Batch Converter: Process Multiple Lines of Text Online
Batch Converter applies one operation to multiple lines of input at once. Enter one item per line, then choose Base64, URL, or hex encoding or decoding, a case operation, reverse, or trim. The tool returns a result for each line, and a line that fails conversion displays its error inline so the rest of the batch can still be processed.
Batch Converter is a browser-based tool for applying the same text operation to many inputs at once. To convert multiple lines of text, enter one item per line and select an operation. The tool processes each line separately, which makes batch conversion useful when repeating a transformation across a list of values.
Available operations include Base64, URL, and hex encoding and decoding, as well as case, reverse, and trim. The selected operation is applied to each input line, and a line that fails conversion reports its error inline instead of breaking the batch. This lets you identify which values need attention while keeping the other results available.
These operations handle different needs: Base64 and hex represent data in encoded forms, URL encoding prepares text for use in URLs, and decoding reverses the corresponding encoding. Case, reverse, and trim transform text rather than encoding it. Converting a list in one pass can save repetitive work when preparing values or checking the results of an operation.
Batch Converter is free and runs entirely in your browser. Your input is processed on your device; it is not uploaded, stored, or sent to a server. Once the page has loaded, the tool works offline. It can help developers and DevOps engineers who need to apply or verify the same text transformation across multiple values.
Step 1: Enter or paste your input, putting one item on each line. Each line is handled as a separate item in the batch.
Step 2: Choose the operation to apply, such as Base64, URL, or hex encoding or decoding, case, reverse, or trim.
Step 3: Review the results for each line. If a line fails conversion, its error appears inline rather than stopping the whole batch.
Step 4: Copy the representation or cleaned text you need from the results.
Use case: Encode several strings with the same Base64, URL, or hex operation instead of processing them one at a time.
Use case: Decode a list of Base64, URL-encoded, or hex values and review each result separately.
Use case: Apply a case operation to multiple lines when preparing text in a consistent form.
Use case: Trim whitespace from a batch of pasted values before using them elsewhere.
Use case: Reverse multiple input lines with one operation when you need to inspect or transform their text.
Use case: Check a batch containing invalid values: conversion errors appear beside the affected lines, while other lines can still be processed.
