Commabot
Commabot is a conversational CSV workspace: upload a spreadsheet, then chat to clean, transform and chart it without writing a single formula. It also ships ready-made workflows that prepare contact lists for CRM import.
What is Commabot?
Commabot is a web application that turns a CSV file into a conversation. You upload a spreadsheet, then ask for what you want in ordinary language — a question about the numbers, a chart, a tidied-up column — and the assistant does the work. The homepage sums the promise up as transforming and analysing your data with conversation, and insists on what you do not need: no formulas, no complex tools. A single button, Work on my CSV, leads straight to the chat.
The product has two faces. The first is that open-ended editor: ask questions in plain language, generate charts and summaries, clean and transform columns, then keep or discard the result. After each transformation the app asks whether the output matched your expectations and offers to delete the table outright. The kinds of files named on the site are sales reports, survey data and financial records.
The second face is a library of ready-made workflows aimed squarely at contact lists. Six are named: formatting phone numbers to the international E.164 standard, removing duplicates, removing unsubscribed contacts, preparing a file for a HubSpot import, doing the same for Salesforce, and merging several lists into one dataset. Each displays how many times it has been used and its average processing time, and runs from a single click. A free-text field lets you add requirements — which columns to keep, a filtering rule, an output format — without rewriting the workflow itself. Creating new workflows is reserved for administrators.
The boundaries are as clear as the promise. Commabot handles one CSV file at a time and no other format. It is a web application only: no mobile app, no public API, no developer documentation. Signing in goes through a Google account. Charts are rendered with Chart.js and the backend runs on Google Cloud, with a header indicator linking to a public status page. The site itself is a single-page application whose served HTML carries no text at all.

When to use Commabot / When not to
A quick filter to help you decide if Commabot is the right fit.
When to use Commabot
- Sales and marketing teams who lose hours deduplicating prospect lists before a CRM import
- Recruiters and talent sourcers tidying candidate databases exported as CSV
- Analysts and operations staff who want a quick chart or summary without opening a BI tool
- Solo founders and freelancers with no data engineer on hand to write a cleaning script
- Event organisers merging attendee lists collected from several sources
When not to use Commabot
- Teams working with Excel workbooks, JSON or live database connections, since only CSV is supported
- Anyone needing to process several files at once: the uploader takes one file at a time
- Organisations handling regulated or sensitive data, as the site publishes no GDPR, SOC 2, ISO or HIPAA commitment
- Developers looking for an API or an automated pipeline, neither of which is offered
- Mobile-first users, because the tool exists only as a web application
How to use Commabot
A typical end-to-end flow, from setup to results.
- Open commabot.com and click Work on my CSV, which opens the chat workspace
- Sign in with a Google account: without it, the app asks you to sign in before showing any file
- Upload a CSV by dragging it onto the drop zone or picking it from your computer, one file at a time
- Let the assistant greet you with its invitation to upload a file and start analysing
- Ask your first question in plain language, or request a chart, a summary or a cleanup
- Review the table the assistant produces and answer the confirmation prompt to keep or delete it
- Rename or describe the table through the table details panel if you want to find it again
- For contact lists, go to the workflows section and pick a ready-made workflow instead
- Add any specific requirements in the free-text field, then launch the workflow
- Save the tables and conversations you want to keep, since nothing is retained otherwise

