What format does this expect each item to be in?

Each item should be one or more 8-character binary bytes (only "0"s and "1"s), separated by spaces, exactly what the Text List to Binary List Converter produces.

What happens if a byte isn't exactly 8 bits?

The tool reports an error naming the exact item and the offending token, since a byte that isn't exactly 8 characters of "0"/"1" can't be decoded unambiguously.

What if the bytes decode to something that isn't valid UTF-8?

You'll get a clear error naming that item rather than silently producing garbled or replacement characters.

Can I go the other direction?

Yes, use the companion Text List to Binary List Converter to turn plain text list items into their binary form.

Binary List to Text List Converter - Decode Binary Bytes per Item

Overview

Introduction

Once you have a list of binary-encoded values, from a homework assignment, a captured packet dump, or a puzzle, you need a reliable way to turn each one back into readable text without decoding bytes by hand.

This tool does exactly that: it walks each item's space-separated binary bytes and decodes them back to UTF-8 text, catching malformed input along the way.

What Is Binary List to Text List Converter?

The Binary List to Text List Converter is a per-item decoder: it splits each item on whitespace into binary byte tokens, validates each one is exactly 8 bits, and decodes the resulting bytes as UTF-8.

It's the exact inverse of the Text List to Binary List Converter, so text converted there and decoded here round-trips losslessly.

How Binary List to Text List Converter Works

The input is split into items on your chosen separator; each item is then split on whitespace into individual byte tokens.

Every token is checked against `^[01]{8}$` before being parsed with `parseInt(token, 2)`, and the resulting byte array is decoded with a UTF-8 `TextDecoder` in strict (fatal) mode so invalid byte sequences raise an error instead of silently producing replacement characters.

When To Use Binary List to Text List Converter

Use this whenever you have a list of binary-encoded strings, from an exercise, a generated fixture, or another tool, and need the plain text back.

It's also useful for validating that a hand-written or generated binary string is well-formed before feeding it to something else.

Often used alongside Text List to Binary List Converter, List Base64 Decoder and YAML to List Converter.

Features

Advantages

Validates every byte strictly, so malformed binary is caught immediately with a specific, item-level error.
Correctly reassembles multi-byte UTF-8 characters, not just single-byte ASCII.
Round-trips exactly with the companion Text List to Binary List Converter.

Limitations

Only decodes well-formed 8-bit binary bytes; it doesn't attempt to guess intent from malformed input.
Assumes UTF-8 encoding; binary produced with a different text encoding won't decode correctly.

Examples

A simple ASCII item

Input

01001000 01101001

Output

Hi

Two 8-bit bytes decode back to the two-character ASCII string "Hi".

A multi-item list

Input

01100001
01100010
01100011

Output

a
b
c

Each item's 8-bit bytes are decoded independently, so a three-item list produces three decoded characters, one per line.

Best Practices & Notes

Best Practices

Make sure bytes are separated by single spaces and items by your chosen list separator before pasting in a large batch.
If you generated the binary elsewhere, double-check it's UTF-8, not UTF-16 or another encoding, before decoding here.

Developer Notes

Byte tokens are validated with the regular expression `/^[01]{8}$/` before `parseInt(token, 2)`; the resulting `Uint8Array` is decoded with `new TextDecoder("utf-8", { fatal: true })` so any invalid UTF-8 byte sequence throws instead of silently substituting U+FFFD.

Binary List to Text List Converter Use Cases

Decoding a list of binary strings from a homework assignment or coding exercise
Validating that generated binary test fixtures decode back to the expected text
Reversing output from the Text List to Binary List Converter to confirm a lossless round trip

Common Mistakes

Leaving extra or missing spaces between bytes, each byte token must be exactly 8 characters of "0"/"1" with whitespace as the only separator.
Mixing up which separator splits items versus which character splits bytes within an item, spaces always separate bytes; your chosen separator splits items.

Tips

If decoding fails, check the reported item number first, the error always names which item and byte caused the problem.
Use this alongside the Text List to Binary List Converter to sanity-check any binary-format tooling you're building.
