Browser-private free tools
Compare, missing-record, dedupe, merge/join, formula and converter tools use the File API and local exports. Public routes do not accept spreadsheet file POSTs.
Features
One product, two privacy boundaries
Free tools and the default Reconcile workspace process files on your device. Saving stores selected metadata. An optional server workspace supports hosted jobs, private exports and schedules.
CSV and lightweight XLSX support
CSV/TSV use a local quoted-field parser. XLSX reads Office Open XML ZIP/XML structures in the browser and focuses on tabular values.
Focused tool variants
Compare Excel, compare CSV, join-by-ID, inner/left/right/full joins and other variants share audited engines while addressing distinct user tasks.
Local converters
CSV↔Excel, CSV↔TSV, CSV↔JSON and split-file workflows create downloads locally without sending source data to ReconNimble.
Deterministic formula generator
VLOOKUP, HLOOKUP, XLOOKUP, INDEX/MATCH, FILTER, COUNTIF and COUNTIFS run locally. An optional AI mode may be added later.
Opt-in share links
Formula and result permalinks are created only after an explicit publish action. Duplicate signatures reuse canonical URLs and shared links remain noindex.
Two- to five-source Reconcile
Compare two to five sources locally within your plan limits, with exact keys, amount/date tolerances and fuzzy suggestions for human review. The optional server workspace also supports saved profiles and scheduled reports.
Audit and private exports
Reconcile records source hashes, mappings, rules and resolutions and provides CSV/XLSX/PDF/audit outputs through private routes.
Admin-panel controls
Manage tool caps, variants, plans, content, AdSense slots, optional AI settings, consent controls, contact messages, diagnostics and migrations.
Dormant by default
AdSense, affiliate placements, billing and AI are all OFF at fresh installation. Public tools and the rule-based formula generator continue to work without any of them.
