If this sounds like your week

Every Shopify download needs the same scrub before it’s usable.

Product, customer, and order files come out of the storefront with tag columns in mixed casing, the same shopper repeated across several orders, blank Handle values, and addresses typed in every variation of upper and lower case. Before that data is fit for a mail-merge, a report, or a re-import, somebody has to standardize all of it by hand.

Where tooling usually breaks

Hand-editing a storefront file is nerve-wracking.

Touch the wrong header or drop a required column and the re-import fails outright — or worse, silently overwrites live catalog and variant data. Doing that delicate surgery fresh on every download is slow, and one slip can ripple straight into the live store your revenue depends on.

Where CSVPrune lands

A trusted, reusable scrub built for storefront data.

CSVPrune ships a Shopify pack you can inspect, rename to your conventions, and adapt: canonicalize Handle and header names, fold addresses to lowercase, standardize tag formatting, and collapse repeat shoppers by email down to a single most-recent row. Tailor it to your storefront once and every later download is standardized identically in seconds — all on your device, so buyer and fulfillment details never travel off the machine.

What you get

Feature highlights

Opens what Excel chokes on

scroll, search, filter, and type-aware sort 100k+ row files instantly in a virtualized grid—no 1,048,576-row wall and no freezing.

Fixes broken exports

auto-detects and overrides delimiters (comma, semicolon, tab) and encodings (UTF-8/16, Latin-1) so CRM, Shopify, and Google Forms files stop arriving garbled—and leading zeros and long IDs are never silently mangled.

Deterministic cleaning pipeline

trim, normalize emails, find/replace (literal or regex), coerce numbers, currency, dates, and booleans, dedupe by any key column, and point-and-click prune rows—composed in the order you choose.

Live formula engine

create calculated columns with real-time preview and a ghost column in the grid, using column references, arithmetic, string functions, and helpers like coalesce()—saved as replayable steps.

Clean once, replay forever

save any sequence as a named recipe, apply it in one click, batch-run it across a folder, or point a watch folder at it so every new CSV is cleaned automatically.

Private by design

every row stays in local memory, with no cloud, no telemetry, and no network calls—auditable with Wireshark. Export to CSV, JSON, or XLSX, or run an audited export with a full before/after sidecar.

Especially when

  • Clean and dedupe messy CSV exports on Windows without uploading sensitive data to a web-based CSV cleaner
  • Open, search, and sort CSV files that are too large or too slow to handle in Excel
  • Fix CSV encoding and delimiter problems (UTF-16, Latin-1, semicolon, tab) that corrupt CRM, Shopify, and Google Forms exports
  • Replay the same cleaning steps on recurring files automatically instead of repeating them by hand every week

Who benefits

Real-world scenarios

The store operator

Your Shopify customer export has duplicate rows across orders, mixed-case emails, and inconsistent tags, and you need it clean before a mail-merge without risking the live catalog.

You install and tweak the Shopify Recipe Pack in CSVPrune, dedupe customers by email keeping the latest, standardize the tags, and reuse the saved recipe on every future export.

The merged mailing list

You combined three sign-up exports and the same subscriber now appears multiple times with slightly different capitalization, so your count is inflated and people would get duplicate emails.

CSVPrune collapses the list by lowercased email, keeps the most recent row for each person, and flags the fuzzy near-matches for a quick review — leaving one clean record per subscriber.

The Monday morning ritual

Every Monday you download the same report and run the identical cleanup — headers, test rows, dedupe, dates — entirely by hand, and it eats the first part of your week.

You save the sequence as a recipe and point a watch folder at your downloads, so each new export is cleaned and written out automatically the moment it lands.

Deep dive

A repeatable, low-risk cleanup for Shopify product, customer, and order CSVs

Shopify exports are consistent in their inconsistency: customer files repeat the same person across orders, tag columns mix casing and spacing, handles and emails arrive in whatever case the data was entered, and a re-import is unforgiving about headers and required columns. Cleaning each export by hand is both slow and risky, because a wrong edit can fail the import or overwrite live catalog data. CSVPrune turns that into a saved, trustworthy routine. It ships a Shopify Recipe Pack that you can preview before installing, rename to match your conventions with live conflict warnings, and then customize: normalize the header row so column names are canonical, lowercase and trim email addresses, standardize tag formatting, and dedupe customers by email while keeping the most recent record. Saved as your store's recipe, that exact sequence reapplies to the next export in one click, and a watch folder can run it automatically on every download. Because everything happens locally, sensitive customer and order data never leaves your machine, and an audited export gives you a before/after record of precisely what changed — useful when the cleaned file is going back into a live store. The result is a Shopify workflow that is fast, repeatable, and far less nerve-wracking than editing the raw export by hand.

FAQ

Straight answers—no glossary dump

How do I clean a Shopify CSV export before re-importing it?

CSVPrune includes a Shopify Recipe Pack you can preview, rename, and install, then customize for your store: normalize headers, lowercase and trim emails, standardize tags, and dedupe customers by email while keeping the most recent record. Save it as your recipe and the next export is cleaned the same way in one click, or via a watch folder automatically. Everything runs locally, so customer and order data never leaves your machine, and an audited export records exactly what changed.

Is CSVPrune private, and does it work offline?

Yes on both counts. CSVPrune runs entirely on your machine with no cloud, no telemetry, and no network access of any kind — there is no networking code in the app, so it works fully offline and nothing you load is ever uploaded. Your data stays in local memory for the session, and only minimal settings such as window state and recent paths (which you can turn off) are saved to disk. You can verify the zero-network behaviour with a connection monitor.

What file types and sizes does CSVPrune handle?

CSVPrune loads CSV files with comma, semicolon, or tab delimiters (auto-detected, with a manual delimiter and encoding override for UTF-8, UTF-16, and Latin-1) and is designed for large files, with smooth performance on hundred-thousand-row datasets and guidance up to around 500 MB. You can export your cleaned data to CSV, JSON, or XLSX, copy it to the clipboard, or use an audited export that adds a full before/after sidecar for compliance.

How much is CSVPrune, and is it a subscription?

CSVPrune is a one-time purchase on the Microsoft Store — no subscription and no account required to use it. You own the version you buy and it keeps working offline. Use the Microsoft Store button on this page for the current listing and price, and because the privacy posture is structural rather than a setting, you can verify the local-only behaviour yourself at any time with a network monitor.
