Exporting match results

Exporting match results

RegexCraft can export Match results from the Test panel (Matches & Groups) as CSV or JSON. There are no license keys involved — export is available in the same free personal / paid business build.

When to use Export

  • Share match samples with a teammate
  • Feed results into a spreadsheet or script
  • Archive how a pattern behaved against a subject snapshot
  • Debug group captures offline

How to export

  1. Open Test mode (Ctrl+1).
  2. Enter a pattern and subject so matches appear under Matches & Groups.
  3. Use the export buttons next to Run:
    • CSV — save a spreadsheet-friendly file
    • JSON — save a structured file with metadata
    • Copy JSON — put the JSON document on the clipboard (no save dialog)

Suggested filenames look like regexcraft-matches-YYYYMMDD-HHMMSS.csv / .json.

CSV format

Columns:

Column Meaning
MatchIndex Zero-based match number
Value Full match text
Index Start offset in the subject
Length Match length
GroupN_Name Capture group name (or number)
GroupN_Success true / false
GroupN_Value Captured text
GroupN_Index Group start offset
GroupN_Length Group length

Group columns are expanded for every group number greater than 0 that appears in the result set. Group 0 (full match) is already represented by Value / Index / Length.

Values that contain commas, quotes, or newlines are CSV-escaped per usual rules.

JSON format

The JSON document includes:

  • exportedAt — UTC timestamp
  • pattern, subject
  • flavorId, flavorDisplayName
  • engineId, engineDisplayName
  • success, errorMessage, durationMs
  • options — ignoreCase, multiline, singleline, explicitCapture, ignorePatternWhitespace
  • matches[] — each with matchIndex, value, index, length, and groups[]

This is the preferred format for tools and scripts.

Notes

  • Export uses the last successful Test run. Fix pattern errors before exporting.
  • Empty match lists still export (header-only CSV / empty matches array) after a successful run.
  • GREP file hits and Library import/export are separate features and may arrive in a later release.
  • Compare mode has its own Copy summary for a text report across flavors — that is not the same as match CSV/JSON export.
