The short answer
CSVBox takes uploaded files and can push validated rows to a webhook, Postgres, MySQL, Airtable, Google Sheets, Zapier, n8n and more than 20 other destinations [1]. OpenRefine is a free, open source tool for cleaning data and transforming it from one format into another [2]. RoloDexter matches contact column names to a fixed set of 62 standard fields [3].
On needs, CSVBox's page covers CSV, Excel, PDFs, images and document files [1] and a Sandbox plan at $0 per month [4]. OpenRefine's page covers drilling through large datasets on filtered views [2]. It also describes matching a dataset to outside databases [2]. RoloDexter's claims cover a free tool with no paid tier [3].
What CSVBox and OpenRefine do
CSVBox supports imports of up to 2M rows per import [1]. It supports CSV, Excel (XLSX, XLS), PDFs, images and document files [1]. Its page says CSV, TSV and Excel files up to 500 MB are read in parts so the page does not freeze while they load [1].
Its Private Mode runs the importer entirely in the user's browser [1]. Data is encrypted in transit with TLS 1.2+ and at rest with AES-256 [1]. It also offers a way for an AI client to manage importer setups as tools it can call [1].
OpenRefine is a free, open source tool for working with messy data [2]. It lets you drill through large datasets and work on filtered views of them [2]. It fixes inconsistencies by merging values it sees as similar using rules built into the tool [2], and it can match a dataset to outside databases [2]. You can rewind to any earlier state of the dataset [2], data is cleaned on your machine [2], and it can send cleaned data to Wikidata, the free knowledge base anyone can edit [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 [3].
It cleans matched values, for example phone numbers to a standard international format and countries to two-letter codes [3]. It can pull phone numbers out of free-text values such as notes [3].
A command line tool called rolodexter map converts CSV and JSONL files [3]. Large exports are processed in constant memory [3]. You can resolve headers once and replay that plan on later runs [3]. Core mapping runs locally without an API key [3].
Pricing and fees
CSVBox's free Sandbox tier includes 100 imports per month with up to 5 rows each [1]. The Sandbox plan is free forever at $0 per month [4]. Paid plans start at $19/month and scale with rows imported, with no per-seat fees [1]. Per-import row caps scale by plan, with 2 million rows on the Plus tier [1]. Its page says SOC 2 and GDPR, its security and data protection standards, are included on every plan [1].
OpenRefine is described as a free, open source tool [2]. No other price is given in its facts.
RoloDexter is free; there is no paid tier [3]. It is released under the MIT licence [3].
Setting it up and daily use
CSVBox's sources here give no install steps. They say it can push validated rows to destinations such as Postgres and Google Sheets [1] and that Private Mode keeps the importer in the user's browser [1].
OpenRefine's sources here give no install steps. Day to day, its page describes working on filtered views of data [2] and replaying your operation history on a new version of a dataset [2].
RoloDexter installs with pip or npm [3]. It needs Python 3.10 or newer [3]. Daily, a profile command reports how well your headers matched, without writing mapped output [3]. For Python users, pandas is a library for working with tables, and RoloDexter can rename and normalize one of those tables [3].
Things to check before you choose
Ask what the tool does with your file. CSVBox lists Private Mode [1], and OpenRefine says data is cleaned on your machine [2]. RoloDexter's core mapping runs locally without an API key [3].
Check file types and size. CSVBox lists CSV, Excel, PDFs and images [1]. Ask what OpenRefine and RoloDexter accept, since RoloDexter's claims name CSV and JSONL [3].
Check the language you work in. RoloDexter ships as a package on PyPI, the download site for Python packages, and on npm, the download site for JavaScript packages [3].
Check the optional language data step. It calls Google Translate once, as a separate step you run yourself [3].
Check whether you need a one-time cleanup or a repeatable run, and whether the tool fits your pipeline.
How to choose
If you want an importer that pushes validated rows to destinations such as Postgres, CSVBox's page describes that [1].
If you want to start on a Sandbox plan, CSVBox's page lists one that is free forever at $0 per month [4].
If you want to explore and clean messy data on filtered views, OpenRefine's page describes that [2].
If you want to match data to outside databases, OpenRefine's page describes that [2].
If you want contact CSV headers mapped to a fixed schema from a command line or Python, RoloDexter's claims describe that [3].
If you want a free tool with no paid tier, RoloDexter's claims say that [3].
