What this tool does

CSV and TSV use quoted text fields and can enable spreadsheet-formula prefixing. JSON output is an array of objects whose values remain strings. Markdown output escapes pipe characters and displays cell line breaks as breaks.

How to use it

  1. Load a table with unique headers and consistent row widths.
  2. Choose an output format and review the formula-prefix setting for CSV or TSV.
  3. Convert, inspect the result preview, and download the new file.

2. Check the input

Confirm the header and a few records before applying a rule.

Questions

What to expect

Will JSON numbers be converted to numbers?

No. Every cell is exported as a JSON string so identifiers and leading zeroes stay visible.

Does Markdown preserve embedded newlines?

A cell line break is displayed as “<br>” to keep each record on one Markdown table row.

Review the destination rules. A valid CSV or a clean report does not guarantee that another system will accept the file. Keep your original and verify any export before importing it.
