Resume Formatting Checker

The formatting problems that are invisible on screen and fatal in a parser.

  • Deterministic — the same document always gives the same result
  • Every finding quotes the line of your resume that triggered it
  • Parsed in memory and discarded. Never stored, never trained on

Deterministic analysis. Nothing is uploaded to a model, and your document is not stored.

What this tool gives you

  • Whether the document is text-based or an image-only scan
  • Table and multi-column layout detection
  • Every date format in use, and whether they are mixed
  • Bullet-character consistency and unusual glyph detection

How it works

  1. Add your resume

    Upload a PDF or DOCX resume, or paste the text directly. Nothing is stored — the analysis runs on the document you submit and the file is discarded.

  2. The engine analyses it

    A deterministic engine reads the document and extracts the facts — structure, skills, dates, evidence. No language model is involved, so the same document always produces the same result.

  3. Read the evidence behind every result

    You get the findings with the reasoning attached: what was found, where it was found in the document, and what to change. No score arrives without an explanation.

The cruellest thing about resume formatting is that the failures are invisible. Your PDF looks exactly as you designed it. The parser, meanwhile, has read your sidebar into the middle of your third job, or has extracted nothing at all because the file is a photograph of a page.

This checker inspects the extracted text for the fingerprints of each failure mode: separator runs and wide whitespace gaps that indicate tables, repeated deep indentation that indicates columns, a suspiciously tiny word count that indicates a scan, and inconsistencies in dates and bullets that make automated reading unreliable.

Frequently asked questions

What is the most ATS-friendly resume format?
A single-column, text-based PDF exported directly from your word processor. Standard section headings, one bullet character throughout, one date format, no tables, no text boxes, no images carrying information, and no decorative icons where a word would do.
Are PDF or Word files better?
Either is fine as long as the text is real text. A text-based PDF and a .docx both parse reliably. What fails is a PDF produced by scanning or photographing a page, because there is no text in it to extract — only pixels.
Why do tables and columns break parsers?
Because extraction returns text in an order derived from the document's internal layout, not the visual one you see. Table cells and side-by-side columns come out interleaved, so your skills list can end up spliced through your work history and your dates can attach to the wrong employer.
Does using two date formats really matter?
Yes, more than people expect. A parser tuned for one shape will silently skip the others, and every skipped range is employment that vanishes from your calculated experience. Pick one format — "Mar 2021 – Jun 2023" is the most reliably read — and use it everywhere.
