Tool chooser

Which data tool should I use?

Use the smallest tool that matches the data shape. Validate before converting, infer schema before handing data off, and export to XLSX only after the table shape is clean.

Decision map

Start with the closest job

Make raw JSON readable, valid, smaller, or schema-checked.

Validate and format JSON

Use when: Use this path when pasted API output, config, logs, or webhook payloads need a safe browser-local cleanup pass.
Avoid when: Do not paste secrets, private tokens, or production credentials into tools unless you are comfortable handling them in your browser session.

Convert JSON to CSV for spreadsheets Clean CSV data and export XLSX

Validate, infer columns, dedupe rows, sort rows, and move between CSV/TSV/JSON.

Clean CSV before importing

Use when: Use this path before spreadsheet import, CRM upload, BI cleanup, or a client handoff.
Avoid when: Do not rely on CSV cleanup to fix unknown business logic. Confirm required columns and source-system rules first.

Clean CSV data and export XLSX Convert JSON to CSV for spreadsheets

Create spreadsheet files after validating and shaping data.

Export JSON or CSV to XLSX

Use when: Use this path when a recipient needs an Excel-compatible file but the source data is JSON or CSV.
Avoid when: Do not use XLSX export as the first cleanup step. Validate and flatten table shape before exporting.

Clean CSV data and export XLSX Convert JSON to CSV for spreadsheets

Move data between JSON, XML, YAML, TOML, ENV, INI, NDJSON, and JSON Lines.

Convert between structured formats

Use when: Use this path for config migration, API payload review, quick ETL prep, or table extraction from nested formats.
Avoid when: Format conversion can lose comments, ordering expectations, or type nuance. Keep the original source file when fidelity matters.

Convert JSON to CSV for spreadsheets Clean CSV data and export XLSX

Convert Markdown, HTML, plain text, URLs, Base64, timestamps, robots.txt, and sitemaps.

Work with text-like web data

Use when: Use this path for publishing, SEO QA, docs cleanup, scraping-adjacent cleanup, and developer handoffs.
Avoid when: These tools transform syntax. They do not crawl the web or verify live external URLs unless the specific lookup tool says so.

Decode or calculate technical references without starting a network workflow.

Inspect hashes, tokens, and certificates

Use when: Use this path for local verification, support tickets, configuration review, and implementation debugging.
Avoid when: Decoders are not security guarantees. Do not treat decoded JWTs or certificate text as proof that a system is safe.
