Built for agencies, RevOps consultants, and regulated teams that need to preflight HubSpot Contacts CSVs in the browser before import. Your file never uploads, nothing is stored, and the original CSV stays untouched.

Why this stays local
ReadyCSV is a browser tool, not a service. We hand you a workspace - your file never leaves it.
CSV parsing, edits and exports run in browser memory. No account, no upload, no AI calls, no data custody - useful when client or regulated data cannot leave your environment.
Each issue is tagged with what flagged it - a built-in HubSpot Contacts check or a local rule pack you chose. No live review or manual cleanup is provided.
With the Free Local plan, you can download the cleaned working copy and a plain-text Issue Report. You stay in control and review the file before importing.
What ReadyCSV doesn't do
How it works
Local parsing, local repair, local export. No uploads, no remote AI, no import guarantees. Just clear evidence before you decide.
Pick a file from disk or try the synthetic HubSpot sample. The file never leaves your browser.
In-browser workspace
See blockers, warnings and safe fixes. Apply suggestions locally or edit cells in the workspace.
Cleaned working copy
Download the cleaned CSV and an Issue Report. Your original file is preserved.
Cleaned CSV + Issue Report
Pick a CSV from your device. Load a CSV to see detected headers and a 10-row preview before destination checks start.
Your file never leaves your browser. CSV parsing, preview, edits and exports stay local.
Local project file
Save or restore this workspace with a local .readycsv file. It stays under your control, with no cloud sync or autosave.
A .readycsv project file may contain CSV data and local rule-pack settings. Store it securely and do not share it.
Optional local rule-pack checks
Built-in HubSpot Contacts checks run without a pack. If you want extra local checks, load a CSV and choose HubSpot Contacts first. The rule-pack loader will appear in the analysis view.
Rule packs run locally. Nothing is fetched or uploaded.

Join the launch listFor agencies and regulated teams
Use ReadyCSV internally to prepare client HubSpot Contacts CSVs before import when NDAs, GDPR, or regulated workflows make cloud uploads and AI tools a non-starter. ReadyCSV does not receive, access, review, process, or store client files, and does not provide any live review or manual cleanup service.

Frequently asked
No. CSV files are read from local disk and processed in browser React state. ReadyCSV does not send your CSV to a server.
No. ReadyCSV uses local parsing, validation, cleanup suggestions, and rule-pack checks. It does not call AI APIs.
For many agency, legal, healthcare, finance, and GDPR-sensitive workflows, client CSVs cannot be pasted into external AI tools. ReadyCSV keeps the preflight step in your browser tab: no upload, no AI call, no data custody.
ReadyCSV is designed for internal browser-only preflight work: you choose the file locally, review the findings locally, and export locally. It does not receive, store, review, or process client files. You still remain responsible for your NDA, client permissions, and import decisions.
CSV is supported in the browser workspace, including comma, semicolon, and tab-delimited imports. XLSX files are not imported in this version.
No. ReadyCSV checks email format, missing values, and duplicates locally, but it does not verify inbox deliverability or contact real people.
A local rule pack is an optional JSON file you choose from disk. It adds extra destination-specific checks, such as HubSpot Contacts checks, and runs in your browser without remote fetching or CSV upload.
Free Local includes Cleaned CSV for Import, Spreadsheet-safe CSV, and a source-labeled Issue Report from the current cleaned working copy. Excel-friendly CSV export will unlock with Pro Founder once paid tiers go live. The original file is preserved in memory and is not overwritten. ReadyCSV does not receive or store your file.
