How to Enrich a CSV with B2B Person, Company, and IP Data

At People Data Labs, many of our customers access data through APIs and flat files, especially when they are building recurring workflows or running data at enterprise scale. But not every enrichment need starts with a technical integration.

Sometimes, you just have a CSV and need better data back.

That is exactly what our Batch Enrich tool is for. It gives self-serve users a simple way to upload a CSV, enrich it with B2B person, company, or IP data, review coverage, purchase matched records, and download the results.

If you are working on a one-off enrichment project, testing a new use case, or looking for a quick way to enrich a list without building an integration first, Batch Enrich can be a practical place to start.

B2B CSV enrichment is the process of adding business data to records in a spreadsheet.

Depending on the file, you might enrich:

For example, you might start with a CSV that includes names and email addresses. After enrichment, that same file could include job titles, seniority, departments, employers, company domains, and LinkedIn profiles.

Or you might start with a list of company domains. After enrichment, you could add company size, industry, revenue, location, funding data, and other firmographic fields.

Or you might upload a list of IP addresses and enrich them with company-level data so your team can better understand which businesses may be visiting your website or engaging with your digital properties.

In other words, CSV enrichment helps you move from “we have a list” to “we have a list we can actually use.”

A CSV is often where B2B data work begins.

Sales teams export lead lists. Marketing teams pull event registrants. RevOps teams work with CRM exports. Growth teams build target account lists. Website and demand gen teams analyze traffic data. Founders and operators often use spreadsheets to test new markets, campaigns, and workflows.

The challenge is that those files are often just the starting point.

A lead list may include names and emails, but not enough context to prioritize outreach.

An event registration list may include company names, but not enough firmographic data to segment follow-up.

A CRM export may be missing titles, seniority, company size, industry, or location fields.

A target account list may include domains, but not enough company data to understand fit.

An IP export may show activity, but not the companies behind that activity.

CSV enrichment helps close that gap by adding relevant B2B data to the records you already have.

Lead list enrichment is one of the most common reasons people look for a CSV enrichment tool.

You may have a list of prospects from an event, outbound campaign, CRM export, data pull, or manual research project. But the file may be missing the context needed to decide who to prioritize and how to reach out.

By enriching the file with person and company data, you can better understand:

This can help sales and growth teams turn a basic prospect list into an actionable list for outreach.

Account lists often start with company names or domains.

That may be enough to identify the company, but not enough to evaluate fit. You may still need industry, employee count, revenue, location, funding, or other firmographic attributes.

Company enrichment can help turn a simple account list into a more useful planning file for segmentation, territory design, account scoring, campaign targeting, or market analysis.

Event and webinar registration data is often limited.

A form may capture name, email, and company, but not much else. That makes it harder to prioritize attendees, identify high-fit accounts, or personalize follow-up.

Enriching a registrant CSV with person and company data can help marketing and sales teams understand who attended, which companies they represent, and what type of follow-up makes sense.

CRM data can become incomplete or stale over time.

Contacts change jobs. Companies grow. Titles change. Firmographic fields go missing. Records become inconsistent.

For one-time cleanup or analysis projects, you can export a CSV, enrich the file, and use the results to identify missing data, improve segmentation, or prepare for a larger operational update.

For recurring CRM enrichment, an API workflow may be a better long-term fit. But for a one-time project or quick analysis, CSV enrichment can be a faster starting point.

Some teams work with IP address exports from website analytics, logs, reverse IP workflows, or other systems.

On their own, IP addresses may not be very useful for sales or marketing. But when enriched with company-level intelligence, they can help teams better understand account activity, identify website visitors, or support account-based marketing analysis.

For example, you might enrich an IP list to see which companies are visiting high-intent pages or engaging with important parts of your website.

CSV enrichment is especially useful when your need is immediate, file-based, and self-contained.

It is usually a good fit when:

For many self-serve users, the first step is not an API integration or a full data delivery conversation. The first step is enriching a single file so they can evaluate the data, complete a project, or move a campaign forward.

Batch Enrich is built for that moment.

We support multiple ways to access B2B data because different teams need data in different ways.

For many of our enterprise customers, APIs and flat files are the primary delivery methods. They are a better fit for recurring workflows, production systems, warehouse ingestion, large-scale data delivery, and broader data infrastructure.

