CSVBox and Nuvo both move spreadsheet files into software, but each takes a different path, so this page sets out what each does, what each costs and what to check before you pick one for CSV field mapping.

CSVBox is a tool that adds file import to software, reading CSV, Excel, PDFs, images and documents and sending validated rows on to places like Postgres, MySQL, Airtable or Google Sheets [1][1]. Nuvo, sold as Ingestro, describes AI-powered data imports and fully automated import flows that run on a schedule [2][2]. RoloDexter maps contact field names onto a canonical schema of 62 fields and normalizes the matched values [3][3].

For needs, CSVBox's page says it handles imports up to 2 million rows [1] and pushes validated rows to 20+ destinations [1]. Ingestro's page says its import flows are fully automated [2] and that it orchestrates more than 500K data workflows [2]. RoloDexter's claims cover local mapping of contact files with no API key [3].

The short answer

For a developer, CSVBox is a tool that adds file import to software, reading CSV, Excel, PDFs, images and documents and sending the validated rows on to places like Postgres, MySQL, Airtable or Google Sheets [1][1]. Nuvo, sold as Ingestro, describes AI-powered data imports and fully automated import flows that run on a schedule [2][2]. RoloDexter maps contact field names onto a canonical schema of 62 fields and normalizes the matched values [3][3].

On needs, CSVBox's page says it handles imports up to 2 million rows per import [1] and pushes validated rows to a webhook, Postgres, MySQL, Airtable, Google Sheets, Zapier, n8n and 20+ destinations [1]. Ingestro's page says its data import flows are fully automated [2], and that its agents build reusable workflows that run automatically on a schedule [2]. RoloDexter's claims say core mapping runs locally without an API key [3].

What CSVBox, Nuvo is built for

CSVBox's own page describes a tool that imports CSV, Excel, PDFs, images and document files [1]. It supports imports up to 2 million rows per import [1], with per-import row caps scaling by plan and 2 million rows on the Plus tier [1]. CSV, TSV and Excel files up to 500 MB are streamed [1]. Private Mode runs the importer entirely in the user's browser so file data never reaches CSVBox servers [1]. Data is encrypted in transit with TLS 1.2+ and at rest with AES-256 [1]. Validated rows can be pushed to a webhook, Postgres, MySQL, Airtable, Google Sheets, Zapier, n8n and 20+ destinations [1]. An MCP server exposes importer-sheet management as tools AI clients can call [1].

Nuvo, under the name Ingestro, describes AI-powered data imports [2] and fully automated import flows [2]. Its agents build reusable workflows that run automatically on a schedule for every file that follows [2]. Version 4.11.0 adds extraction of data from PDFs and XMLs, AI pre-processing and bring-your-own-LLM support [2]. It supports more than 50 languages for data mapping [5], is ISO 27001 certified and GDPR compliant [5] and offers self-hosting on your own infrastructure [5]. Ingestro says it orchestrates more than 500K data workflows [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 (exact, normalized, fuzzy, heuristic), 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, such as exact, normalized, fuzzy, heuristic or none [3]. It cleans matched values, for example phones to E.164, countries to ISO 3166-1 alpha-2, and unambiguous dates in birthday, created_at, updated_at and last_contacted to ISO-8601 [3]. The rolodexter 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]. The rolodexter map command converts CSV and JSONL files and supports --strict, --override and --dedupe options [3]. map_stream yields results lazily so large CSV or JSONL exports are processed in constant memory [3]. It can pull phone numbers out of free-text values such as notes [3]. Core mapping runs locally without an API key [3].

Pricing and fees

CSVBox's Sandbox plan is free forever at $0 per month [4]. CSVBox paid plans start at $19/month and scale with rows imported, with no per-seat fees [1]. Per-import row caps scale by plan.

Nuvo, sold as Ingestro, uses a monthly base rate based on the features you choose, plus a usage-based fee [5]. The Pro and Business plans each have a monthly base rate plus a usage-based component [5][5]. The Custom plan has a monthly base rate plus an annual contingent [5]. The facts here do not give dollar amounts for these plans, so their prices are not published here.

RoloDexter is free, and there is no paid tier [3]. It is released under the MIT licence [3].

Setting it up and daily use

CSVBox's page describes a browser-based importer, since Private Mode runs the importer entirely in the user's browser [1]. The facts here do not describe its install or setup steps, so check its own pages for those. Daily, the page says it streams CSV, TSV and Excel files up to 500 MB without frozen tabs [1], and pushes validated rows to 20+ destinations [1].

Nuvo's facts describe fully automated import flows [2] and agents that build reusable workflows running automatically on a schedule [2]. The Ingestro pages describe no install or setup steps in the facts here, so check its own pages for those.

RoloDexter is installed with pip or npm [3]. It ships as a Python package on PyPI and as a JavaScript/TypeScript package on npm [3]. The Python package is marked OS Independent and needs Python 3.10 or newer [3]. Core mapping runs locally without an API key [3]. With the pandas extra installed, RoloDexter can rename and normalize a pandas DataFrame [3]. You can resolve headers once and replay that saved mapping plan on later runs [3].

Things to check before you choose

Ask where your files will be processed. CSVBox's Private Mode runs the importer in the user's browser so data never reaches CSVBox servers [1], while Nuvo offers self-hosting on your own infrastructure [5]. Check where each will run your data.

Check what each handles as input. CSVBox reads CSV, Excel, PDFs, images and documents [1], and Ingestro adds extraction from PDFs and XMLs [2]. A reader should confirm which file types matter for the task.

Check the cost model. CSVBox's paid plans start at $19/month [1], while Ingestro uses a monthly base rate plus a usage-based fee [5]. Compare what each charges as volume grows.

Check compliance needs. Ingestro is ISO 27001 certified and GDPR compliant [5], and the facts here do not list compliance terms for CSVBox, so check its own pages.

How to choose

If you want a file import step that reads many formats and sends rows into your own systems, CSVBox's page describes that, reading CSV, Excel, PDFs, images and documents and pushing validated rows to more than 20 destinations [1][1].

If you want imports that run on their own and repeat, Ingestro describes AI-powered data imports [2] and fully automated import flows that run on a schedule [2].

If you want local, scriptable mapping of contact files that normalizes values, RoloDexter's claims describe that, running without an API key [3][3].

If you want a mapping plan you can replay on later files, RoloDexter's claims describe replaying a resolved header plan [3].

If you want a free option with no paid tier, RoloDexter's claims say it is free [3], and CSVBox has a free-forever Sandbox plan [4].
