Your files stay on your device Config file tools Edit and inspect .env, INI, YAML, and .properties files with every change listed, plus chmod, CSV-to-SQL, and docker run conversion. 14 tools - .env editor Inspect and format .env files: duplicates, exports, quoting rules named. (/config/env) - INI editor Parse INI: sections, dotted paths, boolean coercions, last-wins duplicates. (/config/ini) - .properties editor Java properties: dotted keys, escapes decoded, comments counted. (/config/properties) - chmod calculator Octal ⇄ symbolic permission modes, special bits named for what they do. (/config/chmod) - CSV → SQL Paste CSV, get INSERT statements, quoted per standard SQL with NULLs by your choice. (/config/csv-to-sql) - docker run → compose Turn a docker run command into a compose service. Unmapped flags are listed, never dropped. (/config/docker) - nginx.conf explainer Paste an nginx.conf snippet: every directive explained in its block context, unknowns counted, nothing loaded or tested. (/config/nginx) - SSH config explainer Paste sshconfig or sshdconfig: Host blocks and every keyword explained, weakening settings called out, nothing connects. (/config/ssh) - YAML Format, validate, and convert YAML to and from JSON with a loss ledger. (/config/yaml) - TOML Format, validate, and convert TOML to and from JSON, with dates and big ints exact. (/config/toml) - XML Format, validate, extract, view the tree, and convert XML. Mapping stated, transform set declared, subset documented. (/config/xml) - CSV studio Sniff, profile, and convert CSV: column stats, type preview, formula guard. (/config/csv) - SQL to CSV Read INSERT statements back as CSV, TSV, JSON, JSONL, or Markdown. (/config/sql-to-csv) - umask What a umask clears, and the file (0666) and directory (0777) modes it leaves. (/config/umask) Your files are processed on your device. The few tools that talk to the internet say so before they do.
