In 2013, she was inducted into the National Junior Honor Society. She has expressed interest in transitioning from acting to a career in law someday. Her childhood dream was to be elected President of the United States; and her remarks led to her being invited to view the New York State Assembly and New York State Senate debate in person. She was acknowledged by Assemblyman Francisco Moya on the floor of the Assembly and recognized for her contributions to the arts. In addition to being fluent in English and Spanish, Ptacek has been studying Mandarin Chinese since childhood. In 2018 she started attending Stanford University.

As a child actress, Ptacek appeared in more than 70 television commercials, and on the covers of numerous national magazines. She was also one of the few child models who has had the privilege of walking the runway at Bryant Park during the annual Fall Fashion Week in New York City. Discovered by Wilhelmina Models, then represented by New York's Abrams Artists Agency during her child acting and modeling career, the critical acclaim she received for her role in the Oscar-winning film Curfew led to efforts by the "Big Four" talent agencies - Creative Artist Agency (CAA), United Talent Agency (UTA), William Morris Endeavor (WME), and International Creative Management (ICM) - to recruit her, and ultimately, she chose to work with ICM. Ptacek was one of the highest-paid child models in the world, earning approximately $250,000 annually as of 2010, when she had appeared as the "face of" Ralph Lauren, and worked in major campaigns for high end designers like Bonnie Young, Miss Sixty, Monna Lisa, and Siviglia, and fashion houses like Guess, The Gap, H&M, and Benetton. One of her most notable campaigns was for Macy's in 2009, when she revived Natalie Wood's childhood role of "Virginia" in Macy's Yes, Virginia, There is a Santa Claus -themed campaign for the holiday season, which saw Ptacek's appearance in a series of full page advertisements in each of New York's major newspapers, TV commercials with celebrities, such as Donald Trump, Queen Latifah, Martha Stewart, and Carlos Ponce, and public appearances on behalf of Macy's that sought to raise support for the literacy organization, Reading is Fundamental (RIF). She also appeared on the cover of Newsweek.

In 2009, she was cast in the comedy film The Rebound with Catherine Zeta-Jones. After landing small roles in several other films, she was cast in lead roles in several feature films released in 2013 and 2014, including A Little Game, Anything's Possible, Tio Papi, and A Miracle in Spanish Harlem. Ptacek has appeared in television shows including Saturday Night Live, A Gifted Man, Royal Pains, The Beautiful Life, Body of Proof, and appeared with First Lady Michelle Obama on Sesame Street.

Ptacek was given a three-year contract as Dora in Dora the Explorer, in November 2010, with the first new TV episodes with her voice in January 2012. She replaces previous voices Kathleen Herles and Caitlin Sanchez. She notes she was a fan of the character before being cast, amongst 200 girls auditioning. The role earned her a "Best Young Actress - Television" at the 2012 Imagen Awards, which she attended. She is nominated in the 2014 awards for "Outstanding Performance in a Children's TV Series". Specials voiced by Ptacek include Dora Rocks!, Dora's Rescue in Mermaid Kingdom, Dora's Butterfly Ball, Dora's Royal Rescue, Dora's Easter Adventure, and Dora's Fantastic Gymnastics Adventure (2012).

Ptacek starred in the Shawn Christensen short film Curfew (2012) as well as its feature film version Before I Disappear (2014), about a depressed man asked to take care of his niece. Christensen had auditioned a handful of actresses for the role, but saw Ptacek on a morning show appearance. He admits that he hoped she would nail the audition, and describes her as "phenomenal". Receiving extensive critical acclaim, Ptacek's performance was deemed "a breakthrough", "memorable", "charming", an "eerie, mature confidence for someone so young", and "delightfully annoying". The film was nominated for "Best Live Action Short Film" at the 85th Academy Awards, the first time the category was open to all members of the Academy of Motion Picture Arts and Sciences voting. The film won, with Ptacek in attendance. She attended the Vanity Fair Oscar party with Christensen. Ptacek has personally won Best Young Actress at the 2012 Sapporo Short Fest (the film screening there the year after with an appearance by Ptacek), A feature film of the story has been announced, with Ptacek announced to return. Best Actress at the 2013 Rincon International Film Festival, and Best Actress at the 2013 Vaughan Film Festival.

Joey Dedio, screenwriter and top star of the film Tio Papi, in which Ptacek stars, commented in an interview that "we hit the jackpot with that one. She’s a class act, as are her parents." Ptacek was nominated for a "Best Actress/Supporting Actress - Feature Film" Imagen Award, alongside nominees including Elizabeth Rodriguez from the same film; Míriam Colón (Bless Me, Ultima) won the category.

Dora and Friends: Into the City (2014–2017), also has Ptacek as the voice of Dora. While Ptacek speaks in a higher pitch for Dora the Explorer, the new series allows her a more natural voice, as the character is 10 to Ptacek's real life age at the start of production, 12. Production continues on the original series. Producers have allowed Ptacek to modify lines, when she feels she can provide a more accurate version of how youth speak. Ptacek won "Outstanding Performance in a Youth/Children’s TV Series" at the 2015 NAACP Image Awards.

Fátima volunteers as a "Celebrity Ambassador" for the Elizabeth Glaser Pediatric AIDS Foundation, and has done work for the Make-A-Wish Foundation in conjunction with the Macy's Believe Campaign, and the Morgan Stanley Children's Hospital.
