Can ATS Read Resume Columns? How to Format Your Resume for ATS Success

Understanding ATS and How They Parse Resumes

ATS software acts like a gatekeeper for many companies, scanning resumes before a recruiter even looks at them. These systems don’t read resumes like humans do—they break down text line by line. But here’s the problem: they don’t always understand the structure of tables, columns, or graphic layouts. During parsing, ATS reads things in a linear order, so columns might get read as jumbled text, which can misplace important information or even omit it completely.

Modern ATS have improved. They parse resumes from DOCX or PDF files and try to preserve formatting, but some still struggle with complex layouts. If the system can't parse your data properly, it could miss keywords or job titles essential to you being found in a search. For those who want to test their resumes, tools like the ATS Resume Checker help identify how the system reads your document, showing if columns are causing problems.

Why Do People Use Columns in Resumes?

Columns might look attractive—they can make your resume appear organized and save space, enabling you to fit more information on fewer pages. For example, splitting skills into one column and experience into another visually separates your data. But keep in mind, what looks neat to a human eye often translates poorly to ATS.

One side of your resume could highlight certifications, the other employment history. Sounds good on paper. But ATS reading row by row will scrape across both columns in an order that doesn’t make sense. Dates may appear away from job descriptions, or contact info might be mixed with skills. This break in context can confuse the software, leading to inaccurate parsing.

How Do ATS Handle Columns? Technical Limitations

Behind the scenes, ATS parse resumes by breaking them down into plain text. Most ATS treat tables or columns as separate blocks or linear text without acknowledging spatial relationships. The system reads from left to right and top to bottom. Thus, columns in a resume stored within tables or text boxes tend to flatten into a row of words that lose logical grouping. This often results in a scrambled mess of candidate data.

For example, an ATS might read: “June 2026 – Present Project Manager XYZ Corp Skills: Excel, Communication…” rather than a clear, structured entry.

Even some ATS with parsing engines designed to pick up basic tables can’t guarantee comprehensiveness with more complex layouts or nested columns. So, while a few systems understand columns better than before, many will still misinterpret key fields—and that can literally be the difference between your resume getting noticed or being discarded.

Are All Columns Bad for ATS? When You Can and Can't Use Them

Though columns often cause parsing trouble, not every column is a death sentence for your resume. Simple, well-constructed columns that don’t rely on complicated table structures, nested grids, or text boxes might still work. For instance, a two-column layout with minimal styling where text is aligned neatly and consistently could survive ATS scanning.

But here’s the catch: if you use columns to separate critical information—like job titles from dates or skills from job descriptions—you risk losing the ATS’s ability to put things together accurately. If your resume uses columns just for aesthetics but holds no essential data split across them, you might be ok. Otherwise, columns often backfire.

Sometimes candidates use columns on resumes targeting human readers, after they’ve passed ATS screening. The goal is to make the format nice on second-round reviews. Even so, it’s generally safer to stick with single-column layouts for your main submission to avoid any parsing errors.

Common Problems Caused by Using Columns in ATS Resumes

Frankly, columns can jumble your timeline. Dates might detach from the roles they belong to, causing confusion about your career history. Skills could mix with unrelated job descriptions. Contact info may be displaced or missed entirely, which is catastrophic.

Another tricky issue: keywords. ATS search for specific terms to rank candidates. If columns mess up keyword placement or cause them to be read out of sequence, your resume could score low, reducing your chances of interviews. Headlines or section titles might get stripped or misread, further damaging clarity.

Best Practices: How to Make Your Resume ATS-Friendly Without Columns

Avoid tables and columns for main content if possible. Instead, use clear, separate sections—each with a bold heading—stacked vertically. Maintain a consistent flow for each job entry: job title, company, location, dates, followed by bullet points. That linear structure is what ATS is built to read best.

If you want to keep some visual interest, consider subtle line breaks or spacing, but avoid uneven alignment that could be interpreted as columns. Use standard fonts, avoid graphics or text boxes, and save your resume as a DOCX or ATS-friendly PDF if allowed.

Formatting dates and locations inline helps ATS associate them properly with your experience. Don’t cram extra contact details into columns that might be missed; place them in a simple header or footer.

Testing Your Resume for ATS Compatibility

Look, you don’t have to guess whether your columns hurt your chances. Use online ATS resume checkers, including the one offered at CV Owl's ATS Resume Checker. Upload your document and see how the parser reads it.

These reports highlight missed keywords, formatting issues, and how your data looks from an ATS perspective. When you see broken info or misplaced dates, that’s a strong sign your column structure needs revision. Iterating based on feedback is how you improve.

When Columns Might Work: Niche or Creative Fields

There are exceptions. Creative roles like graphic design or marketing might include columns on portfolios or resumes designed to be visually stimulating and stand out. If the ATS isn’t the main hurdle or if you submit your resume directly to a person, columns can enhance readability.

Still, always double-check if the job application requires or allows ATS parsing compatibility. For most corporate or recruiter-led screenings, simpler formats are safer. But when experimenting, keep an ATS-friendly version handy.

Summary: Should You Use Columns in Your Resume?

Columns offer the illusion of crisp organization but rarely help ATS. Since these systems read content sequentially, columns often create confusion instead of clarity. The best bet is a straightforward, single-column resume structured clearly with consistent headings and bullet points.

Got a resume with columns you want to use? Test it using an ATS checker first. Adjust accordingly after reviewing how your resume is parsed — that’s a recruiter-friendly move that could boost your chances.
