are 130 pages.

I need a freelancer who can take a PDF document and convert it into an Excel file with a very specific structure. The conversion must detect Headings and Subheadings correctly, then break content into individual rows so that:
• Column 1: Heading (e.g., “1. Introduction”)
• Column 2: Subheading (e.g., “1.1 Scope”)
• Column 3: Paragraph / bullet point content

For example:

Row 1 → 1. Introduction | 1.1 Scope | Preliminaries – general design criteria …
Row 2 → 1. Introduction | 1.1 Scope | Sustainability objectives – environmentally sustainable …
Row 3 → 1. Introduction | 1.1 Scope | Design requirements …

Key requirements:
• Automatically repeat the Heading/Subheading for every row until the next heading is detected.
• Each bullet point or distinct line under a subheading must become its own row.
• Clean formatting (remove headers, footers, and page numbers).
• Must handle a long technical PDF without missing data.
