ATS Resume Format: Check What Your File Reveals
A practical format check using a synthetic resume fixture: inspect extracted text, standard sections, and file risks without promising a universal ATS pass.
Start with the text a parser can receive
An ATS-friendly resume is not a magic template. It is a file whose important facts remain available as text in a sensible order. CheckATS can show the text it extracts from a PDF, DOCX, or TXT file and flag a small set of structure and format signals. That observation belongs to this tool; it does not certify how an employer's system will parse the same file.
Download the synthetic plain-text fixture and run it through the checker. It uses a fictional person and employer. The fixture is intentionally simple so you can see the baseline before testing a resume you plan to submit.
A small, safe format baseline
Keep these facts easy to find in the extracted text:
- name and a usable contact block near the beginning;
- common headings such as Summary, Experience, Education, and Skills;
- employer, title, location when relevant, and dates for each role;
- bullets that describe work actually performed, with numbers only when you can support them.
These choices improve human review as well as the chance that a parser can identify fields. They are practical defaults, not a guarantee for a particular vendor.
Test the exported file, not just the editor view
After exporting, open the file and select the text. Copy it into a plain-text editor and check the reading order. Look for:
- a missing name, email, phone number, or LinkedIn URL;
- headings or dates that appear in the wrong sequence;
- characters replaced by boxes or unrelated symbols;
- a second page that is empty or contains only a footer;
- an image-only PDF with no selectable text.
Greenhouse documents an unsuccessful parse as a real failure mode in its own product. Its explanation is useful context, but it is not a specification for every ATS. Read Greenhouse's resume parsing guidance alongside your own extracted-text test.
What this checker can and cannot flag
The current v1 scorer can report extracted text, common section presence, contact signals, date and length signals, and a limited set of PDF parse risks. It can warn when a PDF contains little or no selectable text. A short TXT file is not labelled a scanned PDF, and the tool does not claim to inspect the visual geometry of columns, tables, icons, headers, or footers.
That distinction matters. If the text looks correct but the visual layout is complex, ask the employer for its format preference or choose a simpler layout. If the text is missing, fix the export first. Use the method and limits page for the exact boundaries.
A truthful keyword pass
Once the file is readable, paste the actual job description. Add a term only when the resume supports it. For example, if you used SQL, describe the work you did with SQL; do not add a tool because it appeared in the posting. A score change is useful when it follows a truthful edit, not when it rewards stuffing.