CSV enrichment serves a different purpose.

It gives self-serve users a simple way to enrich a file directly, especially when the job is one-time, exploratory, or outside an existing technical workflow.

CSV enrichment is not meant to replace APIs or flat files.

It is a simpler entry point for users who already have a file and need enriched results. As a use case becomes more recurring, automated, or strategic, an API or flat file delivery model is often the better (and more cost-effective) long-term path.

But for a one-off list enrichment job, Batch Enrich helps you get value without starting with a technical build.

Out Batch Enrich tool lets you upload a CSV and enrich it with B2B Person, Company, or IP data.

The workflow is straightforward:

Behind the scenes, Batch Enrich uses our Enrichment APIs to find the best match for each record in your uploaded list. You get access to the same underlying enrichment capabilities without needing to call the API directly or build an integration first.

That makes Batch Enrich useful for non-technical users, one-off projects, and teams that want to quickly test whether enriched B2B data can help with a specific workflow.

One of the most important parts of any enrichment project is understanding coverage.

Two concepts are especially useful:

Match rate tells you the percentage of records that were successfully enriched.

Field fill rate tells you how often a specific field is populated among the matched records.

For example, if you upload 1,000 records and 950 are matched, your match rate is 95%. If 750 of those matched records include a job title, the field fill rate for job title is 75%.

That distinction matters because not every enriched record will have every possible field.

A good enrichment workflow should help you understand both whether records were matched and how complete the selected fields are. Batch Enrich lets you review match rate and field fill rate before purchasing a completed list, and you only pay for matched records.

For self-serve users, that visibility is especially helpful. You can evaluate coverage before deciding whether to purchase and download the enriched output.

The Batch Enrich tool gives self-serve users a simple way to enrich CSV files with B2B Person, Company, and IP data.

It is best used when you have a one-time list enrichment project or a simple spreadsheet-based process.

For ongoing data delivery, we also support APIs and flat files. Those are often better for recurring workflows, production systems, data infrastructure, and enterprise-scale use cases.

But when you just need to enrich a file, the Batch Enrich tool gives you a straightforward way to upload your CSV, review coverage, purchase matched records, and download enriched results.

B2B CSV enrichment is the process of uploading a spreadsheet of business records and appending additional person, company, or IP data. For example, you can enrich leads with job titles and LinkedIn profiles, companies with firmographics, or IP addresses with company-level intelligence.

Batch Enrich supports Person, Company, and IP enrichment jobs. Depending on the job type, you can enrich CSV lists with data such as professional attributes, company details, social profiles, contact data, revenue, funding data, firmographics, and other B2B data points.

Yes. Lead list enrichment is one of the most common CSV enrichment use cases. You can upload a CSV of prospects or contacts and enrich it with additional person and company data to support prioritization, segmentation, routing, and outreach.

Yes. Company enrichment can add firmographic and business data to company records, such as industry, employee count, revenue, location, company profiles, and other company-level attributes.

Yes. IP enrichment can help add company-level intelligence to IP addresses, which can be useful for website visitor identification, account intelligence, segmentation, and account-based marketing analysis.

No. CSV enrichment is file-based: you upload a CSV and download enriched results. APIs are better for real-time, recurring, or integrated workflows. Flat files are often better for large-scale enterprise delivery.

CSV enrichment is a good fit when you have a one-time or occasional enrichment job and already have records in a spreadsheet. APIs and flat files are better for ongoing enrichment, automated workflows, production systems, data infrastructure, and large-scale delivery.

No. Batch Enrich purchases are one-time purchases and do not require an existing subscription to our Enrichment APIs. All you need is a free PDL self-serve account to access the dashboard.

Batch Enrich uses our Enrichment APIs behind the scenes to find the best match for each record in a list. The difference is that Batch Enrich lets you run file-based enrichment jobs without calling the API directly.

Match rate is the percentage of records in an uploaded list that we are able to enrich.

Field fill rate shows how often a specific field is populated among matched records. For example, if 1000 records are matched and 750 include a job title, the field fill rate for job title is 75%.

CSV enrichment is best for self-serve users and teams with one-off or occasional enrichment jobs, especially when they already have a lead list, account list, customer list, candidate list, company list, or IP list in spreadsheet form.
