Question: How can I easily import data from CSV, XLS, and PDF files into my application without having to build it from scratch?

One good choice is Flatfile, a data import platform that handles many file formats. It's got features like AI-boosted column matching, onboarding collaboration and customizable workflows to make data import easier. It's geared for people who aren't programmers but comes with a library of APIs, SDKs and open-source plugins for programmers, so it should accommodate your needs and abilities.

Another option is Parsio, which uses AI and OCR technology to extract structured data from unstructured documents like PDFs and emails. Parsio can send data to destinations like Google Sheets and CRM systems, and it can integrate with tools like Slack and Cloud Storage. Its no-code interface and multilanguage support make it a good choice for automating data extraction and boosting productivity.

If you're looking for something more focused, Parseur is geared for AI-powered data extraction from PDFs, emails and spreadsheets. It can use template-based parsing and has an OCR engine for scanned documents. Parseur can integrate with automation tools and has a focus on data normalization, which could be useful for industries like finance and e-commerce where data consistency is important.
