How to Fix Formatting Issues That Break ATS Parsing

If you’ve ever uploaded a polished resume only to hear silence from recruiters, the culprit is often hidden in the document’s layout. ATS (Applicant Tracking System) parsing relies on clean, machine‑readable formatting; a stray table, odd bullet, or unconventional font can cause the system to discard your application before a human ever sees it. In this guide we’ll break down the most common formatting pitfalls, give you a step‑by‑step cleanup checklist, and show you how to use Resumly’s free tools to verify that your resume is ATS‑friendly.

Why ATS Parsing Matters

Modern hiring pipelines filter thousands of applications through an ATS before they reach a hiring manager. The ATS extracts key data—name, contact info, work experience, skills—and matches it against the job description. When the parser encounters non‑standard formatting, it may:

• Skip entire sections (e.g., “Work Experience” disappears)
• Misinterpret dates, turning “Jan‑2020 – Present” into nonsense
• Drop critical keywords, lowering your relevance score

According to a Jobscan study, 75% of resumes are rejected by ATS before a recruiter reviews them. Fixing formatting issues is therefore the fastest way to improve your chances of landing an interview.

Step‑By‑Step Guide to Clean Up Your Resume

Below is a 15‑step checklist you can follow in any word processor (Microsoft Word, Google Docs, or the Resumly AI Resume Builder). Tick each item as you go.

1. Open the original file in the editor you used to create it.
2. Remove all tables – copy the text into a plain paragraph and re‑format with headings.
3. Delete headers and footers – place your name, phone, email, and LinkedIn URL at the very top of the document.
4. Eliminate text boxes, shapes, and SmartArt – convert any content inside them to regular text.
5. Switch to a single column – ensure there are no column breaks.
6. Replace fancy bullets with simple hyphens (-) or asterisks (*).
7. Standardize fonts – set the entire document to Arial 11 pt or Calibri 11 pt.
8. Remove all images (including logos) unless the job posting explicitly asks for a portfolio link.
9. Check line spacing – use 1.0 or 1.15 spacing; avoid extra spacing before/after paragraphs.
10. Use standard date formats (e.g., “Jan 2020 – Present”).
11. Add clear section headings (e.g., “Professional Experience”, “Education”).
12. Save as .docx first, then export to PDF using the Save As > PDF (Word‑compatible) option.
13. Run a spell‑check – ATS may drop misspelled keywords.
14. Run Resumly’s ATS Resume Checker – https://www.resumly.ai/ats-resume-checker – fix any flagged issues.
15. Run the Resume Readability Test – https://www.resumly.ai/resume-readability-test – aim for a score of 70+.

Mini‑Conclusion: Fixing Formatting Issues That Break ATS Parsing

Every stray table, hidden header, or exotic font is a roadblock that can break ATS parsing. By following the checklist, adhering to the do’s and don’ts, and leveraging Resumly’s free testing suite, you turn a risky resume into a high‑visibility, machine‑readable document.

Frequently Asked Questions

1. Does the ATS read PDFs the same way it reads DOCX files? Most modern ATS can parse PDFs, but only if the PDF is generated from a Word document (not scanned). For maximum compatibility, upload a DOCX when the job portal allows it.

2. Can I keep a subtle color scheme for headings? Yes, as long as the text remains black on a white background when the file is saved as PDF. Some parsers strip color, so the visual effect may disappear for the ATS.

3. Are bullet symbols like “✔” or “★” safe? No. Stick to hyphens (-) or standard circles (•). Uncommon symbols are often dropped, causing the parser to merge lines.

4. How many keywords should I include? Aim for 5‑7 core keywords that appear in the job description. Over‑stuffing can look spammy and may be penalized by the ATS.

5. Will removing all formatting make my resume look bland?\nNot at all. A clean, single‑column layout with clear headings looks professional and is preferred by both ATS and hiring managers.

6. Should I use a resume template from the internet? Only if the template is ATS‑optimized. Many free templates include tables and graphics that break parsing. The Resumly AI Resume Builder provides templates that are already vetted.

7. How often should I re‑run the ATS checker? Every time you make a substantive edit—add a new role, change a bullet, or adjust the layout.
