Fix messy CSV data and avoid import errors
Stop fixing CSV imports by hand. Asphorem automatically maps columns, standardises picklist values, and normalises dates to your need — so your data imports cleanly into HubSpot, Salesforce, or any other tool. Free to start.
Your file rows never leave your browser — only unique column values are processed. Nothing is stored or shared.

You know this feeling.
You receive a CSV export. Before you can import it anywhere, you spend an hour renaming columns, fixing capitalisation, wrestling with three different date formats, and staring at Excel for no reason.
Then the same file arrives again next week.
Mixed languages, inconsistent headers, 3 date formats, case chaos.
Unified schema, canonical values, normalized dates. Ready to import.
Map once. Import forever.
The CSV Normalizer takes your messy export and turns it into clean, structured data — without touching the data manually.
Upload your CSV
Drag & drop or browse. Any export from HubSpot, Salesforce, Shopify, Pipedrive, or any tool that outputs a CSV file.
Map columns & match values
Assign each column to a canonical property from your library. AI automatically maps cell values to your allowed picklist values — across languages, typos, and formats.
Reuse mappings in one click
Download your file instantly. Every session is saved to your history. Next time you receive the same file format, hit "Reuse mapping" and skip straight to download — no re-mapping required.
The AI that actually understands your data.
Not just fuzzy search. Asphorem's AI matches picklist values semantically — across typos, abbreviations, different languages, and numeric range formats.
Built to get faster every time you use it.
Every file you process builds your reusable library of properties and mappings. The more you use Asphorem, the less work each task requires.
AI value matching
What used to mean hours of find & replace across every column is done in seconds. The AI resolves typos, language variants, and date formats in one pass — so you skip straight to download instead of cleaning row by row.
Properties library
Define reusable properties with types — Text, Number, Date, Picklist. Set allowed values once. Build your library over time, reuse it across every file.
Presets
Group properties into presets for each use case — "HubSpot Contact Import", "Shopify Product Export". Pre-fill column suggestions on every new file automatically.
One-click reprocessing
Save a column-to-property mapping as a named template. Next time you receive the same file format, select it and skip straight to download — no re-mapping required. The tool alerts you if the source structure has changed.
Session persistence
Mapping work is auto-saved in your browser as you go. Close the tab by accident — re-upload the same file and pick up exactly where you left off. Your file rows are never sent to a server.
Column filtering
Choose exactly which columns make it into the output file. Drop irrelevant fields and rename headers to match your target system — all without touching the source file.
