CSVBox and OneSchema compared on what each does for CSV imports and field mapping, what each costs, and what to check before you pick one for your app's data importing.
CSVBox handles the file upload and import step of an app, reading CSV, Excel, PDFs, images and document files and pushing validated rows onward [1] [1]. OneSchema ingests files from SFTP, API, S3, email or native API connectors for enterprise systems of record [2]. RoloDexter maps contact field names in a CSV or JSONL file onto a canonical schema of 62 fields and records how confident each match is [3] [3].
On needs, CSVBox's page says imports can reach up to 2M rows per import [1], and that compliance such as SOC 2 and GDPR is on every plan [1]. OneSchema's page says it puts AI agents to work on messy enterprise files larger than 10GB [2] and offers region hosting or self-hosted deployments [2]. RoloDexter's claims say core mapping runs locally without an API key, and its report shows match rate, mapped fields, unmapped headers and warnings [3] [3].

The short answer
CSVBox handles the file upload and import step of an app, reading CSV, Excel, PDFs, images and document files and letting you push validated rows onward [1] [1]. OneSchema ingests files from SFTP, API, S3, email or native API connectors for enterprise systems of record [2]. RoloDexter maps contact field names in a CSV or JSONL file onto a canonical schema of 62 fields and records how confident each match is [3] [3].
On needs, CSVBox's page says imports can reach up to 2M rows per import [1], and that compliance such as SOC 2 and GDPR is on every plan [1]. OneSchema's page says it puts AI agents to work on messy enterprise files larger than 10GB [2], and offers region hosting or self-hosted deployments on AWS, GCP and Azure [2]. RoloDexter's claims say core mapping runs locally without an API key, and its report shows match rate, mapped fields, unmapped headers and warnings [3] [3].
What CSVBox, OneSchema is built for
CSVBox's own page says it supports imports of up to 2M rows per import [1]. It reads CSV, Excel, PDFs, images and document files [1], and CSV, TSV and Excel files up to 500 MB, streamed [1]. It can push validated rows to a webhook, Postgres, MySQL, Airtable, Google Sheets, Zapier, n8n and more than 20 other destinations [1]. Compliance, SOC 2 and GDPR, is on every plan [1], and data is encrypted in transit with TLS 1.2+ and at rest with AES-256 [1]. A Private Mode runs the importer entirely in the user's browser so file data never reaches CSVBox servers [1]. An MCP server exposes importer-sheet management as tools your AI client can call directly [1].
OneSchema's own page says it can ingest files from SFTP, API, S3, email or native API connectors to enterprise systems of record [2], and can put AI agents to work on messy enterprise files larger than 10GB [2]. It is SOC 2 Type 2, SOC 3, GDPR, CCPA and HIPAA compliant with data stored in US data centers [2], offers US, EU, CA and AU region hosting or self-hosted deployments on AWS, GCP and Azure [2], and uses fine grained access controls so only authorized users can view schemas and import data [2]. Its data retention policy defaults to 7 days and can be deleted via API [2], and data at rest is encrypted with AES-256 while TLS v1.2 is used in transit [2].
What RoloDexter is built for
RoloDexter is made by the team that publishes this site.
It maps contact field names in a CSV or JSONL file 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, whether exact, normalized, fuzzy, heuristic or none [3]. Matched values are cleaned, 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 map command converts CSV and JSONL files and supports strict, override and dedupe options [3]. 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]. Headers can be resolved once and that plan replayed on later runs through a saved schema or a JSON plan file [3]. It can pull phone numbers out of free text such as notes [3]. Large files are processed in constant memory because results come out lazily [3].
Pricing and fees
CSVBox's free Sandbox tier includes 100 imports per month with up to 5 rows each [1], and 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]. The Plus tier allows 2 million rows per import [1]. The facts here state no dollar price beyond the Sandbox and the $19/month start, so a full plan price list is not published here [1].
OneSchema's Individual plan costs $20 per month [5]. After 4,000 free credits are used, it charges $0.012 per credit [5]. Its sources here give no dollar price for higher plans, so those are not published here [5].
RoloDexter is free, and there is no paid tier [3]. It is released under the MIT licence [3]. No other RoloDexter price is stated in its claims.
Setting it up and daily use
The CSVBox facts here do not describe its installation. Its daily use is the importer the end user sees: it can run entirely in the user's browser in Private Mode so file data never reaches CSVBox servers [1], and validated rows can be pushed to destinations such as a webhook, Postgres, MySQL, Airtable, Google Sheets, Zapier, n8n and more than 20 others [1]. An MCP server lets an AI client call importer-sheet management tools [1].
The OneSchema facts here do not describe its installation either. Its daily use covers ingesting files from SFTP, API, S3, email or native API connectors [2], with fine grained access controls that limit who can view schemas and import data [2]. Its sources here say nothing more about routine use.
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]. Daily, the map command converts files, the profile command reports match rate before anything is written, and mapped output can normalize values such as phones, countries and dates [3] [3] [3].
Things to check before you choose
Ask how your files arrive. CSVBox's page speaks of an importer in the browser, with file data kept off its servers in Private Mode [1], while OneSchema's page speaks of ingesting from SFTP, API, S3, email or native connectors [2]. RoloDexter's claims speak of CSV and JSONL files mapped locally [3] [3].
Check how your data is protected and where it must stay. CSVBox states SOC 2, GDPR, TLS 1.2+ and AES-256 [1] [1], and OneSchema states SOC 2 Type 2, SOC 3, GDPR, CCPA, HIPAA and hosting regions [2] [2]. Check RoloDexter's own pages for its compliance position, since its claims here do not cover it.
Check your environment. RoloDexter needs Python 3.10 or newer for its Python package [3]. Check what each source says about file limits, per-unit fees and row caps before you commit.
How to choose
If you run an app where end users upload files and you want validated rows sent on to other systems, CSVBox's page describes an importer that reads several file types and pushes rows to many destinations [1] [1].
If you handle enterprise files from SFTP, API, S3 or email, with large messy files and region or self-hosted deployment, OneSchema's page describes that [2] [2] [2].
If you map contact fields from CSV or JSONL files onto a known schema yourself, with a confidence score for each match and a report of what stayed unmapped, RoloDexter's claims describe that [3] [3] [3].
If you want the mapping to run on your own machine without an API key, RoloDexter's claims say core mapping is local [3]. If budget is the deciding factor, CSVBox has a free Sandbox tier [1], OneSchema gives 4,000 free credits [5], and RoloDexter is free [3].
