Updog and react-csv-importer at a glance

DimensionUpdogreact-csv-importer
Data privacyFiles are parsed, validated, and edited in the browser. Row data never reaches Updog's servers, so there is no data processor, DPA, or residency to manage.An open-source (MIT) React library that runs entirely in the browser; the file reader runs in-browser, so raw CSV data never has to reach a backend. As a self-hosted library there is no vendor, so compliance certifications, a DPA, and data residency do not apply.
White-labelFull styling through CSS variables and class overrides. No Updog logos or "powered by" on any plan, including the free one.Ships a standalone CSS stylesheet you can override with your own rules. As an MIT library it carries no vendor branding.
PricingFree for development, and a 14-day trial with no card when you go live. In production, a flat $19 per domain per month, the same at any volume, and your first paid domain includes a free one for staging.Free and open-source under the MIT license. No paid tiers or usage fees.
Data mappingSchema in code. Fuzzy column matching with a built-in synonym dictionary you can extend, or connect the AI your organization already approves through a hook, so it runs on infrastructure you control with no new AI vendor to clear. Updog keeps no mapping history. Your app owns that state and can supply saved selections on later imports. Maps incoming values to your options. Auto-detects number and date formats. Combines files by upserting on a key.Fields defined in code as component children. Columns auto-match when file headers match field labels, with a drag-and-drop step to remap. A data-handler callback receives the parsed rows. No value mapping, format detection, multi-file import, or AI found.
Data cleaningCells edit inline through a typed editor per column, text, number, date, select, or multi-select, with clipboard, fill handle, and full undo and redo. Values pass a transform on the way in, then validation runs at three levels, built-in rules, your own checks, and asynchronous ones. Sorting, full-text search, filters on the columns you enable, and formulas. Invalid rows can block submit or come through flagged. Any view also exports in any supported format.Validation and error handling run in your own data-handler callback rather than a built-in rules system. No inline cell editing, find & replace, bulk transforms, or undo/redo; it is an import-and-map widget, not a spreadsheet editor.
Scale & performanceAbout one million rows at around 20 columns in the browser, with a filter on every column. No fixed row cap, the browser tab's memory is the ceiling, and fewer columns reach further. Filtering and sorting run in a worker, measured at 30 to 250 milliseconds over a million rows.Client-side, built on Papa Parse with true streaming and configurable chunking, handling 1GB+ files. No fixed row limit documented.
IntegrationReact component, plus a Web Component for Vue, Angular, Svelte, and vanilla JS. Renders inline in your page's DOM. Imports CSV, TSV, Excel, JSON, and XML, plus any other format through a parser you register yourself.A React component (React 16.8+), rendered inline in your page, with TypeScript support. No Vue, Angular, or vanilla-JS build found.
Languages & RTLEnglish by default, with every interface string overridable, so you can localize into any language. Right-to-left is first-class. It flips layout, text alignment, scrollbars, and column pinning, and carries through to export.Six built-in interface locales, English, Danish, German, Italian, Brazilian Portuguese, and Turkish, plus a custom-locale interface. No Arabic or Hebrew locale, and no right-to-left support was found.
AccessibilityAn ARIA grid with full keyboard navigation and screen-reader support. WCAG 2.2 AA is the level Updog builds to, with automated rule checks over every component and every step of the importer on each test run. Updog holds no independent audit or VPAT.The README states screen-reader and keyboard accessibility, without a cited WCAG level. Its test suite checks the labels and the focus announcements that back the claim, and the repository has been archived since January 2024.
