TidyRows — Local CSV cleanup

Preview CSV cleanup, undo changes, and reuse local recipes. Your CSV files stay on your device.

Clean CSV exports for analysis, research and everyday spreadsheet work without uploading your files. Free tools remain free Inspect blanks, distinct values, outer spaces, leading zeros and formula-like values. Search the whole file, jump between pages and columns, and inspect complete cell values. Trim selected columns, remove empty rows and exact duplicate rows, or review duplicates by selected columns and choose which records to keep. Preview every edit and removal, compare originals, download a complete proposed review, undo ten steps and export CSV/TSV. Save three local recipes. Optional TidyRows Pro • Batch cleanup: apply a saved recipe to up to 20 matching CSV/TSV files (25 MB total). Each file receives a separate review and export. Mismatched schemas are skipped; originals stay untouched. • Column standardization: build ordered rules for lowercase, uppercase, collapsing spaces/tabs and exact-value replacement. Scope every rule to a column, preview before applying, and save rules in recipes. • Portable recipe library: save up to 100 recipes, export a JSON backup and import recipes on another device. Existing recipes are preserved when Pro expires; premium rules require active Pro. Pricing and cancellation US$9/month or US$79/year, plus applicable tax. Both plans include a 14-day free trial and three device activations per license. Automatically renews after the trial and each billing period until cancelled. Cancel before the trial ends to avoid a charge. Manage cancellation and payment details through Lemon Squeezy My Orders or your receipt. Deactivating a device or uninstalling does not cancel billing. Local processing and privacy No CSV uploads, analytics, tracking, browsing-history access or remote code. CSV contents stay in tab memory until close/reload. Recipes store names, headers, cleanup choices and any exact replacement text locally. Reviews and recipe backups may contain sensitive values and are downloaded only when requested. Optional Pro checkout is hosted by Lemon Squeezy. License activation, verification and deactivation send only the license key, activation identifier and generic device label to its public license API. No CSV rows or recipes are sent. Pro actions require online validation. A temporary network failure pauses premium actions without deleting your work; free tools remain available. Preserve text values Identifiers with leading zeros, Unicode, quoted fields and multiline content stay text. No automatic number/date conversion. Single-file export offers UTF-8 BOM and apostrophe-based formula protection. Formula protection changes matching values; choose it for your destination application. Exports normalize quoting and line endings. Per-file limits: UTF-8 CSV/TSV, 5 MB, 50,000 data rows, 200 columns, one million cells. A header row is required. TidyRows does not certify compatibility with every spreadsheet or import platform. Screenshots use synthetic demo data; Pro demonstrations were captured with a test license.
