Bulk Phone Normalizer is a browser-based CSV phone number cleanup tool for teams that need cleaner phone data before CRM, dialer, spreadsheet, or API import.
Upload a CSV, choose the phone column, optionally select a country column, and the tool separates safer rows from risky rows. Safe phone numbers are converted into E.164 format, while unclear rows are placed into a separate needs-review file so they can be checked before import.
It is useful for cleaning messy CSV exports that contain inconsistent phone formats, local numbers, international numbers, extensions, notes, or rows that may cause failed imports.
Key benefits:
Bulk Phone Normalizer is designed for marketers, operators, sales teams, data cleaners, virtual assistants, and anyone who needs a simple CSV phone cleaner before uploading contacts into another system.

Bulk Phone Normalizer's answer
Bulk Phone Normalizer focuses specifically on cleaning messy phone number columns inside CSV files before import.
Instead of only validating one number at a time, it helps users process bulk CSV data, convert safer phone numbers into E.164 format, preserve the rest of each row, and separate risky or unclear rows into a needs-review file.
It is also browser-based, so users can clean CSV phone data without creating an account or uploading sensitive contact files to a server.
Bulk Phone Normalizer's answer
Bulk Phone Normalizer is built for a practical workflow: cleaning CSV phone columns before CRM, dialer, spreadsheet, or API import.
Many phone validation tools focus on lookup APIs or enrichment. Bulk Phone Normalizer is simpler and more focused. It helps users prepare messy CSV files, normalize safer numbers to E.164 format, and separate uncertain rows for manual review.
It is a good choice for users who want a fast, lightweight CSV phone cleaner without setting up an API, creating an account, or manually fixing every row in a spreadsheet.
Bulk Phone Normalizer's answer
The primary audience is anyone who works with contact lists, CRM exports, lead lists, spreadsheet data, or phone number columns in CSV files.
This includes marketers, sales teams, operations teams, virtual assistants, data cleaners, agencies, CRM users, and developers preparing phone data for import into another system.
Bulk Phone Normalizer is especially useful for people who need cleaner phone numbers before uploading data into a CRM, dialer, messaging tool, database, or API workflow.
Bulk Phone Normalizer's answer
Bulk Phone Normalizer was created to solve a common data-cleaning problem: messy phone number columns inside CSV files.
Phone numbers often arrive in different formats, with missing country codes, local formats, spaces, symbols, extensions, notes, or inconsistent formatting. These issues can cause failed imports, broken CRM records, and extra manual cleanup work.
The goal of Bulk Phone Normalizer is to make this process faster by giving users a simple browser-based tool to clean phone columns, convert safe rows to E.164 format, and separate risky rows for review.
Bulk Phone Normalizer's answer
Bulk Phone Normalizer is built as a browser-based web tool using modern front-end web technologies.
Its core workflow uses client-side CSV processing, phone number parsing and normalization, E.164 formatting logic, and browser-based file handling so users can clean CSV data directly in their browser.
I've started using this as my main IDE for new projects when I'm trying things out. If it keeps getting better at the rate it has been, it'll be even better than coding locally.

Managing reactive state and dependent computations in JavaScript can get complex, especially when combining asynchronous and synchronous data. RS-X is a library that allows you to bind expressions to plain objects and makes the parts of the model used by those expressions fully reactive. Dependent computations automatically update when the underlying data changes. RS-X is framework-agnostic. While it can drive UI... - Source: Hacker News / 5 months ago
I like htmx, LiveView, React and Solid. They are great at different points, so I try to combine them in Solv (Stateless Offline-capable LiveView) and write a prototype to show the benefits. Solv's main idea is that stateless servers keep client's state in a volatile cache. It enables server components that are also interactive, which is best of both worlds between LiveView and htmx. Then fine-grained reactivity is... - Source: Hacker News / 8 months ago
