Features & use cases
Features
- Plain text rows are normalised by tabular-ir before Apache Parquet is written, preserving row order and typed values for txt-to-parquet.
- Flat TXT columns stay flat in PARQUET; presentation-only details are not carried forward.
- The converter treats the file as one logical table, so comments, prose around tables, and source metadata are skipped.
- Parquet schemas keep column names and inferred scalar types, but nested/repeated columns are flattened for table outputs.
Use cases
- Translate TXT integration payloads into PARQUET for another system.
- Inspect nested fields, arrays, and missing values before handing data to automation.
- Create clean fixtures for tests, demos, or support investigations.
- Share structured exports with teams that need a different file format.

Can I convert TXT to PARQUET in the browser?
Yes. Enabled tabular-ir conversions run in a browser worker, so regular web conversions do not upload your file.
Will spreadsheet formulas and styling survive?
No. The tabular engine preserves the visible table values and inferred types, not formulas, charts, merged cells, comments, or styling.
How are nested records handled?
Nested JSON, YAML, and XML objects become flattened columns. Arrays can remain JSON strings or expand into indexed columns.
Can I choose a workbook sheet?
This pair does not read a workbook, so there is no sheet option.
Is the PARQUET schema guaranteed?
Column names and scalar types are inferred from the input. Review warnings for ragged rows, nested fields, and unsupported destination features.
Everything you need
Browser-first privacy
CSV, JSON, XML, YAML, XLSX, and table conversions run locally when the source and target formats support it.
Warnings, not surprises
Formula drops, flattened arrays, sheet selection, and layout changes are surfaced as conversion warnings.
Batch and zip
Queue multiple files, download individual results, or package them into a zip for handoff.
API, CLI, MCP
Convert from browsers, scripts, automations, and AI assistants with the same warnings and outputs.
Team workspaces
Shared history, API keys, limits, and retention settings keep production conversions controlled.
Retention you control
Browser files never upload; server inputs auto-delete within 24 hours and outputs follow workspace retention.
