About This Tool

The tool takes structured tabular data and applies deterministic formatting rules to produce clean, consistent tables for downstream consumption. Conceptually, it parses inputs into a canonical matrix, analyzes each column to determine appropriate alignment and width, and then renders a formatted string or exportable representation. This approach enables automation-friendly outputs that can be embedded in reports, documents, or code before distribution. The system is designed for engineers, data scientists, and writers who require reproducible results without manual adjustments. By supporting multiple input formats and export options, it reduces data-prep friction and ensures uniform presentation across platforms. The tool excels in pipelines where tables are generated programmatically and must align with strict column counts and precision rules. Unique value lies in its explicit handling of numeric vs text data, locale-aware formatting options, and a compact, well-defined output that can be consumed by other tools. Core features include CSV/TSV/JSON input parsing, column-width optimization, per-column alignment (numeric right, text left), numeric precision control, and export formats such as Markdown, CSV, or fixed-width text. Use cases include preparing tables for automated reports, software documentation, data dashboards, or test fixtures. The tool emphasizes deterministic behavior, predictable spacing, and easy integration with automation scripts, reducing manual edits and improving reproducibility.

How to Use

  1. Provide inputs: supply tabular data (CSV/TSV or JSON array) and optional formatting directives.
  2. Choose output format: select Markdown, CSV, or fixed-width text for downstream systems.
  3. Run formatting: tool parses data, computes column widths, applies alignment and precision rules.
  4. Retrieve outputs: obtain the formatted table string and accompanying metadata for validation.
  5. Validate results: review padding, alignment, and truncation; adjust inputs if necessary.

Frequently Asked Questions

Find Quick Answers

What input formats are supported?
The tool accepts CSV, TSV, and JSON arrays as data_matrix inputs. It can also interpret plain delimited strings if a delimiter is provided. For JSON, the data should represent an array of arrays or objects that map to a tabular shape.
What outputs are produced?
The primary output is a formatted_table string. Additionally, metadata includes the number of rows, columns, and max column width. Outputs can be exported as Markdown, CSV, or fixed-width text depending on the chosen format.
How does it handle inconsistent rows?
If rows have different lengths, the tool pads missing cells with empty strings to preserve column alignment. It also records a note in metadata about any padding or truncation performed during formatting.
Can I enforce numeric alignment or precision?
Yes. You can designate which columns are numeric and set numeric_precision. Numeric columns are right-aligned and rounded to the specified precision; non-numeric columns remain left-aligned.
