Core tools
From Messy Input to Reusable Output
A controlled desktop workflow for importing, transforming, validating, and exporting tabular data.
Transformations
- Text cleanup and normalization
- Find, replace, regex, and value mapping
- Split, merge, rename, and reorder columns
- Filter, deduplicate, and remove empty rows
Data quality
- Missing and duplicate values
- Email and phone checks
- Category variant analysis
- Per-column quality profiles
Reusable output
- Schema-aware saved workflows
- Reviewed column mappings
- Batch processing with per-file status
- CSV and Excel workbook output
Import with control
Review the Data Before Cleaning Starts.
Open CSV, TSV, TXT/delimited text, or Excel workbooks with controls for encoding, delimiter, headers, and worksheet selection. Preview the result before committing to an import.
- Detect or configure encoding and delimiters
- Choose header rows and Excel worksheets
- Detect and remove trailing blank columns
- Review wrapped records, malformed rows, repeated headers, and control characters
Ordered transformations
Build Repeatable Cleaning Workflows.
Arrange the operations a file needs, review the order, and reuse the workflow later. Each workflow can be as short or detailed as the data requires.

Illustrative sequence only. Workflows run the steps the user selects, in the order they configure.
Data Quality Center
Understand What Needs Attention.
Profile columns and surface common quality issues before deciding how to handle them. Email checks cover format and quality signals without connecting to inboxes.
- Missing values and duplicate rows
- Invalid emails, likely domain typos, disposable providers, and role/shared addresses
- Invalid phone numbers and inconsistent category variants
- Optional mail-domain checking when internet access is available
Schema-aware templates
Reuse the Workflow, Not Just the Steps.
Saved templates remember both the cleaning workflow and the source schema it was built for, helping later files map into the same process without guessing.
- Exact and normalized column matching
- Saved aliases and conservative fuzzy suggestions
- Review ambiguous mappings before running
- Keep one-to-one mappings and optionally remember successful aliases
Batch processing
Process a Queue Without Losing Control.
Choose a saved schema-aware template, add files or folders, optionally discover subfolders, and review compatibility before sequential processing begins.
- Per-file success and failure status
- Continue after an individual file fails
- Configurable output folder and collision-safe names
- Trailing blank-column cleanup for supported imports
Supported operations
Choose the Transformations the Data Needs.
Combine text, row, column, and value-normalization steps into an ordered workflow rather than relying on a one-click cleanup.
Text cleanup
- Trim whitespace
- Collapse whitespace
- Uppercase, lowercase, and title case
- Unicode normalization
- Remove special characters
- Find/replace and regex replacement
- Map values
- Fill empty cells
Rows
- Filter rows
- Remove empty rows
- Deduplicate rows
Columns
- Split and merge columns
- Rename, delete, and duplicate columns
- Reorder columns
Structured values
- Normalize email values
- Normalize phone numbers
- Normalize dates
- Normalize numbers
Local-first processing
Core Cleaning Stays on the Desktop.
Imports, transformations, profiles, templates, and exports run as local Windows workflows. Most email-quality checks also run locally.
Optional network check: mail-domain checking requires internet access and queries only the email domain. It does not connect to mailboxes or send verification messages.
