The Privacy-First Developer & Data Import Utility Suite

FixMyImport provides fast, browser-native tools designed to clean messy spreadsheets, reformat datasets, and solve everyday developer tasks — with zero server uploads and guaranteed data confidentiality.

Why Choose FixMyImport Over Traditional Cloud Converters?

Most web-based CSV formatters, file splitters, and developer converters require uploading your proprietary files to remote cloud servers. Once uploaded, confidential customer lists, email databases, and private records are subject to server-side retention, accidental logging, and third-party exposure.

FixMyImport is engineered with a strict browser-first architecture. All parsing, conversion, and exporting tasks execute directly in your local browser runtime using HTML5 Web Workers and native Web APIs. Your spreadsheets and code snippets never leave your device.

Common Data Import Disasters and How We Solve Them

Spreadsheet exports rarely work on the first try. Here is how our suite prevents common import failures:

Delimiter Inconsistencies (Commas vs. Semicolons) — European and international versions of Excel commonly export spreadsheets using semicolons (;) or tabs rather than commas, causing platforms like Shopify to reject them. (FixMyImport auto-detects the source delimiter and automatically standardizes the file into RFC 4180 comma-separated formatting.)

Oversized File Rejections & Quota Errors — Platforms like Mailchimp (10 MB cap) and Shopify (50,000 product rows) immediately reject bulk imports that exceed their size thresholds. (Our in-browser batch splitter divides large files into targeted row counts or size chunks, packaged neatly into an instant ZIP download.)

Corrupted UTF-8 Byte Order Marks (BOM) — Invisible BOM characters () inserted by Windows programs cause import parsers to misread primary header names (e.g. 'Email' instead of 'Email'). (FixMyImport automatically detects, cleans, and strips Byte Order Marks, ensuring universal compatibility with database engines.)

Duplicate Customer Records & Whitespace — Accidental duplicate contacts inflate marketing bills and generate import collision errors in CRMs like HubSpot and Klaviyo. (Deduplicate thousands of rows in seconds based on email, customer ID, or all columns with clean whitespace trimming.)

Frequently Asked Questions About FixMyImport

Are any of my files or text uploaded to FixMyImport servers?

No. FixMyImport operates strictly inside your web browser. All CSV cleaning, binary conversions, and file splitting happen locally on your computer's CPU. Your data is never transmitted to any external server or saved in any database.

Why should I use FixMyImport instead of Excel or Google Sheets?

Spreadsheet software like Excel often mangles data during export: converting large numbers to scientific notation (e.g. 1.23E+11), stripping leading zeros from zip codes, and introducing non-standard delimiters. FixMyImport preserves your raw data formatting and handles batch splitting that spreadsheet apps cannot easily do.

Is there a file size limit for CSV processing?

Because processing occurs directly in your browser's memory, file size limits depend on your computer's RAM. Most modern devices can effortlessly process CSV files containing 500,000+ rows and 50–100+ MB without performance degradation.

Is FixMyImport free to use for commercial projects?

Yes, FixMyImport is completely free for personal, commercial, and enterprise usage without any hidden limits, watermarks, or subscription fees.

Can I use FixMyImport without an internet connection?

Yes. Once you load FixMyImport in your browser, all necessary scripts are loaded into memory. You can disconnect from the internet or work in airplane mode with full functionality.

What platforms are supported for CSV imports?

Our tools output standardized RFC 4180 CSV files fully compatible with Shopify, WooCommerce, Mailchimp, Klaviyo, HubSpot, Salesforce, ActiveCampaign, Google Contacts, and SQL database importers.
