- [OpenAPI to Postman Collection](https://elysiatools.com/en/tools/openapi-to-postman-collection): Turn an OpenAPI 3.x or Swagger 2.0 spec (JSON/YAML) into an importable Postman Collection v2.1.0 with folders, variables, auth and example responses.
- [YAML-JSON Converter](https://elysiatools.com/en/tools/yaml-json-converter): Convert between YAML and JSON formats
- [Config File Semantic Diff](https://elysiatools.com/en/tools/config-file-semantic-diff): Compare JSON, YAML, TOML, and dotenv configurations by key path while ignoring ordering and formatting noise.
- [JSONata Query & Transform Studio](https://elysiatools.com/en/tools/jsonata-query-transform-studio): Preview JSONata-style queries and transformations, compare results across sample payloads, and export the transformed output as JSON, CSV, YAML, or Markdown
- [JSON Schema to Zod Schema Converter](https://elysiatools.com/en/tools/json-schema-to-zod-schema-converter): Convert JSON Schema JSON/YAML definitions into ready-to-use Zod schemas with nested objects, arrays, enums, and common validation rules
- [WireGuard/OpenVPN to Clash and sing-box Config Bridge](https://elysiatools.com/en/tools/wireguard-openvpn-to-clash-singbox-bridge): Convert pasted WireGuard or OpenVPN client text into Mihomo/Clash YAML or sing-box JSON with secret-field diagnostics; do not share private keys
- [TOML / INI / HCL / .env / Nix / dotenv ⇄ Kubernetes ConfigMap & Secret Config Format Bridge](https://elysiatools.com/en/tools/toml-ini-hcl-envfile-nix-dotenv-kubernetes-configmap-secret-config-format-bridge): Convert configuration files between dotenv .env, TOML, INI, Java .properties, YAML, JSON, HCL (Terraform/Vagrant native syntax) and Nix attribute sets, and emit Kubernetes ConfigMap or Secret manifests. Template placeholders (${VAR}, {{var}}, envsubst) are preserved verbatim, type inference provenance (string/int/float/bool/list) is tracked, HCL block labels fold into nested keys, and a round-trip diff calls out non-equivalent settings — dropped keys, re-typed values and rewrites — instead of coercing them silently.
- [XLSX API To Sheet](https://elysiatools.com/en/tools/xlsx-api-to-sheet): Fetch JSON from REST or GraphQL API and write mapped records into an Excel sheet with automatic pagination
