How ATS Systems Read and Parse Your Resume

Understanding how applicant tracking systems extract and organize your resume information.

What ATS Systems Actually Do

When you submit your resume to a job application online, a machine reads it first:not a person. That machine is an applicant tracking system (ATS). It is not reading your resume as a document. It is extracting data from it.

Your resume's colors, fonts, design, and formatting are invisible to ATS. The machine only sees the text and its structure. It pulls out information, organizes it into fields, and stores those fields in a database.

Understanding what the machine is looking for:and in what order:explains why some resumes pass through easily and others get corrupted, scrambled, or rejected before a human ever sees them.

The Order ATS Systems Read Your Resume

ATS does not read top-to-bottom like a person would. It looks for standard sections and tries to match them to known fields.

What it searches for (in order):

  1. Header information : your name, phone, email, location (usually first or near the top)
  2. Professional summary or objective : a brief introduction (if present)
  3. Work experience : job titles, companies, dates, responsibilities
  4. Skills : a dedicated skills section
  5. Education : degree, school, graduation date
  6. Certifications and licenses : relevant credentials

If it cannot find these sections by looking for standard headings (like "Experience", "Skills", "Education"), it gets confused and may extract the wrong text into the wrong field.

How Text Extraction Works

When an ATS reads your resume, it converts it into plain text. This is the critical moment where design and formatting can cause problems.

Plain text extraction:

  • The system reads every character:letters, numbers, spaces, and line breaks:but nothing else
  • Colors disappear. Fonts disappear. Images disappear. Graphics disappear.
  • Only the text and its physical position on the page matter
  • Spacing and indentation are interpreted as structure

For example, if your resume uses a sidebar with columns, the ATS may read the left column, then jump to the right column, then back to the left:scrambling the order of all your information. If your contact information is in a header, it might get lost entirely.

Section Recognition

ATS systems look for section headings as anchors. If it sees "Experience", "Work History", or "Professional Experience", it knows the text below belongs in the work history field. If it does not recognize a heading, it gets lost.

Headings that work:

  • Experience, Work Experience, Professional Experience, Work History
  • Skills, Core Competencies, Key Skills, Technical Skills
  • Education, Academic Background, Degrees
  • Summary, Professional Summary, Objective
  • Certifications, Licenses, Credentials

Headings that confuse ATS:

  • Creative headings like "Where I've Worked" or "Things I Can Do"
  • Very abbreviated headings like "Exp" or "Ed"
  • No headings at all (just walls of text)
  • Headings hidden in graphics or images

What Breaks During Parsing

Several common resume design choices cause ATS systems to extract information incorrectly:

Layout issues:

  • Columns or sidebars : ATS reads left-to-right, top-to-bottom, scrambling columnar layouts
  • Text boxes : information in text boxes may be skipped or read out of order
  • Headers or footers : your name in the header gets lost; contact info in the footer may disappear
  • Tables : ATS struggles to read tables; it may extract cell by cell instead of row by row

Text formatting issues:

  • Graphics or icons : bullets replaced with icons, dividers, or decorative elements disappear
  • Unusual fonts : some fonts are harder for ATS to read; sans-serif fonts like Arial or Calibri work best
  • Inconsistent dates : "Jan 2020", "1/2020", and "January 2020" in the same resume confuse the parser
  • Special characters : bullets, dashes, or non-ASCII characters may disappear or be misread

How to Build for ATS Parsing

Now that you understand how ATS reads resumes, here is what works:

  • Single-column layout : all text flows top-to-bottom, left-to-right
  • Standard section headings : use recognizable names like "Experience", "Skills", "Education"
  • Consistent date formats : pick one format (like "January 2020") and use it everywhere
  • Simple text only : no graphics, icons, text boxes, or sidebars
  • Clear spacing : use line breaks to separate sections, not tables or boxes
  • Standard fonts : Arial, Calibri, or Times New Roman read cleanly
  • Contact info in the header : name at the top, then phone and email on the next line

Testing Your Resume's Parsing

Want to see what an ATS actually extracts from your resume? Upload it to the free ATS checker and you will see exactly what the machine reads:sections, extracted dates, skills, everything. If you see text in the wrong place or missing information, you know your resume has a parsing problem that needs fixing.

The ATS checker shows you the raw extraction. If it looks scrambled or incomplete, your resume needs restructuring before you apply.

Build the Right Structure First

Understanding ATS parsing means you can design a resume that works for both machines and people. The best approach: build for the machine first (structure, standard headings, single column), then write great content that also impresses humans.

The ATS Resume Builder handles the parsing structure for you:single-column layout, standard headings, consistent formatting:so you can focus on writing strong content without worrying whether the machine will read it correctly.

Common Questions

Q: Can ATS read PDFs?

Yes, but PDFs extract messier than Word files. Formatting in PDFs is often harder for ATS to parse cleanly. When you have a choice, Word (.docx) is safer.

Q: What if my resume is a graphic or image?

ATS cannot read images. If your resume is a picture file (JPG, PNG), the ATS cannot extract any text at all. Always submit a text-based file (Word or PDF).

Q: Does ATS read keywords?

Yes. Many ATS systems search for specific keywords related to the job. If the job posting mentions "Python" and your resume says "Python", the system finds the match. This is why it matters to include relevant skills and keywords your target jobs actually use.

Q: Can I use a fancy font?

Fancy or unusual fonts can be harder for ATS to read cleanly. Stick with standard fonts like Arial, Calibri, or Times New Roman so the extraction is accurate.
