This tag includes 17 Diff tools for working with diff files and data. ## Tools - [AGEX Bundle Diff](https://elysiatools.com/en/tools/agex-bundle-diff): Compare two AGEX bundles and highlight metadata or protection-setting differences - [AI Prompt A/B Variant Generator](https://elysiatools.com/en/tools/ai-prompt-ab-variant-generator): Generate controlled A/B variants of a prompt across the persona, tone/style, output format, and constraints dimensions, then compare them side by side with a heuristic rubric score and a word-level diff against the baseline. A reproducible way to test how a prompt behaves under different framings before picking one for production. - [API Breaking Changes Detector & Migration Planner](https://elysiatools.com/en/tools/api-breaking-changes-detector-migration-planner): Compare two OpenAPI 3.x schemas, identify breaking changes, grade client impact, and suggest migration or compatibility strategies - [API Response Diff & Semantic Analyzer](https://elysiatools.com/en/tools/api-response-diff-semantic-analyzer): Compare two API response payloads, highlight field-level diffs, and classify likely functional changes versus harmless runtime drift - [Audio Diff](https://elysiatools.com/en/tools/audio-diff): Compare two audio files and show their differences - [CSV / Excel Diff Tool](https://elysiatools.com/en/tools/csv-excel-diff-tool): Compare two CSV or XLSX datasets and export a PDF report with row, column, and cell-level differences - [CSV Malformed Row Surgeon](https://elysiatools.com/en/tools/csv-malformed-row-surgeon): Surgically repair malformed CSV rows one at a time: unescaped (stray) quotes, mixed delimiters (tab/semicolon/comma in the same file), BOM-prefixed headers, CRLF/CR line endings and trailing empty lines. The surgeon parses tolerantly, shows a row-level red/green diff of every change it made (before → after, with the repair reason tagged), lists the rows it accepted unchanged, and emits the cleaned CSV.
