What it does
Add a production-ready import feature to your web app in just a few minutes. Your users can upload files, map columns, fix validation errors and submit data all in a few clicks. You receive ready-to-use data in your app.
Drop a production-ready CSV, Excel, and PDF importer into your SaaS in minutes. Handle up to 2 million rows per import, with column mapping, validation, webhooks, and clean data delivered to your API.
Drop in one widget. Users upload CSV, Excel, and PDFs — they map columns and fix bad rows in-browser. You receive clean, typed data at your webhook. SOC 2 + GDPR included on every plan. The CSV parser is 5% of the work. Mapping UX, locale dates, Excel quirks, 500 MB files, server-side validation — that's the other 95%, and it becomes a permanent maintenance tax. CSVbox replaces all of it. CSVBox drops a complete import experience into your app — file upload, column mapping, validation, and delivery — as a single embeddable widget. Production-ready imports in three steps — no SDK, no server-side scaffolding. Define schema, setup validation rules, transform functions and destination settings.…from csvbox.io

Talanoa▲343Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