Pricing & Plans
Commabot is free to use at the time of this review: uploading a file and working with it costs nothing and requires no payment card. A single paid tier, Extended Access, is announced at USD 17.00 per month, currently advertised at USD 9.00 per month to anyone who joins the waiting list. It cannot be purchased yet, the button joining a list rather than opening a checkout.
- conversational CSV editing and the workflow library at no cost
- with usage limits that are not quantified
- USD 17.00 per month
- advertised at USD 9.00 per month for waiting-list members
- adding higher CSV processing and analysis limits
- early access to new features and export of results in several formats. Announced but not launched.
Data, GDPR & hosting
A consolidated view of how Commabot handles your data.
GDPR overview
There is no mention of the GDPR anywhere on the Commabot site. The word never appears, and neither does CCPA, a data processing agreement, an Article 27 EU representative, a data protection officer or a subprocessor list. The privacy policy, dated 1 June 2025, nevertheless grants rights that resemble the European ones: access, correction, deletion of the account and its data, export of saved conversations, and opting out of non-essential communications. The children's clause sets the floor at 13, the American COPPA threshold rather than a European one. Data is said to sit on Google Cloud Platform, with no country named. For a European user the practical conclusion is that the tool offers no contractual GDPR guarantee: what it describes are unilateral promises, not a compliance framework.
Who owns the data?
Commabot's privacy policy states that it does not sell, trade or otherwise transfer personal information or uploaded CSV data to third parties. Three exceptions are listed: a legal requirement or legal process, the protection of its own rights, property or safety, and service providers who help operate the platform under confidentiality agreements. Those providers are never named. The terms contain no licence clause over uploaded content, so nothing indicates the publisher claims any right on your files. The About page goes further, saying contact data is neither read, sold nor used to train models, and that it does not leave your workspace without explicit permission.
Reuse rights
Nothing in the terms restricts what you do with the files you upload or with the results Commabot returns: no licence, attribution or resale clause applies to them, and the privacy policy lets you export saved conversations and delete everything at any time. The obligation runs the other way. The acceptable-use section forbids processing data you do not have the right to analyse, which places the burden of lawfulness squarely on you, and that matters when the files are contact lists holding other people's personal data. One caveat on reuse: the service is supplied as is, with no warranty on the accuracy of its analyses, so results deserve a check before they feed a decision.
Data retention & training
Hosting summary
The privacy policy states that data is stored on secure Google Cloud Platform infrastructure, and the About page repeats that contact lists are processed using Google Cloud. That is as far as the site goes: no hosting country and no region are declared anywhere, and no jurisdiction is named for disputes or data transfers. Uploaded CSV files are described as processed in memory and deleted automatically after the session unless explicitly saved; saved conversations are said to be encrypted and stored securely, under industry-standard security measures that are not detailed further. The web server resolves to an anycast address geolocated in the United States, and the registrar is American, but neither of those is a hosting commitment from the publisher. In practice a European user has no published guarantee about where the data physically sits, nor any transfer mechanism to point to.
Things to keep in mind
Risks and trade-offs to weigh before adopting Commabot.
- You are uploading other people's personal data: the terms forbid processing data you have no right to analyse, and that responsibility stays with you
- No legal entity, address or country is disclosed, so there is no identifiable counterparty if something goes wrong
- No GDPR framework, no data processing agreement and no named subprocessors, which is hard to reconcile with contact lists from EU residents
- Session-replay and analytics trackers record how you use the app without being named in the privacy policy
- The terms disclaim any warranty on the accuracy of analyses, so trusting a generated summary without checking it is a real risk
- Aggregated usage analytics may be kept indefinitely, unlike the files themselves
- Letting a conversational tool reshape a list can quietly erode the habit of inspecting data, and a silently dropped or merged row is easy to miss
Setup & Integrations
Technical difficulty
Very low. There is nothing to install and nothing to configure: Commabot is a web application, the only prerequisite is a Google account, and the first useful action is dragging a CSV onto the page. No API key, no connector and no data mapping are involved, and customising a workflow means typing a sentence into a text field. The one restriction is that creating new workflows from scratch is reserved for administrators, so an ordinary user works with the existing library.

Should you pick Commabot?
Commabot does one thing and says so plainly: it lets someone who does not write formulas get useful work out of a CSV file by talking to it. That focus is its main strength. The interface offers a single button, the workflow library names six concrete jobs anyone who has prepared a contact list will recognise, and the confirmation step after each transformation is a genuinely good idea, since the tool asks you to approve the table it produced instead of assuming it got things right. Today the service is free and needs no card, which makes trying it a matter of minutes.
The reservations are not about the product but about the publisher. No legal entity is identifiable anywhere: no company registration, no postal address, no country, nothing beyond a lowercase copyright line. The GDPR is never mentioned, there is no data processing agreement, no EU representative and no list of the service providers the privacy policy alludes to. Analytics and session-replay trackers load on the page without appearing in that policy. For a tool whose core use case is uploading other people's names, phone numbers and email addresses, that gap weighs more than it would elsewhere, and the terms make the lawfulness of those uploads your responsibility.
The commercial picture is unsettled too: the only paid tier is a waiting list, so the announced price may still move before anyone can pay it. Taken for what it is — a young, deliberately narrow, free utility from an anonymous publisher — Commabot is a sensible choice for one-off cleaning of a list you could afford to lose, and a poor one for regulated, sensitive or contractually constrained data.
