What OneSchema offers
OneSchema's AI agents are described as ingesting, normalizing and validating operational data from smart meters, billing platforms, asset management, SCADA, GIS and regulatory feeds. [1] Check whether the job is one mapping and cleaning step inside your own code, or an import flow your end users run. Then compare the options on where the data is processed, what each costs at your file volume, and whether you need a hosted upload screen.
Security and hosting are part of the OneSchema offer. Its hosting options are the part to check against your own rules for where data may be stored and processed. OneSchema offers US, EU, CA and AU region hosting, or self-hosted deployments on AWS, GCP and Azure. [1]
Cost is another reason to compare. OneSchema lists an Individual plan at $20 per month. [3] After the included credits are used, it charges $0.012 per credit. [3] Check what a credit covers for your own file volume before you compare.
RoloDexter: maps contact spreadsheet columns onto a fixed set of fields
RoloDexter is made by the team that publishes this site. It maps contact field names onto a standard schema of 62 fields through four steps: exact, normalized, fuzzy and heuristic matching. [2] The last step spots emails, phones, URLs and postal codes by the shape of the data. [2]
Each match records a confidence score and the strategy that produced it. [2] It also 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. [2] It can pull phone numbers out of free text such as notes. [2]
The `rolodexter map` command converts CSV and JSONL files and supports --strict, --override and --dedupe options. [2] The `rolodexter profile INPUT` command reports the match rate, populated fields, unmapped headers and warnings without writing output. [2] Large exports are processed in constant memory. [2] You can resolve headers once and replay that plan on later runs. [2]
RoloDexter is free, with no paid tier. [2] It is released under the MIT licence. [2] Core mapping runs locally without an API key. [2] You install it with pip or npm. [2] The Python package needs Python 3.10 or newer, and a JavaScript/TypeScript package is also available. [2] It ships as a Python package on PyPI and as a JavaScript/TypeScript package on npm. [2]
How to pick the right OneSchema alternative
Stay with OneSchema when region hosting or self-hosting on AWS, GCP or Azure matters. [1] OneSchema lists an Individual plan at $20 per month, with $0.012 per credit after the included credits. [3] [3] Check how those credits and plans map to your volume.
Choose RoloDexter when the job is mapping contact field names to a standard set of fields with a command line. [2] [2] The profile command reports match rate, populated fields, unmapped headers and warnings without writing mapped output. [2] Check whether 62 contact fields cover your data, since the schema is fixed. [2]
If you work in pandas, the pandas extra lets `map_dataframe` rename and normalize a DataFrame. [2] If you want repeatable runs, a saved header plan can be replayed later. [2] If cost is the question, RoloDexter is free. [2]
This page has facts for only these two tools. Before you decide, check whether you need a hosted upload screen for end users, which sources must be supported, and who must see the data.
