## The short answer

CSVBox is a file importer that lets your users upload CSV, Excel, PDF, image and document files [^1]. Dromo is an import tool that maps imported columns to your schema using GPT, can be embedded in your site and can be hosted in your own cloud [^2] [^2]. RoloDexter maps contact field names onto 62 standard fields through four matching layers and ships as a Python or JavaScript package [^3] [^3].

For needs, CSVBox's pages cover imports up to 2M rows per import [^1]. Dromo's pages cover GPT based column mapping [^2], white labeling on every plan [^2] and self-hosting via Kubernetes [^2]. RoloDexter's claims cover mapping contact fields to a canonical schema with confidence scores [^3] [^3].

## What CSVBox, Dromo is built for

CSVBox's page says it supports imports of up to 2M rows per import [^1], and that it imports CSV, Excel (XLSX, XLS), PDFs, images and document files [^1]. CSV, TSV and Excel files up to 500 MB are handled by streaming [^1]. CSVBox's page says SOC 2 and GDPR compliance are included on every plan [^1], and that all data is encrypted in transit with TLS 1.2+ and at rest with AES-256 [^1]. A Model Context Protocol (MCP) server exposes importer-sheet management as tools AI clients can call [^1].

Dromo's page says it uses GPT to automatically map imported columns to your schema [^2], and that it is SOC 2 Type II certified [^2]. It can be deployed self-hosted via Kubernetes in your own cloud infrastructure [^2]. Its Headless product offers an API and SFTP support for a customizable import pipeline [^2]. Dromo says integration typically takes less than 30 minutes [^2].

## What RoloDexter is built for

RoloDexter is made by the team that publishes this site.

It maps contact field names onto a canonical schema of 62 fields through a four-layer pipeline of exact, normalized, fuzzy and heuristic matching, where the heuristic layer detects emails, phones, URLs and postal codes by data shape [^3]. Each field match records a confidence score and the strategy that produced it [^3]. It cleans matched values, for example phones to E.164, countries to ISO 3166-1 alpha-2, and unambiguous dates to ISO-8601 [^3].

You can resolve headers once and replay that plan on later runs with a JSON plan file [^3]. It can pull phone numbers out of free-text values such as notes [^3]. Large CSV or JSONL exports are processed in constant memory through lazy streaming [^3], and with the pandas extra installed it can rename and normalize a pandas DataFrame [^3]. An optional i18n generator calls Google Translate once, as a separate step you run yourself, to build cached language data for 40 languages [^3].

## Pricing and fees

CSVBox's free Sandbox tier is free forever at $0 a month [^4]. Paid plans start at $19 a month and scale with rows imported, with no per-seat fees [^1].

Dromo encourages new customers to experiment on its Free plan, then graduate to a usage-based plan that bills monthly and can be cancelled anytime [^2]. It recommends an unlimited plan at a flat annual rate once a customer is confident in the product [^2], and says it has no hidden fees or surprise upcharges such as for monthly billing or white labeling [^2]. Its Headless API is a premium add-on [^2]. The Dromo sources here do not state dollar amounts, so its prices are not published here [^2].

RoloDexter is free, with no paid tier [^3].

## Setting it up and daily use

Its Private Mode runs the importer entirely in the user's browser [^1]. Its MCP server exposes importer-sheet management as tools AI clients can call [^1].

Dromo is embedded in your site, and in Private Mode it operates entirely in the web browser [^2]. It can also be deployed self-hosted via Kubernetes in your own cloud infrastructure [^2], and its Headless product offers an API and SFTP support [^2]. Dromo says integration typically takes less than 30 minutes [^2].

RoloDexter is installed with pip or npm [^3], and the Python package needs Python 3.10 or newer [^3]. Core mapping runs locally without an API key [^3]. You run the map command to convert CSV and JSONL files with strict, override and dedupe options [^3], and a profile command reports the match rate, which fields were populated, which headers went unmapped and how many warnings there were, without writing mapped output [^3].

## Things to check before you choose

Check what file types you import. CSVBox's pages cover CSV, Excel, PDF, image and document files [^1], and RoloDexter's claims cover CSV and JSONL files [^3].

Check where the data runs. CSVBox's Private Mode runs entirely in the user's browser [^1], Dromo's Private Mode operates entirely in the web browser [^2], and RoloDexter runs core mapping locally without an API key [^3].

Check how the tool maps fields. Dromo's page says it uses GPT to map columns [^2], and RoloDexter's claims describe four-layer matching with confidence scores [^3] [^3].

Check the row limits that matter to you. CSVBox states caps up to 2 million rows per import [^1], and Dromo's sources here give none.

## How to choose

If you want your site's users to upload files, CSVBox's pages describe that [^1].

If you want an importer you can host in your own cloud, Dromo's page describes self-hosting via Kubernetes [^2].

If you want a tool that runs locally without an API key, RoloDexter's claims say that [^3].

If you want white labeling on every plan, Dromo's page says that is included at no extra cost [^2].

If you want contact field names mapped to a canonical schema with confidence scores, RoloDexter's claims describe that [^3] [^3].

If you want a tool that handles large imports, CSVBox's pages state up to 2M rows per import [^1].

If you want AI driven column mapping, Dromo's page says it uses GPT [^2].

If you want a free tool, CSVBox's free Sandbox tier [^4] and RoloDexter [^3] are both free.

## Frequently asked questions

### Can CSVBox, Dromo or RoloDexter work with AI tools?

CSVBox offers a Model Context Protocol (MCP) server that exposes importer-sheet management as tools AI clients can call [^1]. RoloDexter's claims do not describe an AI integration. For Dromo, its page says it uses GPT to automatically map imported columns to your schema [^2], but the facts here do not say it works with external AI assistants, so check its own pages for that.

RoloDexter is free; there is no paid tier. [^3] - [Visit RoloDexter](/go/start-rolodexter)
