How PDF Text Extraction Works

PDF files do not naturally understand paragraphs; they store character glyphs with coordinates (X, Y). When an ATS extracts raw text, it sorts glyphs by coordinates. If a page has two columns, the parser frequently reads line 1 of column 1 followed immediately by line 1 of column 2, destroying your sentence structure and dropping your qualifications.

Frequently Asked Questions

Are borderless invisible tables safe to use for alignment?

No. ATS parsers still evaluate table boundary tokens regardless of border visibility. Use standard tab stops and margins instead.
